Re: deliver.db to big size.

[Anthony Tibbs (Trinimex)]

Manuel,

If I'm not mistaken, "deliver.db" is used exclusively for duplicate 
message suppression.  I can't imagine why it has grown so big (unless 
you are not running "ctl_deliver -E" regularly -- normally this is 
configured to run every 24 hours or so in /etc/cyrus.conf).


Some people keep "deliver.db" on a ramdisk/tmpfs, so my take is you can 
safely delete that file and start afresh without any real consequences.  
But check to see that "ctl_deliver" is running to prune the duplicates 
database too...

Testing: Exim, Cyrus and invalid header lines

[Anthony Tibbs (Trinimex)]

Hi folks,

This is, at present, only a test message.  I am setting up a new box 
with Cyrus and Exim, but my experience has always been with Postfix.  
For some reason, messages from the Info-Cyrus list -- and so far, ONLY 
messages from the Info-Cyrus list -- are being rejected by Cyrus LMTP as 
having an invalid header.  Now testing to see what the cause is.


I've managed to get Exim to strip blank Message-ID: headers, which I 
know Cyrus doesn't like much, but I'm not sure that is it.


Why does Cyrus have to be so fussy?

(Watch, this message will come back to me just fine.)

Re: SSL certificates

[Anthony Tibbs]

Kevin,

I wondered about the passphrase myself.  The instructions GoDaddy 
provides are, of course, tailored for Apache, and maybe they think 
entering a passphrase is a reasonable thing to have to do, though I 
can't imagine what server admin would actually want that.

I'll dump the passphrase and try again.  I would bet that is the culprit...

SSL certificates

[Anthony Tibbs]

Good morning,

I've been running Cyrus at a couple of small sites since 2001 or so.  
I've run into a snag trying to setup SSL using something other than the 
self-signed, auto-generated certificate.  The domain has a GoDaddy 
2048-bit SSL certificate.  From the SSL manager, one downloads a bundle 
that contains a certificate chain bundle, and a separate file with the 
certificate for the domain itself.


The key and CSR was generated with:

openssl genrsa -des3 -out xxx.key 2048
openssl req -new -key xxx.key -out xxx.csr

I've seen a few different methodologies posted about how to install 
this.  One is to conctenate the domain certificate, the certificate 
chain, and the private key into one .pem file and set tls_cert_file, 
tls_ca_file, and tls_key_file to point to the same '.pem' file.  Another 
is to keep the files completely separate.


No matter what I have tried, I've been unsuccessful.  Thunderbird 
reports that it received an SSL record that is too long, and/or the 
imapd process becomes stuck at 100% CPU utilization until it is killed 
forcibly.


Is there something I'm missing on this?

Re: Exec'ing a script from Cyrus when imapd has a client

[Anthony Tibbs]

You know, I don't know if I agree with all the objections over this person's 
request.  I actually have a similar setup where Fetchmail is used to 
retrieve messages from a remote mailbox for injection into a Cyrus setup, 
primarily because of quota requirements on the far end.  Yes, modern MUA's 
offer the ability to store messages locally, but what if you have that MUA 
installed in several computers in different locations?  Moving to 'local 
folders' in that case isn't helpful.  And yes, you could setup two 
accounts - one on the main server and one to your cyrus setup - and move 
messages manually, but then why not fetchmail to the cyrus setup directly 
too?

ctl_cyrusdb I/O requirements

[Anthony Tibbs]

Hi everyone,

I'm running Cyrus 2.3.14 on a VPS (Gentoo), and have been for a number 
of years now.  All was well until last night when performance went down 
the tubes and I started seeing high I/O wait times.  I'm pretty sure 
this is a problem on the hosting end, but in trying to diagnose the 
source of the I/O congestion, the closest I could come to answer was 
that ctl_cyrusdb is reading/writing about 15-20 4096b blocks (from the 
/var/imap/db/* files) per second.This amounts to read/write 
throughput in the 250kb/second range. 

Is this "normal" behaviour?  I never noticed before, but it's the only 
thing I see that is constantly generating I/O...


Take care,
Anthony

Re: Cyrus APIs ? - detecting new messages in a folder

[Anthony Tibbs]

This might seem like a really dumb question, but why can't you just 
monitor the log file for Delivered: lines and parse those (as they 
appear) to do the 'push'ing? 

I have a script that monitors this and gives me the datestamp, 
user/folder, and Message-ID domain on a running basis. 

Or am I missing something really obvious here?

