[Dovecot] maildir++ quota bug...
by Joseph W. Breu 13 Jul '06

13 Jul '06

Running RC2 with maildrop and MDA: dovecot writes a positive quota count, then the negative quota count on messages delivered with maildrop. For example, message #1 arrives via maildrop: 4488236 1 message is deleted via dovecot: 4488236 1 -4488236 -1 This does not happen when the user accesses the message, only when it is deleted. The user never gets credit for deleting the file and their quota continues to grow. I did not notice this behaviour until now, but I just tested with rc1 and it is present there as well.

[Dovecot] proxy load-testing
by Vincent Fox 13 Jul '06

13 Jul '06

I found the proxy performance page in the Wiki. It's interesting to see such good performance for the proxy! However, I was trying to duplicate the tests and am not clear how. Anyone know what a typical test setup would look like? I need to document/test that I can setup a proxy able to handle 100-200 sessions per second which the folks around here are skeptical of. I emailed Tomi directly but got a vacation reply. I tried a quick test of my own with rabid and results seem questionable. Probably I am not using the right options on the command-line. I used a single client to generate the load and while I specified 20,000 per minute when I checked the maillog on my IMAP server it was authentication more like 300 per minute. I get a number of "Re-auth failure" messages even with 3720 accounts. I think this is due to the randomness being literal sometimes you hit again the same account name while a first attempt of it is still connected. Also not sure how Tomi generated those statistics, from the logs, from the rabid output? Since rabid doesn't do POP-mark numbers or anything I guess you just ramp up the load until the proxy slows down and call that your performance number?

[Dovecot] Squirrelmail Change Dovecot Password Plugin
by Cecil S. Nutakor 13 Jul '06

13 Jul '06

Hi Let me introduce myself, My name is Cecil, and i am a system architect by proferssion working currently on contracts with serveral companies in Ghana and Nigeria. I recently built a Corporate Mail Server for a Company using Postfix, Dovecot and Squirrelmail, running on Ubuntu. Thanks to the Dovecot community everything is working well. After a moment i noticed that i could make the users change their own passwords using squirrelmail, but unfortunatly for me after googling around the Internet and also visiting squirrelmail plugin page i could not find a change Dovecot password plugin for squirrelmail. I want to throw this challenge to the Dovecot community to start a project on developing a change Dovecot password plugin for squirrelmail if none exis t as at now. I am ready to voluntee towards the development of the plugin. I will like to know from others especially the list administrators if the project can take off on the mailling list with any problems. Thank You. Office Of The SYSTEMS ARCHITECT DISCOVERYTEL GH

Re: [Dovecot] Authentication by certificats (a bug or my misconfiguration)

Hi Alexander, > > Thanks for the quick reply; rearranging the certs didn't seem to do > much for the setup; I guess I'm getting one thing wrong, which was the > cause for my followup. How can I make dovecot only rely on cert and no > furhter authentication for giving access to the user, when making > dovecot lift the user ID from the client cert? Hmm, i don't think that's the reason for the "invalid certificate" error. Another question: are the clientcertificates and the servercertificate signed by the same CA? In case you want the ssl-verify error in the logfiles: in src/logincommon/ssl-proxy-openssl.c, line 607 change: i_info("Invalid certificate: %s", buf); to: i_info("Invalid certificate: %s: %s, X509_verify_cert_error_string(ctx->error) ,buf); should help, (tested on beta8) (don't forget to recompile, install, restart ;-)) success! -- groeten, HenkJan Wolthuis

Re: [Dovecot] Quota over 2GB supported?

Yes, we are enforcing a 5GB per user quota using Dovecot's maildir++ quota support. This works with both 32-bit kernels and 64-bit. I know courier took some patching to make work with 32-bit kernels, but Dovecot supports it out of the box. The only caveat is the quota is only enforceable within one namespace, so make sure your Inbox and folders all use the same namespace. Bill

[Dovecot] Corrupted index cache

Upgraded from rc1 to rc2 and I am still getting the Corrupted index cache file warnings in syslog Jul 12 10:10:19 pop1.cfu.net dovecot: IMAP(breu(a)cfu.net): Corrupted index cache file /var/spool/mail/filer/storage//cfu.net/b/r/breu/dovecot.index.cache: invalid record size Is this something to be worried about?

