Hi all
I'm running the qmail package for some time now and I got now a special
error when sending a message to a user in my virtualdomains (vpopmail):
"
Hi. This is the qmail-send program at turkey.rogatec.ch.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<[EMAIL PROTECTED]>:
User is over quota email returned
"
I haven't installed a quota or something like that! The user uses now 52MB
Harddisk space with his mails (we use imap). How can I increase his quota,
so the error doesn't occurrs?
Thanks for your help

Hi all
I'm trying to use vpopmail to allow user that autenticate via pop3 the
user of smtpd.
I create a user with vadduser e vaddpasswd then i try to connect
to the qmail-pop3d telnet localhost pop-3 i insert:
user prova or user prova%virtualdomain
pass prova
-ERR this user has no $HOME/Maildir
I get this error if i try with a /etc/passwd users such as a virtual
user.
Here it's my inetd.conf startup line for pop3
...
/var/qmail/bin/qmail-popup rtsystem.com /home/vpopmail/bin/vchkpw

Actually, your e-mail client wrapped it. Mine doesn't wrap, and it
came in on two lines.

I recently started monitoring qmail-smtpd's activity via "tcpserver -v",
and at the moment it's burning through a steady 15-20 concurrencies,
scrolling by beyond readability.
Meanwhile, as I "tail -f maillog" for qmail-send's activity, it sits
predominantly idle, with an occasional message to process. Now,
regardless of whether it's local or remote, it should get picked up by
qmail-send, right?
So the question then is, if it's not receiving mail, what is qmail-smtpd
doing? Is it receiving connections from known spammers on my tcp.smtp
list, and dropping them? A quick scan of IP's doesn't jibe with that
theory; plus there's no "access denied" message shown. I'm suspicious of
all the:
2000-07-17 09:55:44.476546500 tcpserver: end 99787 status 256
Looking at tcpserver.c, I can't tell what this means. I looks like it
has something to do with the wait() function. Can one of you Unix/C
gurus lend a hand?
Thanks :)

The "status 256" is an abnormal exit code; qmail-smtpd has rejected the message
and the message isn't being queued.
My guess is that some dopey Windows mail server is sending you a message with
bare linefeeds. Your server rejects the message (with a 4xx code) which the
dopey Windows server sees as an invitation to try to deliver the message again
immediately. I've seen Windows hosts try to send the same message tens of
thousands of times in a day.
It could be something else altogether, but I've seen the above happen many
times.

This is in the documentation, FAQ, etc. qmail-smtpd doesn't know anything
about users. It knows about domains. If a mail is addressed to
anything@acceptable_domain, qmail-smtpd accepts and queues it.

With all of the emails I recieved, I get the impression that I'm going to
I/O bound instead of processor or memory bound. How much disk will be
sufficient for the queue? 1GB? More?
I'm just grasping here to figure out the best solution, so bear with me...
What if I only needed a 1GB queue, and what if that queue was a 1GB ramdisk
(I can put 2GB of ram in the box)? Linux has support for making a disk in
memory, putting a filesystem on it and mounting it. Wouldn't this take care
of I/O problems?

Subject: Re: questions about performance and setup
We're in a similar situation at the moment. However, we want to send out
100,000 UNIQUE emails per day, expanding to 500,000 or more in the near
future. Also, our send window is only actually a couple of hours.
I'm trying to work out the best settings for the concurrencyremote and
conf-split parameters. Our system is a HP Netserver 2000r PIII-667 RAID5
running Linux. Are there any problems in setting conf-split to a very large
value? Is it necessary on a Linux system, assuming a queue size of, say
100,000? Any information appreciated.

Right. One I've was helping a little while ago had 20+ systems
dedicated to the task and they were co-lo'd with plenty of
connectivity. Once you started getting into large scale you need
to consider multiple systems to at least ensure that you have some
sort of redundancy strategy.