Re: Logging number of pop3's email retrieved during a connection - was (IMAP/POP traffic accounting)

[Anthony Tibbs]

Hi Eddy,

I had worked on this briefly and, given a day or so, I could probably come 
up with a working solution at least for byte/traffic accounting.  Logging 
'messages retrieved' for POP3 could make some sense, but it gets complicated 
with clients using "TOP" to partially retrieve messages for inspection, and 
in the IMAP world its all but meaningless (since that might involve copies 
to folders, etc.).

For pure traffic accounting purposes, though, that isn't so hard, 
particularly if you don't want it saved in a database anywhere, but merely 
added as a log entry.

I might not have a chance to look at this until December though. 
Cyrus/software development is something of a side job for me, as I'm 
actually a third year student in McGill's Faculty of Law.  But I will work 
on getting this done (since I need it nowadays anyway) for traffic 
accounting on IMAP/POP3 at the very least...

Take care,
Anthony

Re: Method to drop unknown user messages to black hole

[Anthony Tibbs]

Hi Bob,

Perhaps I am missing something here, but with my Postfix setup (which is based 
on two instances of Postfix + amavisd-new + Cyrus), messages are checked 
against a user database at the outer postfix, and rejected during the SMTP 
connection for invalid recipients, before lmtp/etc. even sees it.  For me, this 
requires that user logins/authentication be handled through a MySQL database, 
but is this an option for you?  

It avoids almost all of the backscatter issues... though may not be the best 
setup for everyone.

Take care,
Anthony

  Subject: Method to drop unknown user messages to black hole


  Postfix & Cyrus

  Have been finishing off the server ready for accepting external smtp
  connections. No more fetchmail...

  I note that in todays spam environment more and more administrators are
  choosing to black hole any messages with invalid recipients. In a
  standard postfix setup this is pretty easy with luser_relay. When
  however you use lmtp, local delivery really only looks at /etc/aliases
  until it passes through to cyrus.

  My first question is a general one. Do you all choose to send
  reject/nonexistent user messages or just black hole them? Rejecting is
  obviously the simplest solution but I am concerned about being
  blacklisted from sending garbage back out. There are ways of course to
  stop backscatter happening but I am also concerned that there are valid
  bounces being created that the (real) sender needs to know about. I'd
  like to hear what your solutions have been.

  My second question is how to you accomplish a black hole with cyrus? I
  had thought that a "global" sieve script would do it but note that this
  is user specific. I see nothing specific in lmtp that points to that either.

  I note this has been discussed previously but I didn't find an actual
  resolution beyond allowing auto mailbox creation!

  Thoughts appreciated

Outlook Express and IMAP connections - thousands of them?

[Anthony Tibbs]

Hi everyone,

I've been using Outlook Express with Cyrus now for several years (since 
2002), have set it up on many different computers, and have never run into 
this before.  I have one user who is also using OE, and their OE is doing 
something very strange - it's disconnecting and reconnecting for every 
folder it checks, leading to (litreally) thousands of lines a day indicating 
a new login:


Dec 14 12:02:25 polaris imap[26772]: login: clientHost [69.xxx.xxx.xxx] 
@tibbs.ca plaintext User logged in
Dec 14 12:02:25 polaris imap[26170]: login: clientHost [69.xxx.xxx.xxx]

Dec 14 12:02:27 polaris imap[26772]: login: clientHost [69.xxx.xxx.xxx]

... and so on.  Looking at the telemetry logs, there doesn't seem to be 
anything "unusual," or any errors or anything (see below).


Is there a setting somewhre that I don't know aobut that would affect this?

IMAP/POP traffic accounting

[Anthony Tibbs]

I believe there was some mention of this in the past, but I'm wondering 
whether there are any known efforts to implement network traffic accounting 
in the later versions of Cyrus, or if this is still something that hasn't 
been dealt with.  I am pondering possibly tackling this, but I'm not really 
familiar with the Cyrus code and would rather not reinvent the wheel if it's 
already in the works.


On the surface, this appears to be fairly straight forward, what with the 
protocol abstraction already in place (where recording could be done at or 
around the same place as telemetry logging) ... or is there something I'm 
missing about this idea that makes it significantly more complicated than it 
first appears?

It doesn't check for things like the user already having a Spam mailboox,

Sendmail aliases and Cyrus

[Anthony Tibbs]

Hi everyone,

I was trying to check the list archives for some hints, but it seems that 
that server is having some 'difficulties' at the moment, and isn't 
responding.