[Dovecot] passwd authentication issues (ATTN: Petar)
by Bruce Lane 12 Jul '06

12 Jul '06

Hi, Petar, For whatever reason, I didn't see your most recent reply until I checked the web archives. To answer your questions... Is my dovecot running chrooted? Not that I know of. However, the option to (apparently) decide this is confusing at best. Here is what I have entered. # chroot login process to the login_dir. Only reason not to do this is if you # wish to run the whole Dovecot without roots. # http://wiki.dovecot.org/Rootless login_chroot = yes Now, my guts tell me that this WILL make it run chrooted. However, reading the material at this link... http://wiki.dovecot.org/Rootless ...says otherwise, and that setting this to 'no' would be making it run chrooted. For reference, this is the process line from ps -aux|grep dovecot root 3182 0.0 1.4 256 876 ? Ss Sun08PM 10:10.06 /usr/local/sbin/dovecot Also, something else just turned up in the process list that I'm not sure I understand. Specifically... root 1817 0.0 1.6 324 1056 ? S 8:53PM 0:00.19 dovecot-auth dovecot 2191 0.0 3.0 256 1940 ? S 8:53PM 0:00.97 imap-login root 3182 0.0 1.4 256 876 ? Ss Sun08PM 10:11.78 /usr/local/sbin/dovecot dovecot 6333 0.0 3.0 256 1940 ? S 8:53PM 0:00.93 imap-login dovecot 8133 0.0 3.0 256 1940 ? S 8:53PM 0:00.97 imap-login dovecot 8397 0.0 3.0 256 1940 ? S 8:53PM 0:00.96 imap-login dovecot 16144 0.0 3.0 256 1940 ? S 8:53PM 0:00.92 imap-login This has me deeply confused. I'm not running IMAP, I'm not interested in running IMAP, I don't want anything to do with IMAP. However, there's five processes for imap-login. What gives? On to your second question: Are /etc/pwd.db and /etc/spwd.db available? Yes, both are listed in the directory of /etc as follows. -rw-r--r-- 1 root wheel 40960 Jul 9 09:56 /etc/pwd.db -rw------- 1 root wheel 40960 Jul 9 09:56 /etc/spwd.db featherweb: {41} How "available" this makes them (I don't know what context you were asking in), I'm not sure. Just for giggles, I tried chaning the permissions on spwd.db so that it was world-readable. Doing so had no effect. I still get password failure errors when I try to authenticate a pop3s connection from the client program. One other question: Pegasus (the mail client) has two options for secure POP connections besides apop (which I've shelved for the moment): STLS and direct SSL connection. I've got it set to direct SSL at the moment. Does this sound right? Looking forward to the next set of replies.

[Dovecot] Problems with deliver (LDA)
by Claus Alboege 12 Jul '06

12 Jul '06

Hi, I'm using Dovecot's (1.0.rc2) 'deliver' (no sieve) as LDA - calling it from a .qmail file. It seems that 'deliver' destroys "message/rfc822" attachments (forward as attachment). My .qmail file looks like this, and use qmail to deliver a copy directly to my Maildir, and 'deliver' to deliver a second copy of the same message to the same Maildir: % cat .qmail ./Maildir/ |preline /usr/libexec/dovecot/deliver After forwarding a message (as attachment) to my account, I get the following 2 files in my Maildir. Check the difference in size: % ls -l Maildir/new -rw------- 1 csa csa 2818 2006-07-06 09:29 1152170973.7420.silver -rw------- 1 csa csa 1372 2006-07-06 09:29 1152170973.P7422Q0M136220.silver Grepping for ^Content-* in the 2 mails show that a part is missing. % cd Maildir/new % grep ^Content * 1152170973.7420.silver:23:Content-Type: multipart/mixed; 1152170973.7420.silver:28:Content-Type: text/plain; charset = "iso-8859-1" 1152170973.7420.silver:29:Content-Transfer-Encoding: quoted-printable 1152170973.7420.silver:34:Content-Type: message/rfc822; name="Testing" 1152170973.7420.silver:35:Content-Transfer-Encoding: 7bit 1152170973.7420.silver:36:Content-Disposition: attachment; filename="Testing" 1152170973.7420.silver:64:Content-Transfer-Encoding: quoted-printable 1152170973.7420.silver:65:Content-Type: text/plain; charset="iso-8859-1" 1152170973.P7422Q0M136220.silver:24:Content-Type: multipart/mixed; 1152170973.P7422Q0M136220.silver:29:Content-Type: text/plain; charset = "iso-8859-1" 1152170973.P7422Q0M136220.silver:30:Content-Transfer-Encoding: quoted-printable 1152170973.P7422Q0M136220.silver:35:Content-Type: message/rfc822; name="Testing" 1152170973.P7422Q0M136220.silver:36:Content-Transfer-Encoding: 7bit 1152170973.P7422Q0M136220.silver:37:Content-Disposition: attachment; filename="Testing" (sorry for the long lines) The offset in linenumbers is caused the the From line added by 'deliver'. So, am I missing something here (execpt from the attachment) - is there anything in 'deliver' that could cause this behaviour? Please let me know if you need further information or details.
