[Dovecot] C programmers, please help. need dovecot patch
by Adam M. Dunn 05 Apr '06

05 Apr '06

Hi all. Can any C programmers out there tell me how to fix Dovecot to default to Maildir format when autodecting can't find anything? I don't know C, but it seems like it would be a simple thing. Right now, I use the autodetect mailbox feature because we want users to choose to optionally be able to use Mbox format (we have some diehard unix users with non-maildir clients). I have Maildrop setup to check for the existance of a ~/Maildir folder in the user's home, and if it exists, it delivers there. Otherwise it falls back to ~/Mail where mbox style files go. The problem with Dovecot is there is no way to tell the autodetect feature what to default to, and if it can't find anything, it automatically creates a folder called ~/mail under the user's home and primes it with an Mbox file, but I'd rather it create a ~/Maildir instead. So if we have for example, a new user with no mail yet, and they log in via IMAP before getting any mail from maildrop, Dovecot will create a them a ~/mail folder. So when they DO get mail, our maildrop filters will think they are an Mbox user. I could do some fancy Maildrop filters to fix that when they get their first mail, but in the meantime the unknowing user could try creating things via IMAP that gets overwritten. Anyway, it would be much cleaner if Dovecot just did what I wanted. If anyone could point me to the place to patch my copy of Dovecot, I would GREATLY apprecieate it. I don't know C, but I know many other languages. I would also like to see this be added via the config file in future releases. So consider this a feature request. Not only that, but more control over the autodetection process in general would be REALLY nice. Thanks. Adam

[Dovecot] Setting a Default Domain
by Richard Laager 05 Apr '06

05 Apr '06

I'm working on migrating to Dovecot. At the moment, I have a mail path that includes the domain, so I'm using %d to get that. However, if users authenticate without specifying a domain (i.e. using "bob" instead of "bob(a)wiktel.com"), then %d expands to nothing. I'd like to have that expand to a default domain (wiktel.com) instead. Is that possible? Thanks, Richard

[Dovecot] About Released 1.0 alpha5 version
by Gisella Linares 04 Apr '06

04 Apr '06

Hi, I'm woking with dovecot at my work and I would want to upgrade the actual version to Released 1.0 alpha5 version, but when I saw the download section at dovecot home page, I noticed that you have only beta versions available. Because of this, I would want to ask you if since now you only put available beta versions or those of them will be replace for the next alpha version. Thanks for beforehand your gentility in the attention to the present. Regards, Gisella Linares

[Dovecot] 1.0.beta5 released
by Timo Sirainen 04 Apr '06

Just two changes: - Beta4's SSL proxying rewrite worked worse than I thought. Reverted it back to original code. - Filesystem quota plugin now looks up the mount path correctly.

[Dovecot] SSL failures on 1.0B3
by Joseph Filla 04 Apr '06

04 Apr '06

I have setup Dovecot 1.0B3, and IMAP works fine, but I cannot get IMAPS to work. I've generated the keys with the mkcert script and Thunderbird can see and accept the certificate but tosses an error just after that. In my log, I'm getting: dovecot: Apr 03 19:07:43 Warning: imap-login: SSL_accept() failed: error:140D308A:SSL routines:TLS1_SETUP_KEY_BLOCK:cipher or hash unavailable [x.x.x.x] dovecot: Apr 03 19:07:43 Info: imap-login: Disconnected: rip=x.x.x.x, lip=x.x.x.x, TLS Can anyone give me a tip as to what is the matter? I don't understand these ssl errors, Thanks, -- Joe