I am currently in the process of setting up another Cyrus/IMAP server, as 
I've been (personally) running Cyrus/Sendmail for a few years now with good 
results.  I had the usual sendmail+virtdomains+cyrus hoops to jump through, 
but now have THAT working all right (by way of a mailertable entries, i.e.


mydomain.cacyrusv2d:/var/lib/imap/socket/lmtp

The problem is that for this to WORK, mydomain.ca must not be considered a 
"local domain" (i.e. it must not be in local-host-names), since this results 
in a rewrite that strips the 'host' portion of the address off, and then 
Cyrus rejects the message with an 'unknown mailbox' error.


And all of this ultimately means that I can't use sendmail "aliases" (for 
non-local addresses), which I need in order to redirect such things as 
postmaster, root, etc. to a particular user.


Have I missed something simple here?  I've tried following the instructions 
at http://asg.web.cmu.edu/cyrus/download/imapd/install-virtdomains.html but 
that is where I am getting stuck...

Re: Question about cyrus quotas - how it behaves

[Anthony Tibbs]

Check out quotawarn: and quotawarnkb: in man imapd.conf.  They result in 
IMAP ALERT messages being generated.
Note that these alerts are sent on SELECT, and it has been claimed that 
Outlook SELECTs a lot, making it unusable. I have not verified this.
Indeed, this can be a problem if you have a large number of folders.  For 
example, I have about 30 folders under my Inbox for archived messages, 
various mailing lists, etc., and if I ever get near the quota, hitting 
Control+M to poll for messages is a really bad idea, because I'll get an 
alert dialog at least once for each and every folder -- and there's nothing 
you can do but keep hitting ENTER until it is done.

It can be annoying, but I'd wager that most people don't sit above that 90% 
threshold for long, before they clue in and dump some old mail.

Re: Virtual host help - users on virtual domains can't authenticate

[Anthony Tibbs]

What command did you use to add the user to the saslpasswd2 database?  It 
should be something like this I believe...

saslpasswd2 -u domain2.com -c user
(At least for me, adding them as saslpasswd -c [EMAIL PROTECTED] didn't 
work.)

- Original Message - 
From: "Sun Advocate Webmaster" <[EMAIL PROTECTED]>


I have cyrus authenticating via sasldb, and all works well for local 
domains. However, "virtual" domains don't work.

My DNS for all the "virtual" domains point to my server. In cyradm, I 
created a mailbox for [EMAIL PROTECTED], where domain.com is the primary 
domain. I then added a password using saslpasswd2. Using imtest, I can 
authenticate [EMAIL PROTECTED] correctly. However, [EMAIL PROTECTED] fails: 
no user found.

Re: emails of multiple domain on one IMAP server

[Anthony Tibbs]

Hello George,
to fetch mail from a server you can use fetchmail and hand that mail to 
cyrus. I am not sure if you can hand it directly to cyrus or pass it first 
to an MTA like postfix which delivers email to cyrus.

Ulf
Assuming you have no "intermediary" processing via Postfix that you actually 
want to happen (for virus scans or what have you), Fetchmail can deliver 
directly to cyrus via lmtp.  That's how I have it setup here...

Cyrus 2.2.6 (Fedora Core 3) + Sendmail 8.13.1 + Virtual Domains

[Anthony Tibbs]

Hi everyone,
I'm a newbie to the mailing list, though I've been running Cyrus as 
something of my own personal IMAP server for the past 3 years, without a 
problem.  I'm just setting it up again on a new system, though, and decided 
to do it the 'right' way this time, and prepare for virtual domains right 
from the get-go.  (On my old setup, I ended up using table mappings, etc. to 
make this work without actually using Cyrus' virtdomains... it worked, but 
was a bit of a pain.)

Right now, everything is working, but I had to do some kludging to *get* it 
to deliver mail locally.  In particular, I've found the information about 
the "cyrusv2d" mailer for Sendmail, which is (supposed) to not strip the 
domain part of recipient addresses.  Alas, even delivering via cyrusv2d, 
Sendmail is still stripping the domain portion of local addresses (as 
evidenced by sendmail -bt tests).

The solution, for now?  Take the relevant domain out of 
/etc/mail/local-host-names, plunk it into /etc/mail/access as a 
To:mydomain.com RELAY entry.

I don't think this is how it is supposed to work, though, and I've got this 
nagging feeling that one of these days, this is going to prove to be a 
really problematic way of fixing it.  :)

Is there a "better" way that I've missed, given that 'cyrusv2d' doesn't seem 
to be doing the trick?

Take care,
Anthony Tibbs
