[Dovecot] MacOS X and quota-plugin
by Lars Skovgaard 13 Nov '06

13 Nov '06

Hi all, I've installed dovecot 1.0 rc12 on a MacOS X client system with only a handful of users – all virtual – and would like to enable quotas. I've tried searching the wiki for information on how to do this, but haven't been able to find anything – which is why I turn to the list in hope there's someone out there who can point me in the right direction. I've compiled dovecot without any other authentication than sql and pam, and have enabled ssl, pop3 and dovecot lda (for use with postfix when I get around to it). The installation went smoothly, and dovecot is working great without quota-support. However, when I enable quota- support, the imap child-process crashes. Here's a few lines from the log, slightly altered to protect user-identities: Nov 8 23:05:09 SD-Server dovecot: imap-login: Login: user=<imapuser>, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:09 SD-Server dovecot: child 22662 (imap) killed with signal 11 Nov 8 23:05:09 SD-Server crashdump[22663]: imap crashed Nov 8 23:05:09 SD-Server crashdump[22663]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:12 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:13 SD-Server dovecot: child 22665 (imap) killed with signal 11 Nov 8 23:05:13 SD-Server crashdump[22666]: imap crashed Nov 8 23:05:13 SD-Server crashdump[22666]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:16 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:17 SD-Server dovecot: child 22670 (imap) killed with signal 11 Nov 8 23:05:17 SD-Server crashdump[22671]: imap crashed Nov 8 23:05:17 SD-Server crashdump[22671]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log This is what I have done in dovecot.conf to enable quota: protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap } plugin { #quota = dict:storage=10240 #quota = dirsize:storage=10240 #quota = maildir:storage=10240 #quota = maildir:storage=10240 mysql:/usr/local/etc/dovecot-sql.conf #quota = fs:storage=10240 #quota = fs } As you might guess from the lines under "plugin", I've tried a lot of different combinations. If I enable ANY of the above lines under plugin, the child-processes die upon login. When all have been commented out, there's no more crashing – until I try to see how much space is available, then it crashes again. I've tried adding an extra "quota" field to my mysql userdb to handle quotas, but with the same result. mysql-query looks like this (as described in the wiki): user_query = SELECT home, uid, gid, 'dirsize:storage=' || quota_kb AS quota FROM users WHERE userid = '%u' As with the settings in dovecot.conf, Ive tried various combinations of dict, dirsize and so on, but without any luck. This is what the entries in my crashdump file looks like: Host Name: SD-Server Date/Time: 2006-11-09 00:06:17.151 +0100 OS Version: 10.4.7 (Build 8J135) Report Version: 4 Command: imap Path: /usr/local/libexec/dovecot/imap Parent: dovecot [8370] Version: ???

[Dovecot] my_strncasecmp ignores max_chars
by Ben Winslow 13 Nov '06

my_strncasecmp ignores the length parameter, which breaks all sorts of things on platforms where the function actually gets used. Trivial patch attached. -- Ben Winslow <rain(a)bluecherry.net>

Procmail writes to the folders, but it uses dotlocks, and I don't have logs of it crashing, whereas I do have logs of dovecot crashing :) I'm confused as to what the last sentence says, do you mean that you were able to reproduce the crash?

Hello dovecot, It seems, that mail_chroot setting can't use variables. I try to set it to `%h' and it deosn't work :( Are here any security considerations, or it is bug? -- Best regards, Lev mailto:lev@serebryakov.spb.ru

