[Dovecot] Sieve and UserDB/SQL support
by ben＠benweblife.fr 13 Oct '11

13 Oct '11

Hi, I would like to know if plugins of sieve support UserDB/SQL backend. For example, for the vacation plugin, is it possible to retrieve a field like "sieve_vacation_days", "sieve_vacation_reason", and so on.. on user_query? Or, there is a plan for implement this? Thanks ------ dovecot version: 2.0.13

[Dovecot] Dovecot not processing through Sieve
by Steven Kiehl 13 Oct '11

13 Oct '11

Hello everyone, I'm fairly new to Dovecot, but I've gotten the majority of things working except for Sieve. I'm running Dovecot 1.2.9 coupled with Postfix and SpamAssassin all with a virtual domains setup. I am receiving mail and it is being processed by all the plugins that operate through Postfix. The quota configured in Dovecot appears to be working because my mail client shows the configured quota. But the Sieve rules are not processing. I created a rule as follows to filter spam: require ["fileinto"]; # rule:[global-spam] if anyof (header :contains "Subject" "[SPAM]", header :contains "X-Spam-Flag" "YES") { fileinto "Junk"; } If I mail myself a message with [SPAM] in the title, it goes into my inbox regardless. I've run 'sieve-test' with the same email and it says it will file it into Junk. The Junk folder exists. I even tried adding :create and the "mailbox" plugin, but that didn't do anything either. Here is the relevant majority of my dovecot configuration: login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:/home/dovecot/mail/domains/%d/%n/Maildir mail_debug: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve imap_client_workarounds(default): outlook-idle delay-newmail tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle delay-newmail tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: *mail_plugins: quota sieve* quota_full_tempfail: yes deliver_log_format: msgid=%m: %$ rejection_reason: Your message to <%t> was automatically rejected:%n%r auth default: mechanisms: cram-md5 plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: dovemail group: dovemail socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix plugin: convert_mail: maildir:/home/dovecot/mail/domains/%d/%u/Maildir * sieve: /etc/dovecot/sieve/domains/%d/%n.sieve* * sieve_global_dir: /etc/dovecot/sieve/global/* quota: maildir:User quota_rule: INBOX:storage=500M quota_rule2: INBOX.Trash:storage=100M The sieve plugin exists in /usr/lib/dovecot/modules/lda/lib90_sieve_plugin.so, so I would assume I'd have to use *mail_plugin: sieve* as my configuration setting. Like I said, I am receiving emails to my domains without any problem, but sieve rules are not being processed. I can see the rules set up by using the Roundcube plugin, and I can create and edit rules through Roundcube, but nothing different happens when I send myself an email. It all just delivers to the inbox. Thanks for your help, Steve K.

[Dovecot] Auth Worker failures
by Simon Brereton 12 Oct '11

12 Oct '11

Hi I have a script that checks the logs each day and mails me invalid user attempts and authentication failures for the previous day. (I use fail2ban to ban multiple attempts in a short space of time). For some reason, this appears every day: Oct 11 06:25:12 mail dovecot: auth-worker(default): sql(simon(a)mydomain.net,127.0.0.1): Password mismatch Oct 11 06:25:19 mail dovecot: auth-worker(default): sql(simon(a)mydomain.net,127.0.0.1): Password mismatch Oct 11 06:25:31 mail dovecot: auth-worker(default): sql(simon(a)mydomain.net,127.0.0.1): Password mismatch Oct 11 06:25:48 mail dovecot: auth-worker(default): sql(simon(a)mydomain.net,127.0.0.1): Password mismatch Oct 11 06:26:10 mail dovecot: imap-login: Aborted login (auth failed, 4 attempts): user=<simon(a)mydomain.net>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Of all the accounts on the box, it's only mine that throws this up. Since its LIP is localhost, it could really only be for webmail - but I don't always leave the webmail open, so I'm curious to know how this gets there and what it is. Any suggestions? I find it difficult to believe I have an IMAP process in a script somewhere (especially with my user account - the postmaster account, I could believe, but not with my personal one).. The log time is UTC, so watching the process list at 2.24 is less than appealing! Simon

[Dovecot] To query two SQL tables for user verification over LMTP, should I use (a) two separate lookups? or (b) just one lookup with a boolean query?
by jake0534＠airpost.net 12 Oct '11

