Sieve: carry global variables from sieve_before to user sieve scripts
by Alexander 'Leo' Bergolth 26 Oct '14

26 Oct '14

Hi! Is there a way to initialize global variables with default values in sieve_before scripts that can be used in the sieve_default script or in user scripts? I've tried the following code but this doesn't work.. before.d/10-set-defaults.sieve: -------------------- 8< -------------------- require ["variables", "include"]; require "vnd.dovecot.debug"; set "global.S_TESTVAR leo"; debug_log "LEO SIEVE: in before.d/10-set-defaults, S_TESTVAR: ${global.S_TESTVAR}"; -------------------- 8< -------------------- default.sieve: -------------------- 8< -------------------- require ["variables", "include"]; require "vnd.dovecot.debug"; global "S_TESTVAR"; debug_log "LEO SIEVE: in default.sieve: S_TESTVAR: ${global.S_TESTVAR}, ${S_TESTVAR}"; -------------------- 8< -------------------- Is there any other way to set up defaults in a global sieve script?

imap-postlogin and doveadm
by Hans Morten Kind 25 Oct '14

25 Oct '14

We are configuring location= running a bash-script during imap-postlogin setting $MAIL in $USERDB_KEYS, as described in wiki/PostLoginScripting.txt This works fine. However, running a command like 'dovadm index [-u user] folder' only works for users with settings that match the default in mail_location= Would it be possible to make the location available for doveadm in a similar way, either with command line arguments or in the enviroment? hmk

Dynamic tags in email address
by Felix Gustavsson 25 Oct '14

25 Oct '14

I'm trying to get dynamic tagging (user+sometag(a)example.com) to work on a mail server I'm setting up, however it only works as long as it's sent to the main user and not to aliases. virtual-alias-maps query: SELECT get_email_alias_dyn('%s') virtual-mailbox-domains query: SELECT 1 FROM domain WHERE name='%s' virtual-mailbox-maps query: SELECT 1 FROM user_alias INNER JOIN domain ON user_alias.domainID = domain.id WHERE user_alias.primary = 1 AND CONCAT(user_alias.name, '@', domain.name)='%s' "get_email_alias_dyn()" is a stored function which returns the destination email, so alias+tag(a)example.com returns user(a)example.com, alias(a)example.com returns user(a)example.com and so on. It works perfectly fine when the mail does not contain any tags (alias(a)example.com or user(a)example.com) or if it's the primary email which contains tags (user+sometag(a)example.com) but when it's tags on an alias the mail is bounced due to "user unknown". I tried modifying the dovecot service in master.cf so the addresses can be filtered with Sieve (http://wiki2.dovecot.org/LDA/Postfix) but that did not solve the issue either, so I have not idea where it goes wrong or how to solve it. I have included the logs from when I sent to alias+tag(a)example.com below: Oct 25 19:54:20 xx postfix/smtpd[10987]: connect from mail-wg0-f50.google.com[74.125.82.50] Oct 25 19:54:21 xx postfix/smtpd[10987]: 10585DFA63: client=mail-wg0-f50.google.com[74.125.82.50] Oct 25 19:54:21 xx postfix/cleanup[10995]: 10585DFA63: message-id=<CAGPeO-YcJwbRJb-Gfga+G_vKqj9cm80rMZf9LAfENRCFfxLVAg(a)mail.gmail.com> Oct 25 19:54:25 xx postfix/qmgr[9945]: 10585DFA63: from=<xx(a)gmail.com>, size=1743, nrcpt=1 (queue active) Oct 25 19:54:25 xx postfix/smtpd[10987]: disconnect from mail-wg0-f50.google.com[74.125.82.50] Oct 25 19:54:25 xx dovecot: auth-worker(11000): mysql(127.0.0.1): Connected to database mailcp Oct 25 19:54:25 xx postfix/pipe[10998]: 10585DFA63: to=<xx+test(a)xx.com>, relay=dovecot, delay=5.4, delays=5.4/0/0/0.03, dsn=5.1.1, status=bounced (user unknown) Oct 25 19:54:25 xx postfix/cleanup[10995]: D39B2DFC7D: message-id=<20141025175425.D39B2DFC7D(a)xx.com> Oct 25 19:54:25 xx postfix/bounce[11002]: 10585DFA63: sender non-delivery notification: D39B2DFC7D Oct 25 19:54:25 xx postfix/qmgr[9945]: D39B2DFC7D: from=<>, size=3937, nrcpt=1 (queue active) Oct 25 19:54:25 xx postfix/qmgr[9945]: 10585DFA63: removed Oct 25 19:54:26 xx postfix/smtp[11004]: D39B2DFC7D: to=<xx(a)gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.195.27]:25, delay=0.24, delays=0/0/0.16/0.07, dsn=2.0.0, status=sent (250 2.0.0 OK 1414259666 d8si5463492wiv.41 - gsmtp) Oct 25 19:54:26 xx postfix/qmgr[9945]: D39B2DFC7D: removed The dovecot-sql.conf.ext file looks like this: driver = mysql connect = host=127.0.0.1 dbname=mailcp user=mailcp password=xxx default_pass_scheme = SHA512-CRYPT password_query = SELECT CONCAT(user_alias.name, '@', domain.name) as user, user.password as password, concat('*:bytes=', (CASE WHEN user.quota -1 THEN user.quota ELSE domain.quota END)*1000000) AS userdb_quota_rule FROM user INNER JOIN user_alias ON user.id = user_alias.userID AND user_alias.primary = 1 INNER JOIN domain ON user_alias.domainID = domain.id WHERE CONCAT(user_alias.name, '@', domain.name) ='%u' AND user.status = 1 user_query = SELECT CONCAT('/var/mail/vmail/', domain.name, '/', user_alias.name) as home, 5000 AS uid, 5000 AS gid, concat('*:bytes=', (CASE WHEN user.quota != -1 THEN user.quota ELSE domain.quota END)*1000000) AS userdb_quota_rule FROM user INNER JOIN user_alias ON user.id = user_alias.userID AND user_alias.primary = 1 INNER JOIN domain ON user_alias.domainID = domain.id WHERE CONCAT(user_alias.name, '@', domain.name) ='%u' AND user.status = 1

