[Dovecot] [Fwd: Imap Timeouts]
by Neilw 07 Apr '06

07 Apr '06

Hi guys, So is there resolution to my query below? Is this a bug in beta3? Thanks. Neil -------- Original Message -------- Subject: Imap Timeouts Date: Wed, 22 Mar 2006 16:56:21 +0200 From: Neil Wilson <neilw(a)dcdata.co.za> To: dovecot(a)dovecot.org Hi guys, I've got a client running 1.0.beta3 on SuSe 9.3 Everything has been running perfectly since it was installed about 6 months ago, but lately they've had issues with email clients not being able to connect to the IMAP server, until they close their clients(Thunderbird & Outlook) and then re-open them. They have roughly 70 users on their network, so it sounds like it could be too many active sessions at once, but I've tried changing a few things in the config, and so far nothing has resolved this. Any help would be appreciated. Regards.

[Dovecot] lib02_imap_quota_plugin.so: undefined symbol: quota

Hi folks. We're trying to set up Dovecot with Maildir++ quotas. Operating system is CentOS 4.3 (final) X86 using Dovecot 1.0b5. After logging in, I get the following logged through syslog and the connection closes: Apr 6 10:39:36 dev3 dovecot: imap(jtest): Loading modules from directory: /usr/local/lib/dovecot/imap Apr 6 10:39:36 dev3 dovecot: imap(jtest): dlopen(/usr/local/lib/dovecot/imap/lib02_imap_quota_plugin.so) failed: /usr/local/lib/dovecot/imap/lib02_imap_quota_plugin.so: undefined symbol: quota Apr 6 10:39:36 dev3 dovecot: imap-login: Login: user=<jtest>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Apr 6 10:39:36 dev3 dovecot: child 23750 (imap) returned error 89 My dovecot.conf: protocol imap { mail_plugins = quota_plugin imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap imap_client_workarounds = outlook-idle delay-newmail } Can someone point us in the right direction? Thanks. Steve

[Dovecot] GSSAPI and virtual Users?
by S. Thias 06 Apr '06

06 Apr '06

Hi, is there a possibility to map login-names to allowed Kerberos-Principals? At the moment GSSAPI-authentication seems to work only if loginname and kerberos-principal are the same, or am I missing something? It would be really great to use GSSAPI-auth with virtual users. Thanks a lot! S. Thias

Re: [Dovecot] batch convert mbox to maildir
by Todd Piket 06 Apr '06

I did not use the the libc-client Perl bindings...sorry. I used a modified version of mb2md-3.20. It was pretty simple really. If you'd like to look at/dowload the source please visit: http://svn.dcs.it.mtu.edu/email.mtu.edu/convert_tools/tags/mb2md-release-4.… (I have my own release numbers for the whole system I wrapped around mb2md). Not a lot of documentation and there is a lot that is specific to my site, but it shouldn't be too hard to decipher and you can always ask me questions, though I'm going to take a well earned next 2 days off. If anyone is interested, the conversion we just performed has been in place for ~5 days now. Only a handful of the ~30,000 users we converted noticed we even did anything (except performance) is better (this was in large part due to the UIDL code I added to mb2md). We are now huge Dovecot fans!

[Dovecot] Overriding inbox location in passwd-like file
by Václav Haisman 05 Apr '06

05 Apr '06

Hi, I have some real users and some virtual users. The real users use mbox file as their inbox. But I'd like to use Maildir as inbox for the virtual users. (The reason is that I am actually moving some accounts from another server that already uses Maildir.) I'd like Dovecot to find Maildir in $HOME of my virtual users as their inbox. So I tried to use the following in my users.passwd file: test:{PLAIN}some_password:30003:30003::/home/vmail/domain/test:/bin/false::maildir:%h/Maildir/:INBOX=maildir:%h/Maildir/ Unfortunatelly this doesn't work and dies with this message: Mar 8 16:44:25 logout dovecot: imap(test): Ambiguous mail location setting, don't know what to do with it: /home/vmail/isc.cvut.cz/test/mbox (try prefixing it with mbox: or maildir:) Mar 8 16:44:25 logout dovecot: imap(test): Failed to create storage for '' with data: /home/vmail/isc.cvut.cz/test/mbox Mar 8 16:44:25 logout dovecot: child 41976 (imap) returned error 89 Is it even possible to override the setting from dovecot.conf like this?

[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

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
