[Dovecot] Don't Know Where Emails Are Or What's Happening

Hi; I'm new to Dovecot and Postfix. I'm trying to enable these with MySQL support and postfixadmin. I've got all those services up and running (finally!); however, I can't figure out if the emails are being received and/or stored.

[Dovecot] Quota
by nuno marques 21 Oct '11

21 Oct '11

hi, I'm having some difficulty understanding the connection between postfix, dovecot and quota. What is the best way to set up quotas? through the file system quota and maildir? Need the dovecot lda working? The postfix needs a patch? I was thinking about setting quotas on file system, then configure Postfix to connect to dovecot-lda. Any suggestion? The system as a whole is composed of:dovecot-2.0-0.10.beta6.20100630.el6.x86_64 -> 2.0.beta6 (3156315704ef)openldap-servers-2.4.19-15.el6_0.2.x86_64postfix-2.6.6-2.1.el6_0.x86_64mailscanner-4.84.3-1.noarchspamassassin-3.3.1-2.el6.x86_64centos 6 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux

[Dovecot] Email filters
by Jos Chrispijn 21 Oct '11

21 Oct '11

Can someone tell me how I can configure Dovecot to use message filters on incoming email? When I now activate my mail account on my mobile phone and Thunderbird (or any other mail client with message filters) is not online, I get a huge pile of email in my INBOX that I have to go thru, while 90% is not that interesting to read as they belong to Spam messages, newsletters etc. Thanks in advance Jos Chrispijn

[Dovecot] Expire plugin not executing for sieve plugin?
by Dan Swartzendruber 20 Oct '11

20 Oct '11

Running dovecot 1.2.12 on ubuntu 10.10. Here is the problem: I have mysql backend for expire. I am using the dovecot-postfix package which creates /etc/dovecot/conf.d/01-mail-stack-delivery.conf which looks like this: # Some general options protocols = imap imaps managesieve disable_plaintext_auth = no ssl = yes ssl_cert_file = /etc/ssl/certs/ssl-mail.pem ssl_key_file = /etc/ssl/private/ssl-mail.key ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM mail_location = maildir:~/Maildir auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ # IMAP configuration protocol imap { mail_max_userip_connections = 10 imap_client_workarounds = outlook-idle delay-newmail mail_plugins = expire } # LDA configuration protocol lda { postmaster_address = postmaster mail_plugins = sieve expire quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r } # Plugins configuration plugin { sieve=~/.dovecot.sieve sieve_dir=~/sieve # If the user has no personal active script (i.e. if the file # indicated in sieve= does not exist), use this one: sieve_global_path = /var/lib/dovecot/sieve/default.sieve } The sieve is: require "fileinto"; require "imap4flags"; if header :contains "X-Spam-Flag" "YES" { setflag "\\Seen"; fileinto "SPAM"; stop; } Originally, this did not have the setflag or stop - I added them hoping to fix the problem, but no luck. The problem is this: when spam assassin has flagged a message as spam, the sieve runs and the message is in fact filed into the SPAM folder, but no expire entry is added to the database. If I move such a message from the SPAM folder to the Inbox and then back to SPAM, voila, I *do* get the entry created. Here is the mysql table before and after I did the move/move: mysql> select * from expires; +----------+---------------+--------------+ | username | mailbox | expire_stamp | +----------+---------------+--------------+ | dswartz | Deleted Items | 1319720163 | | dswartz | Sent | 1319120165 | | denise | Trash | 1319139920 | | samantha | Trash | 1319136146 | | denise | Sent | 1319655872 | | danielle | Sent | 1319192230 | | samantha | Sent | 1319268855 | | dswartz | Trash | 1319725884 | | samantha | SPAM | 1321504531 | +----------+---------------+--------------+ 9 rows in set (0.00 sec) mysql> select * from expires; +----------+---------------+--------------+ | username | mailbox | expire_stamp | +----------+---------------+--------------+ | dswartz | Deleted Items | 1319720163 | | dswartz | Sent | 1319120165 | | denise | Trash | 1319139920 | | samantha | Trash | 1319136146 | | denise | Sent | 1319655872 | | danielle | Sent | 1319192230 | | samantha | Sent | 1319268855 | | dswartz | Trash | 1319725884 | | samantha | SPAM | 1321504531 | | dswartz | SPAM | 1321714666 | +----------+---------------+--------------+ 10 rows in set (0.00 sec) It's almost like the fileinto stuff is not running the plugin code at all, or am I totally on drugs? If I can't get a fix for this, I at least now can think of a hack to "fix" it. e.g. every night, run a script that adds a "now" timestamp for everyone's SPAM folder to trick the periodic expire tool code into checking that folder, but obviously I'd rather have a real fix :) If this is just 'how it works', is it better in 2.0?

[Dovecot] too many open files and v1.2
by Michael Moritz 20 Oct '11

20 Oct '11

Hi I've found an older thread http://www.dovecot.org/list/dovecot/2010-March/047886.html which mentions that this is a bug in version 1. I'm on Debian squeeze (1:1.2.15-7) and got errors like these recently Oct 5 11:29:29 mail dovecot: dovecot: pipe() failed: Too many open files Oct 5 11:29:32 mail dovecot: dovecot: pipe() failed: Too many open files Oct 5 11:29:32 mail dovecot: dovecot: Temporary failure in creating login processes, slowing down for now As a work around I've increased login_max_processes_count from 256 to 512 and it seems to have helped (as I suspected stale opened files). My colleague thinks it's hitting the kernel open file limit ulimit -n (currently at 1024) but I don't see how that could happen if the number of process is nowhere near that. Any ideas? Thanks, Michael

[Dovecot] Is '*:bytes=" quota specification the quota 'Value', or 'Limit'?
by Rich 19 Oct '11

19 Oct '11

Docs for quota configuration http://wiki2.dovecot.org/Quota/Configuration#Limit_configuration state that the 'bytes=' specification defines the quota **LIMIT** "bytes: Quota limit in bytes, 0 means unlimited" as used in plugin { ... quota_rule = *:bytes=10000000 ... BUT, documentation for quota dict http://wiki2.dovecot.org/Quota/Dict states "MySQL uses the following queries to update the quota" and provides an SQL example of Dovecot decrementing the 'bytes' value, "UPDATE table SET bytes=bytes-14433,messages=messages-2 ..." I'm working on a current problem (http://dovecot.org/list/dovecot/2011-October/061538.html) with 'doveadm' reporting mixing up quote Value & Limit. Question: Is 'bytes' supposed to contain the Value, or the Limit? Rich