The I/O cost is simply there to protect again machine failure, reboots,
power-loss, OS bugs, that sort of thing. Your memory file system will
be ok if it's battery-backed up and running on a system as reliable as
a hard-disk. Otherwise you increase the chances of losing part of your
queue at some point.
Having said that, you may find the trade-off acceptable. That is putting
the queue in a memory file system and accepting a total queue loss once
every now and and again. If eg, it's advertising email and occassional
losses are tolerable, then this may be a perfectly acceptable
cost/reliability trade-off for you.
Regards.
It's all newsletter subscription email so an occasional loss of the queue
would be fine. It won't be pumping out mission critical email or anything
like that. I'm benchmarking a ramdisk filesystem right now, unfortunately
the only thing I have to compare it to is an IDE disk because I can't take
down our other machines to increase the ramdisk size during the day. Even
then, I'd only be able to test on a 10,000 rpm scsi disk, no RAID.

Ahhh... someone who gets it.
> How much disk will be sufficient for the queue? 1GB? More?
What if you did your entire queue injection with your network
connection down? I'd budget for a significant portion of that
plus growth and safety.

I'd read up on ramdisks first. They aren't instant i/o.
Alternatively, Quantum has a line of solid state disks which might do
the trick for you. Pretty pricey, though.

A massive mail injection, especially if the content is unique to the
user, can overwhelm a disk subsystem.
This is reccomending the exact -wrong- kind of disk system. RAID 5
has a write penalty, as it has to calculate parity for each write,
and write to multiple spindles.
The best type of RAID for small block writes is RAID 10 or RAID 1+0
(not to be confused with RAID 0+1). Even better is to use a disk
system with write-back cache. Ideally, you need at least seven
spindles.
I've seen great things with the Infortrend controller.
A great setup would be 1U pc's connected to an external RAID.

Indeed. I haven't played around with ramdisks for a couple of years now, but
last time I benchmarked them, they didn't appear to run much faster than a
harddisk FOR READS as buffer caches on harddisks made them act very
similarly.... Writes would be a different prospect of course...

It's not so much a matter of disk size (I don't think you'll have a 1 gig
queue!), but of throughput. For example, a single IDE drive will get you a
couple of megabytes of throughput per second, at a very high CPU cost. SCSI
will yield more, with a lower CPU utilization, and with RAID arrays, you can
move up to hundreds of megabytes per second if you want to.

That's about as good of I/O as you can get, I would imagine. ; ) As
another author stated, the largest gain would be in writes, but that's where
the largest expenditure is anyway. Just make dang, dang sure that your
machine is NOT going to have any hiccups or lose power while the queue is
full, or you'll instantly lose it all.

Not entirely true. With UDMA mode, modern IDE drives get high
throughput with low CPU utilization. On my Celeron PC, I could get well
over 10MB/sec at well under 20% CPU, and it's hardly performance
hardware (5400RPM spindle). With a 10K RPM spindle and a faster chipset
(mine's a VIA) this will rival or beat fast SCSI disks in raw streaming
bandwidth. However, the majority of mail queues are not even bandwidth
bound -- they're seek bound, which is where SCSI disks still beat IDE.
The faster seek time, the better (which is the motivation behind DJB's
ingenious zeroseek proposal). Also, RAID5 arrays (the most common one
for large capacities) suffer a significant write penalty due to
recalculation and rewiting of the parity, and the mail queue is mostly
written (and subsequently cached). A RAID1+0 array works better, but
uses more disks.

You could quite easily get a 1 Gig queue, even if you don't run into the
obvious problem of temporary loss of network connectivity. Say you've
got 200,000 subscribers and you generate your messages twice as fast
as qmail can send them, then when you've finished generating the
messages you've still got 100,000 in the queue. If the messages are
10Kb each, that's 1 Gb.

What if you put the 2 Gb RAM in the box, but let Linux use it as a disk cache?
I'm not sure how the disk caching under Linux works, but if you create a file
and then delete it before it actually gets written to disk, is there any disk
activity required?
Sure, the disks will be thrashing away, trying to keep up, but would the I/O
actually block if there was still room in the disk cache?

