bounceroute? -- how to offload bounces
Howdy, all. Our outbound mail server spends the vast majority of its resources (attempting to) bounce mail (usually from spam :( ). The result is that sometimes, when load is very heavy, normal outbound deliveries sit in the queue and wait a while. So... I'd like to set up a dedicated machine to handle bounces. The bounce* and doublebounce* control files don't appear to be useful here. And I don't see how I can garner the help of smtproutes, either. What I really want is the following logic: "A message needs to be bounced? Relay it first to 192.168.N.N and let him handle it." Thanks in advance for any suggestions! Dave

RE: Requesting the services of Hercule Poirrot
However, when I ran qmail-qstat, it showed ~3300 messages in the queue (normally this is closer to 400). In the past, this has indicated an onslaught on spam. But if resources are available, and smtp and local have concurrency available, I don't understand why ANY incoming message would not show up in someone's mailbox promptly. I don't either. Did you try injecting a message and tracking it through the logs? You need to identify where they're lingering. No, I did not try in enough detail. Do you recommend injecting from a remote qmail machine? That would allow me to track the individual message's delivery from the remote qmail's maillog, since it may never make it to the local server... And have you check your trigger? I'm fearful of running "make check" because it depends on "install", and this is a live system. However, the trigger shows: prw--w--w- 1 qmails qmail 0 Sep 1 10:40 trigger (and the system seems to be fine now without any modification). So, unless there are any other ideas, I guess I'll just have to try to track an injection next time around, eh? Thanks very much! Dave K :)
SOLVED: so much qmail-smtpd activity, so little qmail-send activity...
I used recordio with qmail-smtpd to trace some smtp dialogs, and found some results that you qmail-philes might find useful. For some reason, I had trouble extracting this info by looking at the source code. Useful qmail-smtpd exit codes: 256 = bare linefeed problem (http://cr.yp.to/docs/smtplf.html) 25600 = tcpserver denial (probably invalid IP) I hope this helps others of y'all. Incidentally, if there are THAT many 256's showing up in our logs, I wonder if, rather than taking it as a Hard error, the remote smtp server is treating it as a deferral, and continuing to retry repeatedly...

RE: Requesting the services of Hercule Poirrot
Do you recommend injecting from a remote qmail machine? That would allow me to track the individual message's delivery from the remote qmail's maillog, since it may never make it to the local server... Hmm, I didn't think there was any question that messages were being queued and the delays were after that point. Am I missing something? I did not know if the messages were queued yet or not. That is why I also checked that qmail-smtpd had enough concurrencies to spare. But that raises a good point: when I trace my message next time around, I'll be sure to see if it's already in the queue, but stuck there for some reason. Dave K
RE: Requesting the services of Hercule Poirrot
That figure means they're not delivered yet, either locally or remotely. It usually just means that the messages are deferring, either because the remote server is down or something else "normal".

Envelope Recipient from environment?
Hey folks, We have access to the envelope sender in $SENDER, but qmail munges the envelope recipient via virtualdomains, resulting in $RECIPIENT which is not a valid email address. We all know that you can calculate the envelope recipient by taking $RECIPIENT and removing $HOST from the beginning, or else parsing the To:, Cc:, and Bcc: headers by hand. But considering the flexibility provided in qmail-command, it seems to me rather odd that I don't have access to what might be considered the most primitive property, the envelope recipient, without jumping through some hoops. Am I missing something? I guess some of you might use $EXT@$HOST if you have wildcard entries in assign; we have a separate alias entry for each recipient in assign... Thanks y'all, Dave

You might start isolating the problem by removing the " echo -n '

RE: Multi-RCPT vs. Single RCPT delivery - logic error?

Multi-RCPT vs. Single RCPT delivery - logic error?
Regarding: http://web.infoave.net/~dsill/lwq.html#multi-rcpt Dave S, I'm having trouble accepting this logic. You mention 3 options: "Say you're an MTA, and one of your users sends a message to three people on hostx.example.com. There are several ways you could do this. 1. You could open an SMTP connection to hostx, send a copy of the message to the first user, send a copy to the second user, send a copy to the third user, then close the connection. 2. You could start three processes, each of which opens an SMTP connection to hostx, sends a copy of the message to one of the users, then closes the connection. 3. You could open an SMTP connection to host, send a copy of the message addressed to all three users, then close the connection. " and that qmail uses option #2. Clearly, the rank of efficiency is, from best to worst,: 3, 1, 2 -- We had a situation with a customer who was consulting for a college. So every few days, she had to send a 10MB PowerPoint file to about 50 recipients at that college. Under qmail, a separate thread was opened up for each qmail-remote. a) That means a total transfer of 500MB rather than simply 10MB. b) Secondly, since all outbound threads were tied up for a long time, all other mail was deferring, causing customer complaints. c) Finally, since all 50 messages were being received by the same remote SMTP server, the transfer was bottlenecked by the cpu and i/o of their single mail relay trying to receive 50 copies of the same thing. We love qmail, and it's working very well for us in general. But I'm having a hard time reconciling your logic in this paragraph. Perhaps you could clarify for me. Dave (K)

