[Dovecot] dovecot/postfix+vda

Hi guys, Been fighting with postfix+vda/dovecot/ My postfix delivers the emails to /vmail/ which is owned by user maild:users 501(uid):100(gid) without any problems. When I... # telnet localhost 110 +OK Dovecot ready. user samichand +OK pass wordpass +OK Logged in. -ERR [IN-USE] Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2007-09-05 16:32:52] Connection closed by foreign host. I get...

I need to set the mail user that dovecot uses to access the maildir to the same uid that postfix uses, how can I do this, I've read the wiki over and over and although it says you can do it, I don't know how. Taken from the WIKI... http://wiki.dovecot.org/UserIds#mailusers Virtual users where all Dovecot users run under a single system user, for example vmail (just NOT dovecot). Also taken from WIKI http://wiki.dovecot.org/VirtualUsers You can create for example one vmail user which owns all the mails, or you can assign a separate UID for each user. See UserIds#mailusers for more information about different ways to allocate UIDs for users. All I want is to be able to access the mail, with the same my "virtual_uid_maps = static:501"(set in my postfix main.cf) All of these say it can be done, but how do I do it? Please could someone assist me :( Thanks. Neil -- This email and all contents are subject to the following disclaimer: http://www.dcdata.co.za/emaildisclaimer.html

[Dovecot] Quota bug in deliver?
by FORMER 03 | Baltasar Cevc 06 Sep '07

06 Sep '07

Hi, I may be wrong, but I suspect a bug in dovecot deliver when using quotas. I've put some mails into a mailbox and then reduced the quota, to have the mailbox be over quota - here's the quota informaiton: [...] 2 getquotaroot INBOX * QUOTAROOT "INBOX" "" * QUOTA "" (STORAGE 880 5) 2 OK Getquotaroot completed. [...] When I have a setup with quotas only in the database, everything works as expected and deliver denies the message: Sep 5 21:50:14 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905195014.9D874239C007(a)ms4.srv.hoster03.de>: save failed to INBOX: Quota exceed ed Sep 5 21:50:14 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905195014.9D874239C007(a)ms4.srv.hoster03.de>: Rejected: Quota exceeded When I put a standard quota into the config as follows, the delivery succeeds (apparently deliver checks the standard quota, while IMAP correctly checks the quota from the database if it is returned. Sep 5 21:46:11 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905194611.9FE49239C007(a)ms4.srv.hoster03.de>: saved mail to INBOX The mailbox is still over quota here, but deliver does not seem to notice. == standard quota in the config plugin { quota = maildir:storage=102400:messages=1000 [...] } In case I've overlooked something, please let me know. Otherwise let me know if you need some more information. Baltasar _____ FORMER 03 GmbH _____ www.former03.de _____ fon 089.322112.0

[Dovecot] securing dovecot proxy connections
by bill-dovecot＠carpenter.ORG 06 Sep '07

06 Sep '07

The wiki <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy> page says this: "The connections created to the destination server can't be TLS/SSL encrypted.". Hrmm. Right now, with perdition, I'm forcing the use of STARTTLS on the internal connections. I'd just as soon get rid of perdition (to have one less moving part in my architecture), but I need the secure connections. Is there a way to configure dovecot's internal proxy connections to use STARTTLS or some other SSL/TLS level of security? (Without a bunch more research, I don't know what the interaction is between the real client, the dovecot proxy, and the destination server.) -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] How do I use sieve to move bounces?
by Jef Driesen 06 Sep '07

06 Sep '07

How can I use sieve to move bounces and non delivery reports (i.e. anything with an empty envelope from) to a special mailbox? I placed this snippet at the start of my sieve script require ["envelope", "fileinto"]; if envelope :is "from" "" { fileinto "INBOX.Reports"; stop; } But mails are not moved to the reports mailbox, and they are still processed by the rest of the script.

[Dovecot] OT Project idea: IMAP plugin for Google Desktop
by Kenneth Porter 06 Sep '07

06 Sep '07

Posting here, as Dovecot seems to be the premier IMAP server available. In case anyone is looking for something to work on, I found today that Google Desktop only understands email clients that keep mail on the client, and it would be nice if there was a plugin that understood IMAP. Here's a site that seems to explain how to write such plugins: <http://www.plugindevelopment.com/>

[Dovecot] Dovecot Imap Stopped working
by Duracom Lists 05 Sep '07

05 Sep '07

Dovecot has been working fine for months. We are using 1.0. Come in to work today and dovecot quit working POP3 and IMAP. I restarted the service and everything started working except IMAP? We use Dovecot as an authentication method for outgoing mail and it works. I can't telnet to myhostname.com 143, Squirrelmail will NOT work either. Where is a good place to start looking for signs of the problem. When we restart we get no errors, which is strange? K

[Dovecot] alert function (possible WIBNI)
by Stewart Dean 05 Sep '07

05 Sep '07

The imapd spec has a provision for an alert pop-up of any ASCII text message contained in /etc/imapd.alert on the IMAP server. Can I assume this is implemented on DC? It'd be real nice if in addition to the current all-users message, it was possible to do a per-user alert...but I guess that would be something for IMAP standards....... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[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?