12 Oct '11

Hey all I've been running a Dovecot 1X server for awhile. Most of the config was pretty simple using flat files. I'm switching to Dovecot 2X now, and want to switch to using SQL for lookups so I can share info with the Postfix front end. For starters I setup two SIMPLE SQL tables -- a 'users' table and a 'aliases' table, where each user can have many aliases. I want to have Postfix check Dovecot's SASL/LMTP passdb to see if a <user>@<domain> exists. If yes, deliver through LMTP. If NO, reject it. Here are the table definitions so far, CREATE TABLE user ( userid TINYINT, user VARCHAR(64), domain VARCHAR(128), password VARCHAR(64), PRIMARY KEY (userid), UNIQUE (user,domain) ); CREATE TABLE alias ( aliasid TINYINT, alias VARCHAR(64), user VARCHAR(64), domain VARCHAR(128), PRIMARY KEY (aliasid), UNIQUE (domain,user,alias), CONSTRAINT fk_alias1 FOREIGN KEY (user) REFERENCES user (user) ON DELETE NO ACTION ON UPDATE NO ACTION, CONSTRAINT fk_alias2 FOREIGN KEY (domain) REFERENCES user (domain) ON DELETE NO ACTION ON UPDATE NO ACTION ); With flat file and just one table, 'users', I get how to setup LMTP. I can get Postfix delivering/rejecting over LMTP depending on if the user exists in the Dovecot passdb or not. I don't get how to do the SQL query in Dovecot if I have the TWO tables. An inbound <user>@<domain> needs to be auth'd as valid if it exists in EITHER 'user' OR 'alias' table. Do I need to use a single lookup for passdb with some sort of "IF EXISTS IN TABLE 'user' OR TABLE 'alias'" query? Or do I need to have TWO lookups, the main one for 'user' and a fallback one for 'alias' (like talked about here http://wiki2.dovecot.org/Authentication/MultipleDatabases)? Cheers! Jake

[Dovecot] using ecc-certificates (ellyptic curve) will not establish connection

hi I want to use ECC(ellyptic curve cryptography) for SSL-connections but somehow dovecot doesn't like my ECC-certificates :( I tried to test using following scenario: machine: debian 6 (x64) dovecot 2.0.15-0~auto+21 ((f6a2c0e8bc03) from http://xi.rename-it.nl/debian openssl 1.0.0e-2 from testing (as the default 0.9.8o-4squeeze3 needs also the parameter -cipher ECCdraft for testing) creating keys+cert for ecc (i.e. curves prime192v1, secp521r1) # openssl ecparam -name prime192v1 -genkey -out prime192v1.key # openssl req -new -key prime192v1.key -out prime192v1.csr # openssl req -x509 -in prime192v1.csr -key prime192v1.key -out prime192v1.crt testing these in 2 windows # openssl s_server -cert prime192v1.crt -key prime192v1.key -www # openssl s_client note: when using the default openssl version 0.9.8o-4squeeze3 you need to append -cipher ECCdraft output (cut) ...

[Dovecot] inbox issue
by Eric Broch 10 Oct '11

10 Oct '11

I have dovecot 2.0.11 installed on a CentOS 5.7 email server. Two of the server email clients, one using Outlook and the other Thunderbird, have had all the contents of their inbox disappear only to reappear at a later time. One client's inbox email reappeared upon receiving a test email (to check if it would show up in the inbox) from another user. Has anyone heard of such a thing? Here's a dump of my dovecot configuration. # 2.0.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-238.19.1.el5 i686 CentOS release 5.7 (Final) auth_anonymous_username = anonymous

Re: [Dovecot] Filesystem quotas

Timo Sirainen writes in response to Steve Fatula's query: > With imap_quota plugin it allows IMAP client to see how much quota is > used/left. You could also enable quota warnings. And configure the > quota exceeded error message. It could also prevent the catch-22 situation I wrote about earlier whereby a filesystem out-of-space condition will result in a user not being able get themselves out of that situation, since a mailbox operation (like a delete and expunge) will not be able to create a lockfile. Having quotas handled by the IMAP/LDA will allow extra room to handle this impasse. Disabling dotlock or using dotlock_try locking method are some other workarounds.

[Dovecot] Timeout leak in get quota
by Danilo 10 Oct '11

Hello! I wrote perl script for read current quota usage, it works but when I run the program I receive a warning in Dovecot log: 2011-09-29 14:45:30 doveadm(guest(a)testmail.com): Warning: Timeout leak: 0x7f14800ad970 This is the script: =============================== #!/usr/bin/perl use strict; use Socket; use IO::Handle; socket(TSOCK, PF_UNIX, SOCK_STREAM,0); connect(TSOCK, sockaddr_un("/var/run/dovecot/doveadm-server")) or print("ERROR!"); print "VERSION\tdoveadm-server\t1\t0\n"; print "\tguest\(a)testmail.com\tquota get\n"; print "=" x 20 . "\n"; if (defined(my $messg = <TSOCK>)) { print $messg; print TSOCK "VERSION\tdoveadm-server\t1\t0\n"; TSOCK->flush; print TSOCK "\tguest\(a)testmail.com\tquota get\n"; TSOCK->flush; $messg = <TSOCK>; print $messg; $messg = <TSOCK>; print $messg; close TSOCK; } ============================= I hope someone could help me to fix the warning. Thanks in advance, Dany