We are switching to all Cisco Pix firewalls which, unlike our previous firewalls, all appear to have the IDENT port blocked. Fine, so I put the "-R" option in my qmail tcpservers, and we're happy again, with no more 26-second delays. The man pages say qmail-smtpd required $TCPREMOTEINFO, but it doesn't say how it uses it. Will it show up in the headers somewhere? Is that were the Received-By header gets the IP-name translation? We want to make an informed decision, and to do so we need to understand how it will impact qmail. Thanks in advance! Dave :) _ From Bernstein: http://cr.yp.to/ucspi-tcp/environment.html $TCPREMOTEINFO is a connection-specific string supplied by the remote host via the 931/1413/IDENT/TAP protocol. If no information is available, $TCPREMOTEINFO is not set. Beware that $TCPREMOTEINFO can contain arbitrary characters. From RFC 1413 "Identification Protocol": http://andrew2.andrew.cmu.edu/rfc/rfc1413.html Excerpts: "The Identification Protocol (a.k.a., "ident", a.k.a., "the Ident Protocol") provides a means to determine the identity of a user of a particular TCP connection. Given a TCP port number pair, it returns a character string which identifies the owner of that connection on the server's system. The Identification Protocol was formerly called the Authentication Server Protocol" "Security Considerations The information returned by this protocol is at most as trustworthy as the host providing it OR the organization operating the host. For example, a PC in an open lab has few if any controls on it to prevent a user from having this protocol return any identifier the user wants. Likewise, if the host has been compromised the information returned may be completely erroneous and misleading. The Identification Protocol is not intended as an authorization or access control protocol. At best, it provides some additional auditing information with respect to TCP connections. At worst, it can provide misleading, incorrect, or maliciously incorrect information. The use of the information returned by this protocol for other than auditing is strongly discouraged. Specifically, using Identification Protocol information to make access control decisions - either as the primary method (i.e., no other checks) or as an adjunct to other methods may result in a weakening of normal host security. An Identification server may reveal information about users, entities, objects or processes which might normally be considered private. An Identification server provides service which is a rough analog of the CallerID services provided by some phone companies and many of the same privacy considerations and arguments that apply to the CallerID service apply to Identification. If you wouldn't run a "finger" server due to privacy considerations you may not want to run this protocol. " Other: The Ident port is Port 113.
RE: Impact on qmail of no $TCPREMOTEINFO / IDENT ?
Thanks for the reply. The man pages say qmail-smtpd required $TCPREMOTEINFO, but it doesn't Really? Where? I didn't see that and the code in qmail-smtpd.c suggests that it's optional. Hmm. Well, the qmail-smtpd man page says: "... qmail-smtpd must be supplied several environment variables; see tcp-environ(5)..." and the man for tcp-environ lists TCPREMOTEINFO: http://www.qmail.org/man/man5/tcp-environ.html It doesn't hurt to get it and log it, And how would one do that? Does it show up when you run qmail-smtpd with tcpserver's -v option? In an SMTP relay environment, such as an ISP or a corporate outbound system where most people send from a desktop, via a local server to you, it's mostly not of use (that's not to say that it couldn't be useful just that it's not typically implemented to be so). I see. Well, we're an ISP, and remember that while half our SMTP mail (outbound mail) comes from desktops like you said, the other half (ie, incoming mail) comes from other SMTP relays around the world. I'm open for more input. Can anyone else comment on how else a blank $TCPREMOTEINFO will affect our qmail logs, headers, etc? Dave
RE: Understanding To and From
Yes, Charles, I'm pretty darn happy at this point. Thank you both, Charles and Claus. So here's what I think you're saying. 1) The To: and From: headers are basically completely forgeable, and can't be trusted for tracing spam (along with Reply-To). 2) The only things that matter are the envelope sender and recipient, and qmail stores these as Return-Path: and Delivered-To:, respectively. And Return-Path: can be forged anyway. - Looking at INTERNALS, qmail appears to store the envelope sender under queue/info and the recipients under queue/local and queue/remote, eh? 3) So the only thing I can trust (ignoring spoofing) is the IP address shown in the Received: header from which my server got the message.