Hi everyone,
Anyone know where there's a list of standard MTA bounce messages? I have
70,000 bounced messages which have been sitting on an imap account and
gathering dust over the past 2 months. My job: to sort these through and
get an approximate picture of which are fake, which are due to relaying
problems, etc.
I've got a script built which goes through each message and based on the
error, will parse it to an appropriate folder: ie ../delete, ../noaction,
../default, ../investigate, etc. From there, I'll be building other
scripts to access the DB to delete members if needed and do other cleansing
actions.
I've been manually going through the email messages and see that all MTA's
seem to produce their own type of error messages and I was wondering if
there's a compiled list anywhere (perhaps I missed the right RFC) for the
most popular MTA bounce messages. This would make life MUCH easier when
doing regex stuff. Anyway, here's what I've got so far:
To delete:
------------
Invalid User
Sorry, I couldn't find any host named dddffgtdddf.comn. (#5.1.2)
Unknown mailbox
Unable to find alias user!
User xunying711 is not found in Server.
The recipient name is not recognized
No Action
-------------
Quota exceed the hard limit
unclassified
---------------
Remote host said: 553 To <[EMAIL PROTECTED]>, message blocked.
Remote host said: 550 <[EMAIL PROTECTED]>: Invalid User
Remote host said: 550 <yujielian29>, No such user.
Also, I noticed that every message directed at 21cn.com domain bounces with
the same error: ie message blocked. What does this signify?
TIA,
Thomas

Hi, I'm using qmail 1.03 on a Debian 2.1 system with the
vchkpw/vpopmail programs. Whenever I try to send mail to
user@localhost, qmail interprets this as [EMAIL PROTECTED],
which is not in the DNS at all. Is there a way to fix this?
"localhost" is the first entry in both my control/locals and
rcpthosts files. This isn't -that- important, I only noticed it
since bigbrother was trying to send emails there, and I found 200
bounced messages in my (postmaster) box over the weekend! :) I can
change this email address, however, I thought I would try to find the
solution to the bug first.

set-up a second pop account for yourself, and in the .qmail file for the
account you have now put:
./Maildir/
&otherpopaddress@server
then qmail will deliver a copy of each message to each box, then check one
only at home, and one only at work...

those options are for the configuration script. you may want to re-read

./configure [with your options, like --enable-roaming-users=y]

Here is what I do to test a new virtual domain:
1) create the domain
~vpopmail/bin/vadddomain test.com test
2) Send email to the postmaster user
echo "to: [EMAIL PROTECTED]" | /var/qmail/bin/qmail-inject
3) authenticate with pop
telnet 127.0.0.1 110
user [EMAIL PROTECTED]
pass test
list
You should see one message listed.
Then it works

Man, don't even worry about parsing all those different bounces.
Another poor soul on this list has said he needs to parse 70,000 or so
of them--that sounds awfully painful.
Use the method that djb pioneered to handle bounces: VERP. Details at
http://cr.yp.to/proto/verp.txt. Set QMAILINJECT="r" in your
environment when sending the mail to generate VERP return paths (see
the return path of this list message to see what VERP does to the

Actually, qmail is not "reliable" on any Linux FS. This was discussed
to death a while back. It is DJB's view that all directory operations
(creating, removing, linking, etc.) sould be synchronous, just like BSD
does. It is Linus' view that this is a significant performance penalty
with little gain, since applications that require synchronous directory
operations also tend to require synchronous file operations and other
special file handling. I agree.
There is also the discussion of ordered meta-data updates (OMDU) vs
unordered (UMDU). Linux (with the exception of newer journalled file
systems) does UMDU. With OMDU, the file meta-data (inode, indirect
blocks, etc) is written in an ordered fashion, typically before the
data. This means FWIR that you can have good meta-data pointing to bad
data in the case of a crash. With UMDU, you can have bad meta-data but
good data, which is something that a fsck will detect.
Since crashes are so rare, and journalling file systems becoming more
populous, this is rapidly becoming a non-issue.
I wrote a source file that replaces libc's open, link, rename, and
unlink routines with my own that sync the appropriate directory after
executing the syscall but before completing. Simply linking with it
causes all directory operations executed by the program to become
synchronous.
It is available at http://em.ca/~bruceg/syncdir/ I include it in my
patched qmail RPMs.

