[Dovecot] Problem with openldap+nscd+dovecot
by Oliver Schulze L. 29 Nov '05

29 Nov '05

Hi, I'm having a problem with this setup: RHEL4 U4.2(Centos) + openldap + nscd The problem I see is that for some reason, after a couple of hours dovecot stuck in the auth procress. I do a : telnet localhost imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 login user pass (here is the delay) After passing a username/password, the process is like stuck for some reason. I have to killall dovecot processes and do a: service dovecot restart and it work again. I have 1.5GB left on the disk and this problem just appeared now after month of working correctly. Could it be the disk space? How can I debug the problem? Should I migrate de 1.0alpha4? Does alpha4 have a new code in the authentication phase? Regards, Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

[Dovecot] Not an IMAP4 Server?
by John Gray 28 Nov '05

28 Nov '05

I've been testing alpha4, and every once in a while my client (Thunderbird 1.5 RC1) tells me the dovecot isn't a valid IMAP4 server. This is usually (maybe always) when I first bring up the client up. If I just ask the client to get the mail again, it does so happily (without any errors). I must say I found dovecot as a pleasant surprise. We have been using UW. Which didn't scale well. I was considering going to cyrus, but dovecot seems to have given much (if not all) of performance improvements without all the hassle of conventing all the existing mbox mail to maildir.

[Dovecot] Re: Pop-before-smtp and MySQL?
by Matteo Garofano 28 Nov '05

Thanks for your reply, I know that smtp auth is far better from pop-before-smtp but I have to replace a qpopper daemon and not ask any change from client site (they are thousands ...) So I must do the kind of setting I described. If you have any suggestion... thanks again Bye te0x ----- Original Message ----- From: "Matteo Garofano" <m.garofano(a)internetware.it> To: <dovecot(a)dovecot.org> Sent: Monday, November 28, 2005 12:40 PM Subject: Pop-before-smtp and MySQL? > Hi, > I found that dovecot have many nice features. > Now I write because I'm tring to setup the dovecot server, I would > substitute a qpopper daemon (patched for mysql authentication) > The problem I find is to set up the pop-before-smtp using sql (mysq) as > written in http://wiki.dovecot.org/moin.cgi/PopBSMTPAndDovecot > (Waiting for post_login ;-) > I would use the script popbsmtp.sh and not a perl pig.

[Dovecot] authentication failure messages in log
by Daniel 26 Nov '05

26 Nov '05

Hi I'm using Dovecot 1.0.stable branch on a production Fedora Core 3 server. All is running very well other than I getting tons of these messages in the log (/var/log/messages): Nov 26 13:38:56 bmw unix_chkpwd[19360]: password check failed for user (xxxx) Nov 26 13:38:56 bmw imap(pam_unix)[19359]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=x.x.x.x user=xxxx However the sessions are authenticating correctly and the user is able to down load the mail fine. I have tested this. I send mail to an account then login and download the mail correctly, however my session gets the above in the messages log. Each log on to dovecot get ones of these messages in the log. It making the log file large. Any idea on what it is? Regards Daniel -- "Unix is simple.

[Dovecot] Problem with mysql authentication
by Jacek Osiecki 25 Nov '05

25 Nov '05

Hi, I'm trying to set up dovecot-stable (http://www.dovecot.org/nightly/stable/dovecot-stable-20051124.tar.gz) All seems to be prepared correctly, but... my dovecot can not access the mysql database :( Connection string goes like this (i tried changing the order of parameters, that's why password is the first in the line): connect = password=***** host=/var/lib/mysql/system/mysql.sock dbname=vmail user=vmail But - in dovecot log I see: dovecot: Nov 24 23:53:05 Error: auth(default): mysql: Connect failed to vmail: Access denied for user 'vmail'@'localhost' (using password: TAK) Same in mysql log: 051124 23:53:05 171 Connect Access denied for user 'vmail'@'localhost' (using password: TAK) All settings in connection string are 100% correct - I have pasted them from dovecot-sql.conf to command-line mysql client and it worked, I have logged in. My copy of dovecot has been compiled recently, so all libraries are correct. Mysql version is 5.0.15 - but I doubt it is the reason... Can anyone help? Thanks in advance!

[Dovecot] Newbie question: shared folders means..?
by Jeff Turner 22 Nov '05

22 Nov '05

Hi, The website says "Shared mailboxes aren't yet supported". Does that mean that one shouldn't have two mail clients (same username) accessing the same IMAP account simultaneously? Or that Dovecot doesn't support distinct users accessing the same 'shared' Maildir box? Cheers, Jeff

[Dovecot] Silly question...
by Michael Segel 22 Nov '05

22 Nov '05

I'm trying to build a new 1.0+ copy of dovecot. I'm trying to build it so I can use SSL. I tried the ./configure --with_ssl= option, did a make clean, then a make and a make install. Still get the same error saying that even though I set the SSL use flag, it was not compiled with SSL. Thoughts? TIA! -- Michael Segel Principal MSCC 312 952- 8175 [M]

[Dovecot] Assertion Failure
by Todd Burroughs 22 Nov '05

22 Nov '05

Here's an assertion failure that just happened. Unfortunately, I don't have a core file so this may be useless... This is with CVS version from 2005-11-03. It looks like he expunges all of his mail. dovecot: Nov 21 17:37:20 Error: 13261 imap(username): mbox sync: Expunged message reappeared in mailbox /mailhome/new/b/n/username/mbox (UID 1008 < 1606, seq=816, idx_msgs=1238) dovecot: Nov 21 17:37:23 Error: 13261 imap(username): file mail-index-transaction.c: line 129 (mail_index_buffer_convert_to_uids): assertion failed: (*seq != 0) dovecot: Nov 21 17:37:24 Error: child 13261 (imap) killed with signal 6

[Dovecot] What's the best way to do this?
by Michael Segel 22 Nov '05

22 Nov '05

Hi, Got a situation where I have a couple of mailing list subscriptions as well as system generated e-mails from my clients' computers sending me warning messages. (Along with my normal load of personal e-mail). Does it make sense to set up virtual mailboxes (maildirs) one for each mailing list or group? Then using an IMAP client to subscribed only to the lists that I *want* to read? My biggest problem is that I have a blackberry and I don't want to get interrupted for non-critical e-mail. Or is there a better solution? TIA! -Mikey -- Michael Segel Principal MSCC 312 952- 8175 [M]