Sieve duplicate detection
by Bruce Bodger 25 Oct '14

25 Oct '14

Good day, Gents. We are running: dovecot 1.2.17 dovecot-1.2-sieve-0.1.19 dovecot-1.2-managesieve-0.11.13 postfix 2.4.3 on OS X 10.5.8 server. Only about 15 users access the server. No problems. My question is... what would I have to upgrade, and to what version, in order to take advantage of pigeonhole sieve's duplicate detection (vnd.dovecot.duplicate) functionality? Thank you very much.

Invoking the spam checker on the sieve script
by Alejandro Exojo 25 Oct '14

25 Oct '14

Hi. TL/DR version: Is it advisable to invoke an spam checker from the sieve script, and then, once the message is filtered, decide if should be moved to a certain spam folder? A bit more context on why I'm considering this: I'm just a geek who wants to handle his own mail, but not a great experience as a system administrator. I don't have any corporate setup, just a simple VPS with me as the only user. Previously I fetched all my mail through POP, and in the client of my PC I moved (lots of) mailing list traffic to its folders. Then, for those remaining messages (and only those remaining) I passed the spam filter and moved to spam folder. That's a significant saving since I have many mailing list subscriptions, and now I'm even using rss2email, so I have lots of email that is not spam. I moved to IMAP and my filters are server side with sieve, but I don't have spam filtering yet. I thought I could replicate the setup easily, but it seems nobody is doing that, and everyone has the mail already scored when it reaches sieve. Seems like the "extprograms" extension would be a fit, but again, nobody seems to mention on documentation, so I'm fearing I'm probably wrong. Suggestions? Thank you very much! -- Alex (a.k.a. suy) | GPG ID 0x0B8B0BC2 http://barnacity.net/ | http://disperso.net

I am getting some panics after upgrading from 2.2.13 to 2.2.14 This panic happens for one user only, he is subscribed to 86 folders, on two of them this panic happens quite often - several times a day.
