[Dovecot] namespaces...
by John Doe 22 Aug '08

22 Aug '08

Hi, I am new to dovecot and I am a bit confused with how namespaces/prefixes/separators are handled by the clients and dovecot... I tried to understand the desciption from the conf file but without success. With each conf I create the following path /f1/f2 on the client (thunderbird) and get the following on the dovecot server: PREFIX= and separator=/ => .INBOX.f1.f2 + .INBOXTrash PREFIX=INBOX/ and separator=/ => .f1.f2 and no Trash PREFIX=INBOX. and separator=. => .f1.f2 and no Trash Could someone point me to some IMAP for dummy web page...? ;D Or, what is the best conf able to handle most clients? Thx, JD

[Dovecot] Distributed indexes, maildir_copy_preserve_filename, and Microsoft
by Jack Stewart 22 Aug '08

22 Aug '08

Hi, I've just completed a migration from Courier to a Dovecot 1.0.7 (patched RHE 5) which is working great, except for this weirdness of an issue that is impacting a handful of users. My question is that will turning off maildir_copy_preserve_filename help or hurt in a situation where there are multiple servers with their own local INDEX files (uidlist is shared)? The problem is that a few users on a few versions of Microsoft Mail clients are not showing a few messages. They can see the messages just fine in webmail and other, more typical, E-mail clients. I know that the right solution is to upgrade to 1.1.2 and use shared indexes. The plan is to upgrade in a month or so. In my defense, this setup was not of my making, The two things issues that might have an impact are that we have shared (NFS) maildirs on multiple servers with their own local indexes and maildir_copy_preserve_file turned on. The uidlist (CONTROL) is shared and we have sticky connections turned on in our load balancer. The vast majority of clients do not have this issue. Quite frankly I have no idea these clients are ignoring the dovecot-uidlist. Would turning off maildir_copy_preserve_filename help with this setup? Another option might be easier is to delete the users INDEX and let the clients rebuild them. Since this is only a handful of users and we are migrating to 1.1.2 anyway, my preference is to make the bare minimum of changes to help address this problem. The changes need not be perfect nor anytime more than a suggestion or preference. I just want to make things better for a little while. Many thanks in advance. ---Jack P.S. The performance improvement is amazing - anywhere from 2X to 12X depending on what metrics you are looking at. It isn't an apples to apples comparison since we upgraded the servers as well but the "old" servers are pretty powerful beasts. -- Jack Stewart jstewart(a)caltech.edu / 626-395-4690 http://www.imss.caltech.edu

[Dovecot] Option to evaluate IMAP prefixes relative to $HOME, rather than the IMAP root?
by David McBride 22 Aug '08

22 Aug '08

Greetings, Is there a mechanism (or relatively small source-code change) which would cause Dovecot to evaluate IMAP prefixes relative to $HOME rather than the configured IMAP root? * * * Background: We're currently migrating from a WU-IMAP mailserver configuration which stores user mail in a global NFS-exported $HOME, and we've run into well-known issues handling client-specified IMAP prefixes. If a user specifies an IMAP prefix, Dovecot evaluates the path given relative to the IMAP root path specified in mail_location, rather than resolving it relative to the user's home directory as our old WU-IMAP installation would do. (For example: if a user has been keeping their mail in $HOME/foobar, and mail_location's folder path is set to %h/mail, then when that user comes to retrieve their mail with an IMAP prefix set to "~/foobar", then Dovecot will attempt to return the contents of the folder $HOME/mail/~/foobar -- which doesn't exist -- rather than $HOME/foobar.) At the moment, we have several hidden namespaces set up to support various common user-side variations -- "mail/", "Mail/", "~/Mail/", etc. -- each with a different custom mail_location string. Whilst this works for these common cases, it's fairly ugly, and results in extra empty directories appearing in users' $HOME. If there was some mechanism for telling Dovecot to evaluate IMAP prefixes relative to $HOME rather than the mail folder root specified in mail_location, that would provide us with a much neater and general-purpose solution. (I was hoping that setting full_filesystem_access=yes would do this, but it only relaxes the normal access permissions.) Cheers, David -- David McBride <dwm(a)tastycake.net>

Hi, I'm new here in the list so Hello to everyone! I'm compiling dovecot 1.0.10 with pam support in SLES 9 but i'm getting errors in config.log and it won't compile with pam support.

[Dovecot] assertion failed
by CJ Keist 22 Aug '08

I haven't heard anything on this bug. Is this a bug? I'm using dovecot 1.1.2 with the following patch applied: http://hg.dovecot.org/dovecot-1.1/rev/d674c05d725d Another section from my logs. I know the backtrace is just numbers, let me know how to compile to get more useful information if you need it. So far no one is beating down my door, so I don't think users are seeing any ill effects. But I would sleep better knowing why it's happening.

Hello Dovecot guys! I want to play with dovecot login processes invoked from inetd superserver, but cannot run auth worker for postfix sasl and deliver process in this case. Any ideas? WBR, mike