Understanding To and From
Hi, folks.
It's time for me to understand this stuff clearly once and for all,
partly so that I can handle spam intelligently and properly.
I'm unclear on the exact relationships between the following:
---
1) MUA: "From", "To", "Bcc", "Reply Address" fields
2) SMTP: "MAIL FROM:" and "RCPT TO:"
3) Delivered Message: "To:", "From:", "Reply-To:", "Return-Path:"
headers. Also, the terms "envelope sender" and "envelope recipient".
4)Bounced Message: "To:" header
---
From what I currently understand, the MUA fields are (obviously)
completed by the sender. (Let's assume a common client like Eudora or
Outlook Express rather than qmail-inject for this discussion).
When connecting to the SMTP server to send the message, the "From" and
"To" fields are copied by the MUA to become the "From:" and "To:"
headers of the message. The "From" field is also used in the SMTP
conversation as the "MAIL FROM:". Then, all addresses in the "To",
("Cc",) and "Bcc" fields are used as SMTP "RCPT TO:" entries.
- Question: Are "Bcc" recipients not stored anywhere in the headers, or
are they stored in the headers until the message is ready to be
delivered into the recipients box, and then stripped off? (If they are
NOT stored in the headers, where does qmail store them?)
The "Reply-To" header is created by the MUA from either the "Reply
Address" field, if present, or else the "From" field. The "Return-Path:"
header is added by the SMTP server based on the "Reply-To" or "From"
header (?)
- Question: So, now what do we look at to determine the "envelope
sender" and "envelope recipient"? Secondly, which of these terms/headers
is used to determine whom qmail delivers the message to?
Okay, now the message bounces because because it's an evil spam message.
- Question: Where does MAILER-DAEMON send the bounce message? To the
"From:" person? "Reply-To:"?
If I could understand THIS much, I'd be very happy.

buggy interaction with VisualMail

But when using qmail as the smtp server for VM, AND subsequently reading the mail in VM, there are two problems: 1) Date corruption 2) Missing messages I've approached mintersoft regarding this, but I'm not optimistic that they will be both willing and able to fix it. So, I'm looking for workarounds. I'm assuming that the date problem is caused either by qmail using GMT or else by VM possibly neglecting to add the "Date:" header. What's the best way to pin down the cause of the ploblem, and then how to fix it?

Again, what's the best way to pin down the cause of the ploblem, and then how to fix it? Is it to reroute through qmail-inject, as per: http://cr.yp.to/qmail/faq/servers.html#network-rewriting ?

forwarding terminology?
We have been using the term "mail forwarding" with our customers in the same way that the USPS uses it: when your mail arrives at your mailbox, it is "redirected" to a remote location (via a "" entry in .qmail). However, we have been told by a somewhat educated customer that this process is really called "moving", not forwarding. "Forwarding", they say, means that a copy is saved locally (via a "./Maildir/" entry in .qmail) and a second copy is transmitted to the forwarding address. What is the correct terminology? How do most of you use the term "forwarding"? Thanks for your input! Dave NetCarrier

RE: Eudora? Outlook?
Yes, Netscape is a problem, even in the new versions. You would think you could turn off the "smart @" interpretation, but I don't think you can. Netscape always assumes you were mistaken when you included the "@", and strips off the rest. We decided to use pop ids such as: joe-domain.com instead of [EMAIL PROTECTED] Good ol' "double-dash". Almost any special character is asking for trouble.

fixcr left hanging
Greetings folks, Ever since I implemented the "fixcr" addition to "smtpd", I've noticed that over time my qmail servers accumulate a large number (several dozen) pairs of processes: "fixcr" and "sh -c fixcr | /usr/qmail/bin/qmail-smtpd". -- ps -alxww UID PID PPID CPU PRI NI VSZ RSS WCHAN STAT TT TIME COMMAND 1002 45088 88130 0 10 0 496 244 wait I ??0:00.00 sh -c fixcr | /usr/qmail/bin/qmail-smtpd 1002 45105 45088 0 2 0 752 380 sbwait S ??0:00.08 fixcr ... 88130 p1- S 2:06.75 tcpserver -c 600 -x /etc/tcp.smtp.cdb -u 1002 -g 1001 0 smtp sh -c fixcr | /usr/qmail/bin/qmail-smtpd -- When I kill -9 a "fixcr" process, it ends the corresponding "sh -c fixcr | /usr/qmail/bin/qmail-smtpd" process, which makes it appear that for some reason "fixcr" is having trouble exiting cleanly. Other than an occasional "killall -9 fixcr" that I have to run, it doesn't seem to cause any problems except for concern by the mail administrator (me :) that something isn't configured properly. Speaking of configuration, here's what I use: tcpserver -c 600 -x /etc/tcp.smtp.cdb \ -u `id -u qmaild` -g `id -g qmaild` 0 smtp \ sh -c 'fixcr | /usr/qmail/bin/qmail-smtpd' Any suggestions? Thanks!

