[Dovecot] SIS Error
by Daniel L. Miller 04 Nov '10

04 Nov '10

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

[Dovecot] Know when a Folder is Expunged or Deleted
by Alex Baule 03 Nov '10

03 Nov '10

Hi Timo and Everyone.... There is a way to know when a folder it's been deleted ? And if this folder is empty ? Let's explain why... I intercept the expunge function, to treat my files expunged, but when i expunge a folder, this function it's not called, and my emails don't get my treatment to be expunged. Basically i need to do something like this: It's empty ? No --> return OK but Dont Delete folder, because it's not empty. Yes --> Return OK and Delete the Folder to be expunged. Tks !

[Dovecot] Virtual inbox folder bug
by Antonio Henrique Oliveira 03 Nov '10

03 Nov '10

Hi all, I've been using dovecot as our internal mail server for quite some time. It works very well. Each of our mailboxes have 1000+ messages (some have more than 4-5000 messages). I have recently started using virtual folders and, using an adaptation of an example script in the dovecot site (http://wiki.dovecot.org/Plugins/Virtual) to have a virtual folder changed to act as inbox. All of my email is delivered in some folder other than the real inbox via sieve scripts. My inbox is, therefore, a virtual folder, which only displays the unread emails on all the folders in the account. Everything works fine *except* that, when I mark an email as read or when I open an email directly on the inbox, it does not disappear from the inbox (as it should since it is not unread after being open or being marked as read). I'm not sure if this is a bug, a "feature", or a misconfiguration.... :) I'm using dovecot 1.2.13 on Debian Etch (installed using the backports repository). Attached is the file with the output of "dovecot -n", the script for the virtual folder and the custom login script to change the virtual folder to act as the inbox. I'm using Thunderbird 3.1.6 on Windows XP SP3 as the main mail client and also using an Android phone (Samsung Galaxy) to access the same account. Regards, -- Anto'nio Henrique A.
