[Dovecot] (no subject)

Hey All, I'm developing a site on a VPS that comes stock with dovecot 1.2.17 and I'm trying to setup some functionality that is very specific to our business model. My question is this: How do I create (programatically) aliases for a forwarder? I have an address, email(a)domain.com that gets sent to a php script and I want users to be able to send to that script via any number of different names (could ultimately be 1000's). I'm thinking that I append/delete from the etc/aliases file and then run #newaliases So that email(a)domain.com will answer on dummy(a)domain.com or dothis(a)domain.com, once the email comes in, I can check the header, get who it was really sent to, do all my checks, perform the necessary action blah blah blah... and be able to do it all on one piece of code (my fantasy LOL). Am I on the right track here or is this simply not going to work? Thanks, Pete

[Dovecot] AUTH PLAIN fails while AUTH LOGIN succeeds with Exim -> Dovecot SASL auth
by Sandro Tosi 29 May '12

29 May '12

Hello, we're trying to setup a platform with authenticated SMTP with exim and relying on dovecot as auth agent. We've read http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL and so made the changes mentioned there, also setting auth_mechanisms = plain login in conf.d/10-auth.conf . With this setup, we're able to use AUTH LOGIN method on an SMTP session, but using AUTH PLAIN fails. What we receive in the SMTP session is: auth plain `echo -e -n `\0user\0password' | mimencode` 535 Incorrect authentication data (it's actually the output of that command that we put there), and in the dovecot log we see: 2012-05-24 15:04:20 auth: Debug: client in: AUTH 1 PLAIN service=smtp secured rip=127.0.0.1 lip=127.0.0.1 nologin resp=<hidden> 2012-05-24 15:04:20 auth: Info: plain(?,127.0.0.1): invalid input Do you know where we can look to resolve this problem? If you need any further information/test feel free to ask. Thanks in advance? -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

[Dovecot] Released Pigeonhole v0.3.1 for Dovecot v2.1.6
by Stephan Bosch 27 May '12

27 May '12

Hello Dovecot users, It's been a few months since the last Pigeonhole release. The main reason is that I've introduced a few big new features. Although the new features themselves probably haven't seen much testing so far, I'm now pretty confident that existing configurations are not broken by these changes. The biggest change is the addition of dict support for Sieve script retrieval. It now possible to fetch Sieve scripts from an SQL database using the Dovecot dict facility. Read the INSTALL file and the referenced additional documentation for more information. Note that this feature currently is not usable with sieve_before/sieve_after and ManageSieve. Additionally, it is now possible to specify multiple sieve_before and sieve_after scripts. This for instance enables administrators to specify both global and user-specific scripts that are to be executed before and after the user's personal script. User-specific scripts configured in sieve_before and sieve_after can not be seen or changed through the ManageSieve protocol. Finally, as promised a while back, I've incorporated the vnd.dovecot.duplicate extension into the main Pigeonhole package. Using this Dovecot-specific extension it is possible to detect duplicate deliveries (such as for example caused by mailing list subscriptions). The detection is based on the message ID and uses the same database file (~/.dovecot.lda-dupes) as the vacation extension. Since the changes introduced in the release are rather large, I strongly advise you to experiment with it a bit before deployment. Changelog v0.3.1: * Added support for retrieving Sieve scripts from dict lookup. This means that Sieve scripts can now be downloaded from a database. Compiled script binaries are still put on disk somewhere if used. The INSTALL documentation is updated with information on this new feature and the (backwards-compatible) changes to the configuration. Note that his feature is currently not supported for sieve_before/sieve_after or script management through ManageSieve. + Incorporated the sieve_duplicate plugin into main Pigeonhole tree as a normal extension (vnd.dovecot.duplicate). This Dovecot-specific extension adds the ability to check for duplicate deliveries based on message ID. Specification can be found in: doc/rfc/spec-bosch-sieve-duplicate.txt + Added support for specifying multiple sieve_before and sieve_after paths. This adds much more flexibility to the multiscript configuration. One application is to have user-specific Sieve scripts outside the user's normal control through ManageSieve. + Added a "session ID" string for managesieve connections, available in %{session} variable (analogous to Dovecot change). - Fixed several small issues, including a few potential segfault bugs, based on static source code analysis. - ManageSieve: changed use of EPROTO error to EIO in ManageSieve string stream implementation because it is apparently not known in BSD. - Gave stamp.h.in (needed for autotools) some content to prevent it from disappearing in patch files. - Fixed bug that caused a SunStudio CC compile failure (reported by Piotr Tarnowski). The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.1.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.1.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Checkpassword Perl LDAP Implementation
by Jeff Hardy 27 May '12

