[Dovecot] Authentication a la Postfix's Mynetworks
by Asai 05 Nov '10

05 Nov '10

Is it possible to automatically authenticate Dovecot users using the same type of mechanism which makes Postfix able to simply check SMTP users using the mynetworks variable? Basically I would like to be able to authenticate users on my designated networks automatically, and require a password for those outside this network. Is this possible? -- --asai

by Per Jessen 05 Nov '10

In my email archiving setup, no user will have an inbox (regular mail is taken care of by another system). Is it not possible to configure a dovecot setup without an inbox? /Per Jessen, Zürich

Hi all, this is my first post to this list, and hope someone can help me ;-) I'm running dovecot.x86_64 1.0.7-7.el5 on a CentOS release 5.5 (Final) box. when a user tries to create a sub-subfolder in Archiv, he gets the message: "Mailbox doesn't allow inferior mailboxes" Mailclient is MS Outlook 2003 SP3 is there a spezial configuration in /etc/dovecot.conf needed? MailLocation is by default in /etc/dovecot: # See doc/wiki/Variables.txt for full list. Some examples: # # mail_location = maildir:~/Maildir # mail_location = mbox:~/mail:INBOX=/var/mail/%u # mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n # # <doc/wiki/MailLocation.txt> # #mail_location = Users have there IMAP folders in "~/mail" # pwd /home/bema/mail # ls -l total 552 -rw------- 1 bema bema 0 Aug 9 16:21 Archiv -rw------- 1 bema bema 0 Aug 7 12:04 Aufgaben -rw------- 1 bema bema 0 Aug 4 16:05 Drafts -rw------- 1 bema bema 0 Aug 7 12:03 Gel&APY-schte Objekte -rw------- 1 bema bema 553349 Aug 7 12:05 Gesendete Objekte -rw------- 1 bema bema 0 Aug 7 11:50 Junk-E-Mail -rw------- 1 bema bema 0 Aug 7 12:04 Postausgang -rw------- 1 bema bema 887 Aug 7 12:05 Sent -rw------- 1 bema bema 0 Aug 4 16:05 Trash many thanks Richard

Came across this in the logs... Nov 3 16:08:00 bubba dovecot: imap(dmiller(a)amfes.com): Error: Attachment file /var/mail/attachments/dc/73/dc7398c85dd02efe8a14fe6cc019b2cf07eec600-d5ca962aaae7d14c587400003bc41c5f size mismatch: 122626 != 165655 There's about a dozen different file entries listed in the error log. I'm using 2.0.6, mdbox, and the mails are stored on a local XFS partition. I did recently start running xfs_fsr to defragment - could that do anything? -- Daniel

[Dovecot] sdbox-format and sa-learn(spamassassin)
by Ingo Thierack 04 Nov '10

04 Nov '10

Hello, is it somehow possible to use sa-learn on sdbox-mailboxes? Maybe i can use dsync to "mirror" the mailboxes(only the spam-subfolder) to another location and convert it to mbox or maildir and act then on it with sa-learn? I know the antispam-Plugin, but until now no success, to get it running. So I think about an way, to learn via sa-learn on an file which i can process. Regards Ingo

[Dovecot] automatic un-subscribe ?
by Per Jessen 03 Nov '10

03 Nov '10

Is there a way for an unsubscribe from a previously (auto-)subscribed folder? I'm building an email archiving system, and archived mails are organized by annum. A user will have e.g. 3 years of archive available. Currently that would mean this user would be auto-subscribed to private folders named 2007, 2008, 2009 and current. Starting January 2011 though that would change to 2008, 2009, 2010 and current. Is there a way of auto-unsubscribing 2007 ? /Per Jessen, Zürich

Hi list, can someone please explain me the following behaviour of deliver in combination with fs-quota and reading from stdin: > # repquota -a | grep ud_3p5 > ud_3p5 -- 4464 10240 12288 10 0 0 > # stat -c "%s" /tmp/mymail > 4524853 so there's enough space for this mail > # su ud_3p5 -s/bin/sh -c "cat /tmp/mymail | /usr/libexec/dovecot/deliver -e; echo \$?" > sda6: warning, user block quota exceeded. > sda6: write failed, user block limit reached. > Not enough disk space > 77 vs. > # su ud_3p5 -s/bin/sh -c "/usr/libexec/dovecot/deliver -p /tmp/mymail -e; echo \$?" > 0 Must have something to do with create_raw_stream inside deliver.c System is running Dovecot v1.2.13 Thanks, / manuel

Hi! I'm setting up a new server and migrating from Cyrus to Dovecot. What would be the most stable version to install on a production system. Would 2.x be alright? I'm feeling lucky. System is Debian Lenny. Thanks for any information! Monika -- Monika Janek Systems Administrator, Side Effects Software Toronto, Ontario Canada 416-504-9876 x207 www.sidefx.com