Industry name for various email services? (repost)
What are the industry-standard names for the following email services: -- 1) They can have: any_name@their_domain and a separate POP for each. (.qmail-any_name) -- 2) They can have: any_name@their_domain but they get only a single pop account, "default", for retrieval of all the mail (.qmail-default). -- 3) All mail to any_name@their_domain_2 is treated as any_name@their_domain_1 (by virtualdomains entry: their_domain_2:their_domain_1) -- We've been calling these variously "Full Domain email", "POP domain email", "Alias Domain email", etc. But I want to know what the *real* names are for these.

q in qmail means ?
I ask this question with great trepidation. Either I'm the only one brave enough to ask, or I'm the only one stupid enough to have to ask, but... What does the "q" in "qmail" mean? Dave p.s. Since I'm going to get flamed for stupidity, let me ask another question: If LWQ insists that the official name is "qmail", not "Qmail", why does the logo start with "Q" on http://www.qmail.org/top.html?

RE: New qmail list et al

You could also probably use a foreach loop in csh to use each file in the maildir directory as input to qmail-inject with a specified recipient.

I had the same problem once. Assuming you have access to an FTP Proxy server, enable it in your web browser.

purging spam - here's what's working for me
The following script seems to have worked for me. Note that you don't
"touch" the "mess" file under ./queue/ but the corresponding "info" file,
as per FAQ 7.3.
Checking the log, messages appear to be SLOWLY retrying, and then expiring
with the message:
Jun 24 15:17:38 bsdpop qmail: 930251858.063072 delivery 523142: failure:

I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/I'm_not_going_to
_try_aga
in;_this_message_has_been_in_the_queue_too_long./
and the qmail-qstat is going down, although gradually.
Let me know if this is helpful or can be improved.
Dave
p.s. I created this script today to purge out a bunch of spam from the same
domain; so, it searches the "From:" line. This might have to change for
other spammers.

RE: $ to do this? Re: Concept: 'infinate' POP3 accounts per pop3 user.
I missed the beginning of this thread, so pardon this if it's moot. But I couldn't help noticing that someone wants to use '[EMAIL PROTECTED]' as POP authentication ids. I tried to do this and ran into a serious problem: Netscape Mail chokes on the "@". It assumes you mistakenly entered your email address when you really meant to put your POP id. So it converts it to, in your example, '[EMAIL PROTECTED]', chopping off the '@theirname.domain.com' part. So we chose to avoid the "@". If my C skills were more proficient or I had more time, I'd still keep it as "@" internally but hack checkpassword so that Netscape users only could use an alternate character, such as "%" (thanks, Paul). Dave ... Essentially I'm thinking of enabling the user to login via POP3 as '[EMAIL PROTECTED]' with their normal password. (I've written the checkpasswd so it's easy to authenticate ok). ...
Holiday messaging: preventing loops?
I developed a script to support holiday messages. It appears to work very nicely with one important exception (that I expected): if a person on holiday sends a message to another person on holiday, they get an infinite loop of holiday notifications to each other (thank God for quota enforcement!) Anyway, below is the guts of my script, which is pretty basic. So my question to y'all is, what logic do other "holiday" algorithms employ to prevent such looping? Could I make a more judicial choice of environment variables to use for the sender and recipient? (I went to some length in research to configure things so that a holiday message could be properly "replied" to, but perhaps disabling this is inevitable?) Thanks in advance! Dave - #!/bin/sh # # holiday.sh # # Dave Kitabjian, 6/11/99 # [EMAIL PROTECTED] # # This script should be entered into a user's .qmail file as |holiday.sh # It depends on the SENDER environment variable, provided by qmail-local; # HOME and HOST are also used. # It permits delivery and replies with a message found in .holiday # # Should be able to use $USER @ $HOST, but we using a single-uid # configuration of Qmail.