27 May '12

A few years back I hacked up a perl chkpassldap.pl script to authenticate against ldap, and optionally authorize against groups and/or ldap attributes. This works with both qmail and Dovecot, and it also supports a somewhat generic method to alter the environment suitable to use for Dovecot as a prefetch userdb. Anyway, I have been running the script on a qmail-ldap and Dovecot 1.2 proxying cluster using the stock qmail-ldap attributes without any troubles, and figured I would finally release it in the thought someone might find it useful. http://fritz.potsdam.edu/projects/chkpassldap I tried to document the ins and outs of userdb configuration. If anyone finds anything that could use correction or clarification, please let me know. It has been awhile since I was in the middle of it all. Cheers, -Jeff -- Jeffrey Hardy Network / Systems Administrator hardyjm(a)potsdam.edu

[Dovecot] Dovecot usage values differ from actual disk usage
by Daniel Parthey 26 May '12

26 May '12

Hi, in my dovecot setup the accounting database table shows wrong values which do not correspond with the actual disk space used. The disk usage says 2.6 Gigabytes: mail01:~# du -sh /mail/dovecot/example.org/username 2.6G /mail/dovecot/example.org/username While the doveadm quota get says 7 Gigabytes for the same user: mail01:~# doveadm -f tab quota get -u username(a)example.org Quota name Type Value Limit % User quota STORAGE 7065208 - 0 User quota MESSAGE 282024 - 0 mysql> select * from dovecot.dovecot_usage where username="username(a)example.org"; +----------------------+------------+----------+ | username | storage | messages | +----------------------+------------+----------+ | username(a)example.org | 7234773131 | 282024 | +----------------------+------------+----------+ 1 row in set (0.00 sec) What might be the reason for such huge differences (several gigabytes) between storage value in dovecot_usage table and disk usage value? After a quota recalc everything is correct: mail01:~# doveadm quota recalc -u username(a)example.org mail01:~# doveadm -f tab quota get -u username(a)example.org Quota name Type Value Limit % User quota STORAGE 2630434 - 0 User quota MESSAGE 100714 - 0 mysql> select * from dovecot.dovecot_usage where username="username(a)example.org"; +----------------------+------------+----------+ | username | storage | messages | +----------------------+------------+----------+ | username(a)example.org | 2693565239 | 100714 | +----------------------+------------+----------+ 1 row in set (0.00 sec) How can I keep the accounting data consistent with actual disk usage, without running a recalc cronjob every few hours? There's running a dovecot director and mailbox instance on each of our servers with the mails being stored on NFS and received from postfix via LMTP through the director lmtp port 20024. Configuration of director (dovecot-director.conf) and mailbox (dovecot.conf) is attached. Kind regards Daniel

[Dovecot] Valid config for lda_mailbox_autosubscribe with dovecot 1.2?
by Joan 25 May '12

25 May '12

Hi, Due to some reasons I've to support both dovecot 1.2 and dovecot 2.x, and I just found that the -s parameter I used to autosubscribe to sieve folders doesn't exist anymore in dovecot 2.x The problem arises because (AFAIK) in postfix's master.cf you can only specify one configuration, and I used to have this: dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} -s Is there any way to make the config compatible for both versions, achieving the autosubscribe and not crashing dovecot?

I would like use sieve to split up my saved mail into different folders. I have tried to find out how to do that, but failed. The IMAP server is dovecot 1.2.15 on ubuntu 11.04. The mail is stored in mbox folders. I have shell access. -- Fredrik Stax\"ang | rot13: sfgk(a)hcqngr.hh.fr This is all you need to know about vi: ESC : q ! RET

[Dovecot] Berkeley DB with Dovecot
by Jerry 23 May '12

23 May '12

I have a friend who is preparing to set up a small Postfix/Dovecot mail system. There are only approximately 25 users. He wants to use Berkeley DB in a similar fashion to the way Postfix does. I told him I do not believe Dovecot supports that. I could not find any documentation relating to it. 1) Does Dovecot support Berkeley DB? 2) Are their any plans to incorporate that feature into Dovecot? It seems like it could potentially be a very useful feature. I have used it myself when a full blown MySQL configuration seemed like over-kill on other small projects. -- Jerry ♔ Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] sieve
by upen 22 May '12

22 May '12

Hi, I'd like to keep all emails coming from alom-alert@anydomain and not forward those but rest of the emails will be kept and forwarded as well. I put following in the .dovecot.sieve if header :contains "Sender" "alom-alert@" { keep; if not header :contains "Sender" "alom-alert@" { redirect "my@emailid on server"; redirect "xyz(a)gmail.com"; redirect "abc(a)tbc.edu"; stop; } } Is this correct? Thanks, UG