[Dovecot] 1.0.rc11 released
by Timo Sirainen 12 Nov '06

12 Nov '06

http://dovecot.org/releases/dovecot-1.0.rc11.tar.gz http://dovecot.org/releases/dovecot-1.0.rc11.tar.gz.sig Hopefully the last RC release? As far as I know there are no major problems left now. If nothing big shows up, v1.0 should be out in a couple of weeks. * Renamed default_mail_env to mail_location. default_mail_env still works for backwards compatibility. * deliver: When sending rejects, don't include Content-Type in the rejected mail's headers. * LDAP changes: * If auth binds are used, bind back to the default dn before doing a search. Otherwise it could fail if a user gave an invalid password. * Initial binding at connect is now done asynchronously. * Use pass_attrs even with auth_bind=yes since it may contain useful non-password fields. + passdb checkpassword: Give TCPLOCALIP and TCPREMOTEIP and PROTO=TCP environments to the checkpassword binary so we're UCSPI (and vchkpw) compatible. - mbox handling was a bit broken in rc10 - Using Dovecot via inetd kept crashing dovecot master - deliver: Don't crash with -f "". Changed the default from envelope to be "MAILER-DAEMON". - INBOX wasn't shown with LSUB command if only prefixed namespaces were used. - passdb ldap: Reconnecting to LDAP server wasn't working with auth binds. - passdb sql: Non-plaintext authentication didn't work - MySQL passdb ignored all non-password checks, such as allow_nets - trash plugin was broken

[Dovecot] Deliver: command time exceed limit
by Dominique Feyer 12 Nov '06

12 Nov '06

We use Dovecot on a cluster (10'000 domains, 30'000 account) without any problem with pop/imap. We use Dovecot 1.0 RC10 Now we use virtual transport from postfix for mail delivery. We need the Dovecot LDA for sieve support. We test this solution on some domains with success. But if we change the configuration of all our domains, we have a lots of bounce with this error in postfix log: postfix/pipe[24573]: 4F6D7CF11: to=<info(a)XXXX.com>, relay=dovecot, delay=1200, status=bounced (Command time limit exceeded: "/usr/local/dovecot/libexec/dovecot/deliver") If I watch the deliver activity with ps/awk/watch, I see that if deliver duration time exceed some seconds, the deliver process stay in memory but do nothing. Here a strace output of this case: Process 349 attached - interrupt to quit gettimeofday({1161965973, 768478}, {0, 0}) = 0 poll( Strace output nothing before the SIGKILL from postfix (command time exceed 1200 second), the end of the strace: [{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=9, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 2147483647) = -1 EINTR (Interrupted system call) +++ killed by SIGKILL +++ I'm not sure is this problem has a relation with our deliver problem. But in the deliver log /var/log/dovecot/deliver, I have a lots of message: deliver(info(a)labomex.com): 2006.10.27 18:29:28 Error: file_dotlock_replace(/var/mail/labomex.com/mails/info/.dovecot.lda-dupes) failed: No such file or directory deliver(info(a)labomex.com): 2006.10.27 18:29:28 Error: rename(/var/mail/labomex.com/mails/info/.dovecot.lda-dupes.lock, /var/mail/labomex.com/mails/info/.dovecot.lda-dupes) failed: No such file or directory Our dovecot.conf (lda parts): protocol lda { postmaster_address = postmaster(a)clm.net4all.ch #hostname = mail_plugins = cmusieve mail_plugin_dir = /usr/local/dovecot/lib/dovecot/lda sendmail_path = /usr/sbin/sendmail auth_socket_path = /var/run/dovecot/auth-master log_timestamp = %Y.%m.%d %H:%M:%S%t log_path = /var/log/dovecot/deliver info_log_path = /var/log/dovecot/deliver.info } We use on UID/GID per domain so every account of a domain use the same UID/GID. The mail storage is on a Debian Sarge NFS server with 2.4.27-3-686-smp. Indexes are stored localy on each POP/IMAP/LDA server. I don't understand why we have this problem. If somebody can help us, thanks a lots. Dominique Feyer

[Dovecot] Writing to mail directory

FreeBSD 6.1 Dovecot 1.0.rc12 Using Dovecot as an LDA produces this error message: // START ERROR MESSAGE // deliver(gerard): Error:open(/var/mail/.temp.scorpio.seibercom.net.812.03034e3c3c1ab1c8) failed: Permission denied deliver(gerard): Error: file_lock_dotlock() failed with mbox file /var/mail/gerard: Permission denied // END ERROR MESSAGE// Actually, there are dozens of similar messages for all of my accounts. One example is enough to see what I am referring to. I am using Postfix for my mail-server. If I change the permissions on the directory to '1777' the error goes away and everything seems normal. The problem is that I should not have to do that and I do not understand what the problem is. Has anyone else experienced this phenomena and come up with a solution? Thanks! -- Gerard "Off list mail from *.gmail.com is rejected/deleted unseen. Don't waste your time."
