[Dovecot] Error purging mdbox (damaged) mailbox
by Javier Miguel Rodríguez 02 Mar '11

02 Mar '11

We are stress testing our preproduction system. One of the "evil" tests we made was putting our mailboxes filesystem in read-only in the middle of smtp(+lda) delivery. When we try to purge one of the affected mailboxes we get error like the followings: / doveadm(lbandera@mysite): Panic: file mdbox-purge.c: line 225 (mdbox_purge_save_msg): assertion failed: (ret == (off_t)msg_size) doveadm(lbandera@mysite): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943bab0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x35) [0x3b0943bb95] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943b4c3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_purge+0xe83) [0x3b0986f0c3] -> /usr/bin/doveadm [0x408d65] -> /usr/bin/doveadm [0x4093c1] -> /usr/bin/doveadm(doveadm_mail_single_user+0x9d) [0x4094ed] -> /usr/bin/doveadm [0x4096fe] -> /usr/bin/doveadm(doveadm_mail_try_run+0xb7) [0x409b37] -> /usr/bin/doveadm(main+0x2fc) [0x40dddc] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3b0881d994] -> /usr/bin/doveadm [0x408c39]/ / doveadm(leonvela@mysite): Panic: file mdbox-purge.c: line 225 (mdbox_purge_save_msg): assertion failed: (ret == (off_t)msg_size) doveadm(leonvela@mysite): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943bab0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x35) [0x3b0943bb95] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943b4c3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_purge+0xe83) [0x3b0986f0c3] -> /usr/bin/doveadm [0x408d65] -> /usr/bin/doveadm [0x4093c1] -> /usr/bin/doveadm(doveadm_mail_single_user+0x9d) [0x4094ed] -> /usr/bin/doveadm [0x4096fe] -> /usr/bin/doveadm(doveadm_mail_try_run+0xb7) [0x409b37] -> /usr/bin/doveadm(main+0x2fc) [0x40dddc] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3b0881d994] -> /usr/bin/doveadm [0x408c39]/ The mailboxes are damaged, but maybe doveadm should not crash on them, should handle the error more gracefully and exit with a error status.

[Dovecot] Dovecot+Postfix+Mysql+quotas doesn't work

Hi ! I'm using postfix with mysql, dovecot and squirrelmail for WEBMAIL In my dovecot.conf I've: plugin { quota = maildir:User quota quota2 = maildir:Shared quota:ns=Public/ quota_rule = *:storage=400M quota_rule2 = Trash:storage=100M quota_exceeded_message = Quota excedida. Por favor, exclua alguns emails! quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } In my webmail, he informs me that I'm using the percentage of quota. But I can't make the TRASH folder is ignored. That is, I can't put a higher limit on it than the others. Am I doing something wrong? Another thing. I'm not receiving message of quota exceeded.

[Dovecot] lazy_expunge, 2 questions
by Hajo Locke 01 Mar '11

01 Mar '11

Hello List, do some tests with lazy_expunge i have 2 short questions. is it possible to set folder for expunged messages to read-only so no user is possible to really delete them? i can use mdbox for expunged-folder. but would'nt it be more functional to use maildir to have possibility to delete separate mails? when using mdbox the clean up by cron would effect always multiple messages with different ages? Thanks, Hajo

[Dovecot] 1.0.15 -> 2.x upgrade for mass hosting environment
by lists＠truthisfreedom.org.uk 01 Mar '11

01 Mar '11

Hi all, We're looking at upgrading our current mail platform from 1.0.15 to 2.x to take advantage of the new director functionality. Our main concern is the number of mailboxes involved (circa. 300K) and the rebuilding of the index files, especially as it seems that once you've upgraded, rolling back requires the deletion and recreation of all indices. Has anyone worked on an upgrade like this in the past? If so, do you have any war stories you can share either on or off list? Thanks in advance, Matt

I am wanting to use a service which has to have a copy of the emails but they still need to be delivered to the users inbox. Which script and where does it need to be placed for this to work? I am not sure which version sls runs dovecot but I know that it also uses spamassasin. If anyone can help that would be great.

[Dovecot] Smart IMAP proxying with imapc storage
by Timo Sirainen 28 Feb '11

28 Feb '11

I just committed a very early initial implementation of "imapc" storage backend to v2.1 hg: http://hg.dovecot.org/dovecot-2.1 You can't really do anything except open INBOX and read mails from it, so it's currently only intended for initial testing. It sucks in many ways right now, but I'll be improving it. The idea is that you could set for example: mail_location = imapc:imap.gmail.com And then Dovecot could act as a proxy to gmail. It won't actually work currently with gmail, because there's no SSL support for outgoing connections. Currently index files are forcibly disabled, but it would be easy to enable them, allowing Dovecot to do caching locally to improve performance. In future perhaps it will also support caching message headers/bodies to avoid unnecessary traffic. Besides the mail_location setting, you'll need to also forward the user's password to imap process in "pass" userdb extra field. How to do that depends on what passdb/userdb you're using. While testing you could simply set a static password: plugin { pass = yourpassword }