For the record, FFS with soft-updates does not guarantee synchronous
directory operations; you have to open and fsync() the file you just
moved to be sure the operation has been committed to disk. See
http://mail-index.netbsd.org/current-users/2000/06/19/0011.html for a
little more information.
Based on the patch, it sounds like ReiserFS agrees with
FFS+softupdates in semantics; that is, if you want to ensure that a
directory operation has completed, you open and fsync the directory
entry you care about. This behavior is different from ext2fs, where
you have to open and fsync the directory containing the entry you care
about.

Then I was confused. I assumed FFS was like UFS on Solaris, where you
can "feel" the synchronous directory operations by doing a "rm -rf" of
anything larger than a few files.

But qmail already does this. In fact, it is very careful to do this in
all the places it is necessary. If ReiserFS behaved identically to
FFS+softupdates, it would not need any qmail patches. (I have deleted
the original message which we are discussing, and I don't remember what
exactly it patched)

Which to me seems to be a more logical mode of operations: if you want
the file data sync'd to disk, call fsync on the file; if you want the
directory, fsync the directory.

You have ODMU backwards. Any sane ordered write scheme will write out
a block X before writing out a block (inode or directory entry) which
points to block X. FFS, with or without soft updates, should never
encounter a case where an inode points to bad data. (Of course, if
you disk controller reorders write operations you'll lose no matter
what. Unfortunately, you have to choose both your hardware and your
software somewhat carefully if you really care about filsystem
consistency.)
Linux ext2fs has no write ordering whatsoever. If the system goes
down uncleanly, you can get metadata pointing to bad data or data not
pointed to by metadata. A recently created file might exist but
contain blocks from an old copy of /etc/shadow instead of the data you
wrote to it. It's really ugly. fsck cannot correct all of the
possible problems which can arise, no matter how clever or thorough it
is. People have tried to justify this state of affairs in lots of
ways, but the only potentially correct and convincing justification
is, "who cares?" Which is great unless you're one of the (admittedly,
relatively few) people who does care.
Note that write ordering is different from synchronous
vs. asynchronous operations. Write ordering is about filesystem
consistency, which is mostly irrelevant to qmail's operation because
of the way qmail works. ext2fs is also a little odd with respect to
synchronous operations (as discussed in my last piece of mail), but
it's certainly possible to work around that.
The 'sane' response would be to buy high-end power protection equipment
and use redundant drive configurations (RAID) and only worry about whether
the kernel writes out data consistently or not (and good journalling takes
care of many performance issues here).
Reliability of gigabytes per minute of data is not just a case of
demanding synchronous writes (which is silly in many cases). Power faults
can be protected against as can many cases of hardware failure.
Performance should not be sacrificed for the cases where someone has a
high case of failure potential (high being relative).

Soft updates are a recent thing. UFS on Solaris does not have them.
Without soft updates, FFS does have synchronous directory operations,
and yes, you will feel the resultant performance limitations.

I can't really address this issue; I don't know qmail well enough.

Perhaps. There are arguments for either model being simplest, and
history should not be ignored when picking between the two. The
Single Unix Spec v2 also appears to mandate the FFS model, for those
who care about that standard:
The fsync() function forces all currently queued I/O
operations associated with the file indicated by file
descriptor fildes to the synchronised I/O completion
state. All I/O operations are completed as defined for
synchronised I/O file integrity completion.
[and:]
synchronised I/O file integrity completion - Identical to a
synchronised I/O data integrity completion with the addition
that all file attributes relative to the I/O operation
(including access time, modification time, status change time)
will be successfully transferred prior to returning to the
calling process.
[and:]
synchronised I/O data integrity completion - [...] The write
is complete only when the data specified in the write request
is successfully transferred and all file system information
required to retrieve the data is successfully transferred.

I didn't say simplest. It's a little more complicated to have to
remember to sync the directory as well as the file.

Exactly the point that Linus has made about this (and many other issues)
before.

Hello,
I want to write a simple script to check if
mails are queued in /var/qmail/alias/pppdir/new
to decide, wheter the PC should go online or not.
Is there a spezial command like 'qmail-queue' to
decide if the computer should dial (isdn) to the
provider and send the queued mails using maildirsmtp?
Of cource, I can check this with
# if ls var/qmail/alias/pppdir/new then;
but maybe there is an other way?
Thanks

Most mail packages have the ability to let a user log in when sending mail.
(Outlook for example.) I was looking at this and had a couple of
questions...
Is this part of the SMTP standard?
Can this be used to let authorised people relay through a server?
Thanks

There are mods to qmail that allow users who have been
authenticated through pop to then send out mail
through your SMTP server. I have no experience with
this, but I remember seeing it on www.qmail.org.

