[Dovecot] Dovecot + Sieve
by Marcin M. Jessa 04 Sep '07

04 Sep '07

Hi guys. I installed dovecot 1.0.3 with sieve plugin. It looks like sieve is loaded fine by dovecot [1]. I set up dovecot to use sieve globally: protocol lda { mail_plugins = cmusieve quota sieve_global_dir = /usr/local/etc/sieve/Junk ..... } And created a sieve file which is supposed to move all the Spam marked by dspam to users's Junk folder (listed as Junk in the subscriptions file) : require ["fileinto"]; # Move spam to Junk folder if header :contains ["X-DSPAM-Result:"] "Spam" { fileinto "Junk"; # Stop here so that we do not reply on spams stop; } I also set up postfix to use pipe mail through dovecot: mailbox_command = /usr/local/libexec/dovecot/deliver The problem is dovecot seems to be ignoring my sieve rule and delivers emails directly to INBOX. Any idea how to fix that? [1]: deliver(user(a)domain.com): Sep 03 23:02:57 Info: Loading modules from directory: /usr/local/lib/dovecot/lda deliver(user(a)domain.com): Sep 03 23:02:57 Info: Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so deliver(user(a)domain.com): Sep 03 23:02:57 Info: Module loaded: /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so Cheers, Marcin. -- perl -e 'print $i=pack(c5,(41*2),sqrt(7056),(unpack(c,H)-2),oct(115), 10);' !DSPAM:351,46dc7a4820752062134273!

[Dovecot] Plugin development question
by Gary Smith 04 Sep '07

04 Sep '07

Hello, >From what I have read on the dovecot site, it's possible to create a plugin for a custom data store format. We have emails in a custom format in a database and would like to create a plugin for accessing these emails through dovecot. Is there any supporting documentation from creating a plugin like this? Are there any samples? TIA, Gary

[Dovecot] RHEL 5.1 beta, Dovecot 1.0.3: error while loading shared libraries?
by Patrick Ben Koetter 02 Sep '07

02 Sep '07

Hello, I try to run dovecot 1.0.3 on RHEL 5.1 beta. As soon as I start it I get the following output and it's impossible to IMAP-log in over network. I've been following the list for a while and it seems to ring a bell about setting the correct ulimit, but I can't find the thread anymore, so I need to ask. :( Here's the debug output I've put together. I've been not able to core dump dovecot as described in the debug docs: Sep 1 18:18:05 izlbw dovecot: imap-login: imap-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory Sep 1 18:18:05 izlbw dovecot: imap-login: imap-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory Sep 1 18:18:05 izlbw dovecot: pop3-login: pop3-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory Sep 1 18:18:05 izlbw last message repeated 2 times Sep 1 18:18:05 izlbw dovecot: child 28781 (login) returned error 127 Sep 1 18:18:05 izlbw dovecot: child 28782 (login) returned error 127 Sep 1 18:18:05 izlbw dovecot: child 28783 (login) returned error 127 Sep 1 18:18:05 izlbw dovecot: child 28784 (login) returned error 127 Sep 1 18:18:05 izlbw dovecot: child 28785 (login) returned error 127 Sep 1 18:18:05 izlbw dovecot: imap-login: imap-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory Sep 1 18:18:05 izlbw dovecot: child 28786 (login) returned error 127 Dovecot version: 1.0.3 built from atrpms.net src.rpm Operating system or Linux distribution name: # cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.1 Beta (Tikanga) CPU architecture (x86 or something else?): # uname -p x86_64 Filesystem you used: # mount /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) ...

[Dovecot] comparing pointer to integer?
by "Bérczi Gábor (Gabucino)" 01 Sep '07

01 Sep '07

For example in src/lib/file-cache.c: if (cache->mmap_base == MAP_FAILED) { Should be fixed, probably like this: if ((int)cache->mmap_base == MAP_FAILED) { There are a lot of occurences for these in the source. GCC only warns because of this, but DEC C is known to consider this an error: Error: file-cache.c, line 79: In this statement, "new_base" and "(-1)" may not be compared for equality or inequality. if (new_base == MAP_FAILED) { And indeed, unsigned integers and -1 are rarely equal. -- Gabucino

[Dovecot] Calculate Index size for harddisk sizing
by Patrick Ben Koetter 31 Aug '07

31 Aug '07

I need to get a hand on the 'usual size of an index' to do some hard disk sizing. Is that possible at all? I know their size depends a lot on what the clients index. Those clients will mostly be Outlook and Thunderbird and they will be doing more POP than IMAP if that helps to bring it down to some estimation.

Hello, I have old MBOX-trees from a dovecot-0.99-installation. I would like to integrate them into dovecot 1.0.0rc15 with Maildir. Sadly the old dovecot is no lonfger running, otherwise imapsync could be used. Does anybody can give some hints how to start? TIA Stephan

[Dovecot] rule of thumb for indexing overhead
by bill-dovecot＠carpenter.ORG 30 Aug '07

30 Aug '07

I realize it's hard to be precise about this, but does anyone have a feel or rule of thumb for a couple of aspects of indexing overhead? 1. Proportionally, how much space does it take for all 4 files? If I want to give my users a quota of 100 MB for messages, how much real space should I plan for so that I won't run out of space for indexing? 2. What's the overhead in rebuilding index files? Suppose I use an LDA other than dovecot, so at least the INBOX index is frequently getting out of date. Does it cost much (in CPU, memory, and disk IO) to rebuild the index files? (I'm using maildir.)

[Dovecot] quota imap_quota
by Bazy 29 Aug '07

29 Aug '07

Hello, I've been frying my brain with quota and mysql... Here is what I do: protocol imap { mail_plugins = quota imap_quota imap_client_workarounds = outlook-idle delay-newmail } plugin { # 10 MB + 1000 messages quota limit # quota = maildir:storage=10240:messages=1000 driver = mysql connect = host=/var/lib/mysql/mysql.sock user=mail_admin password=XXXXXXXX dbname=mail user_query = SELECT CONCAT(('/home/vmail/'), SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/'), CONCAT('5000'), CONCAT('5000'), CONCAT('maildir:storage=', quota) FROM users AS quota WHERE email = '%u'; } The querry output looks like this: +----------------------------------------------------------------------------------------------+----------------+----------------+-----------------------------------+ | CONCAT(('/home/vmail/'), SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/') | CONCAT('5000') | CONCAT('5000') | CONCAT('maildir:storage=', quota) | +----------------------------------------------------------------------------------------------+----------------+----------------+-----------------------------------+ | /home/vmail/goofy.celuloza.ro/bazy/ | 5000 | 5000 | maildir:storage=102400000 | +----------------------------------------------------------------------------------------------+----------------+----------------+-----------------------------------+ I made the query with http://wiki.dovecot.org/Quota?highlight=%28imap_quota%29 as an example. The result is: . OK Logged in. . capability * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS QUOTA . OK Capability completed. . getquotaroot Inbox . OK No quota. . getquotaroot inbox . OK No quota. . getquotaroot Trash . OK No quota. How can I get quota to work?... I'm out of ideas... and I'm an dovecot NUB... postfix sasl with dovecot with mysql with ENCRYPTED password works great, pop3 imap and imaps work great also. I just can't get quota to work... :( Any advice is welcome. Thank you!
