[Dovecot] auto-detection of user mailbox type
by John Harper 23 Dec '06

23 Dec '06

The config file indicates that if mail_location is empty, dovecot will try to find the mailboxes automatically (and by implication determine if the user is using mbox or Maildir format). But if the mbox inbox is non-standard (I have procmail delivering to ~/.mail) then one needs to specify mail_location = mbox:~/mail:INBOX=~/.mail and presumably dovecot will no longer try to determine what each user is doing. I'd like to slowly convert users from mbox to Maildir (putting DEFAULT=Maildir/ in the users' .procmailrc accomplishes that from the delivery side) and have dovecot still automatically figure out which way to work, based on finding ~/Maildir (or not). Somehow I don't think mail_location = maildir:~/Maildir:mbox:~/mail:INBOX=~/.mail is going to do what I want. I saw the example on multiple mailboxes using namespaces, but I confess I'm not clear on that especially with ragard to the INBOX setting. I know I can set mail_location on a per-user basis using the userdb (eg ldap) but was hoping to avoid that. Is there a way to specify the details of the mbox configuration, but have dovecot instead use Maildir if that exists?

[Dovecot] Lazy expunge plugin
by Timo Sirainen 23 Dec '06

23 Dec '06

There's now a plugin called lazy_expunge in CVS. Instead of EXPUNGE expunging the mails directly, they're moved to a mailbox with same name in another namespace where user can still copy the mails back. Also DELETEd mailboxes are moved to another namespace. See http://wiki.dovecot.org/Plugins/Lazyexpunge for more information. This is similar to Cyrus's two phase expunge: http://www-uxsup.csx.cam.ac.uk/~dpc22/cyrus/two_phase_expunge.html

Are you using login_process_per_connection=yes or no?

[Dovecot] umask 007 ineffective with newly created Maildir message
by Steve James 22 Dec '06

22 Dec '06

This is for Dovecot 1.0.rc15 from Debian Backports on 3.1 Stable, x86; Filesystems are local reiserfs; IMAPs client is KMail 1.9.5 Non-default settings in dovecot.conf: protocols = imaps ssl_cert_file = /etc/dovecot/mail.cert.pem ssl_key_file = /etc/dovecot/mail.key.pem mail_location = maildir:/var/mail/ambrosia.plus.com/%n mail_extra_groups = mail first_valid_uid = 1000 first_valid_gid = 1000 umask = 007 maildir_copy_with_hardlinks = yes To reproduce:- 1. Using your IMAP client with two IMAP accounts, copy a message from a folder in one account, to a folder in the other account 2. See that the newly created message file is -rw------- If a message is moved between folders on the _same_ account, however, the group permissions are preserved (ie not masked off). So it seems that the umask option is ineffective when the imap daemon creates a new maildir message file. Thanks, Steve. -- BOFH excuse #400: We are Microsoft. What you are experiencing is not a problem; it is an undocumented feature.

[Dovecot] Assertion failed

We have been running 1.0-rc15 for some time on a very small set of users. We recently have increased the user population and just ran into a problem with one user. That user is using a client we apparently had not tested yet and is causing us to get these errors in the logs: [Host name, IP address, and user name are not real] Dec 21 15:23:00 [hostname] dovecot: imap-login: Login: user=<username>, method=PLAIN, rip=10.10.10.10, lip=10.10.10.11, TLS Dec 21 15:23:00 [hostname] dovecot: IMAP(username): file strfuncs.c: line 151 (p_strdup_until): assertion failed: ((const char *) start <= (const char *) end) Dec 21 15:23:00 [hostname] dovecot: child 7151 (imap) killed with signal 6 -- Steven F.

by Farkas Levente 22 Dec '06

22 Dec '06

hi, what is the current state of dovecot dbox support? is it stable, fast and usable? is it have current advantage over maildir or it will only have when it'll be optimized? is it worth to choose as a default mailbox format in a new dovecot install? thanks. yours. -- Levente "Si vis pacem para bellum!"

Doing so should apply to dbox as well? It should be an option. Big mail systems can benefit from this optimization, but many systems may not see anything noticeable. You can do a lot of cool things with your storage once you're dealing with write-once mail data, where all actions after receiving a message get written somewhere outside of where the mail content is stored... including expunges. This is a step in that direction. Bill

[Dovecot] email message size limit
by Fred Bauer 22 Dec '06

22 Dec '06

Simple question: I've discovered that dovecot's IMAP server imposes a ~5Mb limit on email message size. After a day of searching I cannot find the configuration parameter that governs this size. What is it? Or is there no such parameter? Thanks in advance, Fred P.S. ... and yes I've discovered the quota, Maildir++, etc plugin but that doesn't seem to be what I'm after.