It is not part of the original rfc821, but it's documented in a "standard"
document from last year:
It's often called "SMTP AUTH".
http://rfc2554.x42.com/
2554 SMTP Service Extension for Authentication. J. Myers. March 1999.

Yes.
Look for "Mrs. Brisby" and "Krzysztof Dabrowski" on www.qmail.org.

If you search on "filter" http://on www.qmail.org/
then you'll find at least two packages for this.
You can do simple filtering with perl and .qmail-files.
Tips:
* procmail supports Maildir
* MrSam:s maildrop works nice with Maildir
http://www.flounder.net/~mrsam/maildrop/
* mailagent (Perl)
http://search.cpan.org/search?dist=mailagent
* Kagent (Perl)

What do you mean by ``for one user''? Do you mean you share a POP
mailbox with someone else and you want to tell whether a message
was for you or that someone else? Or do you simply mean that you
want to filter depending on where the message is _from_?
In the former case, fetchmail has a multidrop mode; read the manual
page, fetchmail(1), for more info.
In the latter case, look into procmail; qmail has a script that
delivers mail through procmail by default at /var/qmail/boot/proc+df.
All the help you need in writing the filters are in the procmailrc(5)
and procmailex(5) man pages.
If you're delivering to a Maildir, as you suggested above, make sure
that the folder specified in the procmail recipe ends with a slash.

Hi,
Is there a way of keeping a local copy of the RBL lists and using those
instead of trying to get it from the remote site - should this not speed
things up - I also know that the list is updated all the time - but can
some of you peoples please comment...
Thanks

Hello,
I've searched the archives on this topic and though there are a lot of
people who have reported this issue, I have not really seen a solution yet.
I have a Linux box (Redhad 5.?) which I use as a firewall/server/NAT
machine. One ethernet card is connected to an ADSL modem and has a fixed IP
address. The other ethernet card is connected to a mini-hub and has the
address of 192.168.1.1. I have a set of Mac's connected to the hub with
addresses 192.168.1.100 and up.
I've got Qmail running just great for both SMTP and POP!! However, as soon
as I activate my firewall (using ipchains), sending or receiving email from
a local machine takes over 3 minutes!!
In the archives, some people have speculated that this is a DNS issue or a
problem with auth. I have TCP port 113 (auth) opened to the world (local
and internet) and am still having a problem. I suspect that there must be
some other port I need to open up. Does anyone have a suggestion of where I
can go from here? I am a bit new to Qmail and not too familiar with the
debugging tools.
By the way, I do not have DNS active on my Linux box and am relying on my
ISP's DNS server (they have my domain name set up in their server).

Hi,
I must be missing something: I want to have an alternative aliases
file to be used by a user controlling a few virtual domains.
I know how I would _use_ such a file:
$cat ~user/.qmail-default
|fastforward -d ./alternative-aliases.cdb
$
The question is: How do I _create_ such a file? According to the
manpage, newaliases has /etc/aliases hardcoded in it. What's the
alternative? (Except, of course, creating the file as /etc/aliases.cdb
and then moving it somewhere; I don't want to give that used write
permissions into /etc, obviously.)
Thanks

hello list
i have installed redhat linux 6.1 , with sendmail 8.9.3 from rpms
(redhat cd)
i want to remove sendmail and install qmail on this system ,
please tell me exactly how can i do this
thanks & regards
Prashant Desai
OK, first - untar or install the qmail files. THEN read REMOVE.sendmail and
then if you have any further questions, ask on the list. The docs are
usually a good place to start, as 95% of these questions are answered
there...

Hi,
I noticed the ftp location for the updated (to 1.03) anti-spam
patches from Ras/Lionel/Lindsay doesn't allow anon access
anymore (it's a buggy wu-ftpd version ?). Anyway, can anyone
point me to a new location, update the web site, or send me a
copy ?
Thanks,