[Dovecot] 1.0.beta4 released
by Timo Sirainen 04 Apr '06

04 Apr '06

I haven't had yet time to read all the mails in this list which I skipped in the last few of weeks. I'll try to get to them eventually. This release contains several new features which haven't been fully tested yet, such as ACLs, master users and Maildir++ quota. If you intend to use them, test them properly first. This is the first Dovecot release where it's supposed to work well with NFS. Even with indexes being stored in NFS. I was able to test it only with Linux 2.4 kernels as clients though, and it didn't work well in a stress test. It looked like the problem was caused by the kernel caching the data a bit too much. Hopefully I can test soon with 2.6 kernels. Also note the other changes which might affect you. Especially if you're using Dovecot-LDA remember to upgrade it as well to make sure the default lock_method gets updated in it also. As for the future, it looks like I'm getting soon paid to develop several features to improve Dovecot's performance (by the company which already paid for ACLs, NFS fixes and many other changes in this release, thanks!). * Changed the default lock_method back to fcntl. Apparently flock gives problems with some systems. * mbox: mailboxes beginning with '.' are now also listed * Replaced mail_use_modules and mail_modules settings with mail_plugins and mail_plugin_dir. Now instead of loading all plugins from the directory, you'll have to give a list of plugins to load. If the plugin couldn't be loaded, the process exits instead of just ignoring the problem (this is important with ACL plugin). + Added support for "master users" who can log in as other people. The master username can be given either in authorization ID string with SASL PLAIN mechanism or by setting auth_master_user_separator and giving it within the normal username string. + Added ACL plugin with ACL file backend. This however doesn't mean that there yet exists a proper shared folder support. If master user logged in as someone else, the ACLs are checked as the master user. + Added some Dovecot extensions to checkpassword passdb, see ChangeLog + Updated passwd-file format to allow specifying any key=value fields + Maildir++ quota support and several quota fixes + passdb supporting extra fields: Added "allow_nets" option which takes a comma separated list of IPs/networks where to allow user to log in. + NFS: Handle ESTALE errors the best way we can + IMAP now writes to log when client disconnects + In shared mailboxes (if dovecot-shared file exists) \Seen flags are now kept only in index files, so as long as each user has a separate index file they have separate \Seen flags. - Fixes to DIGEST-MD5 realm handling so it works with more clients - BODYSTRUCTURE -> BODY conversion from cache file was broken with mails containing message/rfc822 parts. - Fixed several memory leaks - We could have sent client FETCH notifications about messages before telling about them with EXISTS - Compiling fixes for Solaris and some other OSes - Fixed problem with internal timeout handling code, which caused eg. outlook-idle workaround to break. - If /dev/urandom didn't exist, we didn't seed OpenSSL's random number generator properly. Patch by Vilmos Nebehaj. - Maildir: Recent flags weren't always immediately removed from mails when mailbox was opened. - Several changes to SSL proxying code, hopefully making it work better.

[Dovecot] Dovecot 1.0beta4 and Disconnected Problem
by Gerhard Wiesinger 04 Apr '06

04 Apr '06

Hello! Yesterday I upgraded from 1.0beta3 to 1.0beta4. I've major problems now with my inbox (quite large, 900MB) and another large folder. Thunderbird 1.5 connects and disconnects. I tried to delete the indexes of dovecot and thunderbird without any sucess. Finally I downgraded to 1.0beta3 and it works well again (Beta3 was running for a timeframe from when it came out and now without any problems). Config is the same as for 1.0beta3.

[Dovecot] Re: Courier to Dovecot Maildir conversion
by Roger Weeks 03 Apr '06

03 Apr '06

We went through a courier to dovecot conversion. There are a couple of things that might be causing this problem. 1. Dovecot namespaces 2. Client configuration Your namespaces might not be taking into account the fact that courier prefixed all files and directories in the maildir with a dot (.). You can get around this a couple of ways. We had almost no IMAP clients under courier, so I renamed everything in our IMAP client directories away from .files and .directories, and used a default namespace without dots. Also some clients like Apple Mail needed an IMAP prefix like INBOX. to work with courier. I had to remove those with the dovecot namespace I set up. -- Roger J.

[Dovecot] hard quota example, 1.0b3
by Jeff A. Earickson 03 Apr '06

03 Apr '06

Timo, Here's an example of the filesystem quota issue: A user was near his hard filesystem quota, so he moved some junk to his Trash folder to clear disk space. He got the following error on his IMAP client: "Internal error occurred. Refer to server log for more information. {2006-04033 11:08:44]". My setup: Solaris 9, beta3 (soon going to beta4), mbox format, IMAP only. Home directories (where IMAP folders and index files go) have filesystem quotas. Jeff Earickson Colby College
