[Dovecot] POP (dot) locks
by Christian Balzer 09 Apr '06

09 Apr '06

Hello, just to soothe my paranoia from many years of qpopper usage, which enforces solitary access to a POP mailbox. Only one login per user is possible at the same time and if a session terminates w/o qpopper being properly notified it will remain locked for some time, 30 minutes by default. With dovecot (0.99.10.4) one can login multiple times (using POP, with IMAP of course this comes as no surprise :) and thus I presume this bit from the configuration: --- # Should we create dotlock file even when we want only a read-lock? Setting # this to yes hurts the performance when the mailbox is accessed simultaneously # by multiple processes, but it's needed for reliable reading if no other # locking methods are available. #mbox_read_dotlock = no --- means that if the only other reading accesses to a (mbox style in this case here) mailbox are via other dovecot processes everything will be fine?

RE: [Dovecot] IMAP login name conversion

Unless you're authenticating from > SQL you probably have to modify the source. Let me explain: My server runs OpenBSD-3.5 and Sendmail. We host few virtual domains. Local accounts have login names in this format: login-domain_abc_xyz For example: joedirt-joedomain_com_au, info-adomain_com, info-otherdomain_com That way login accounts are unique across all the virtual domains. I use the OpenBSD pre-compiled dovecot-0.99.10p2. It is set to use "auth_passdb = passwd" and "auth_userdb = passwd" I can use mutt to access my mailbox via IMAPS with login name format joedirt-joedomain_com_au. Other users use different MUA like Outlook and prefer to login with their email addresses (joedirt(a)joedomain.com.au, info(a)adomain.com, info(a)otherdomain.com) We use squirrelmail for webmail. I modified squirrelmail to automatically convert login name from format of joedirt(a)joedomain.com.au to joedirt-joedomain_com_au. So if users use squirrelmail, they can just login with their email addresses. My question is how to achieve the same thing with other MUAs like Outlook? Do I have to modify dovecot source? Can I use LDAP or SQL instead? Note that we are using Sendmail and prefer it than othe MTA. I have looked at the Wiki, specially the "DovecotOpenLdap" but am still confused. Thanks Zoong

[Dovecot] dovecot rpms, .subscriptions file, mbox to maildir
by Saurabh Barve 07 Feb '06

07 Feb '06

Hi, I am running dovecot 0.99-14 on a Fedora Core 2 machine. I had a few questions: 1) I wanted to upgrade to the dovecot-1.0 release. However, I am not sure if that's really required. dovecot-0.99-14 has been running very well for me for quite some time. Is there a real advantage to switching to the latest release. The reason I'm asking this is because: i) I don't have too many users to server - around 15 only. ii) My mail server is a pretty fast machine (~1 GHz, 1 GB RAM) machine, so hardware isn't too much of an issue. iii) I like to install software from rpm's. It's not that I can't install from source, but installing from rpm's makes it much easier for me. Just a personal preference. The version of dovecot that I am running was obtained from Dag Wieers web site. I haven't seen a newer version there. I've googled for rpm's for newer versions, and they are available, but I don't want to install it from some third party source that I don't know/trust. iv) I am also planning to support web mail for my users (probably through Squirrelmail). Are there any advantages/disadvantages to upgrading dovecot for that? v) People use Mozilla Mail, Mail.app, Thunderbird, Outlook, and Opera. Does the 1.0 version provide better integration with different mail clients (even though I understand that sometimes it's a problem with the client implementation). So, are there newer version of dovecot (1.0-stable) available in rpm formats which are guaranteed to be safe and un-trojaned? And is there any really good reason why I should upgrade to 1.0-stable? 2) My second question is about creating the .subscriptions (or subscriptions in 1.0) file. When I moved people over from using pine to using a mail client like Evolution/Thunderbird, I had to create .subscriptions/.mailboxlist file for them so that they could see the folders that they had created in pine. However, people still sometimes access e-mail using pine. They then create new folders in pine, which they are unable to see in their mail client. Is there a way around it? This occurs especially when people check their mail at the start of the month, and pine asks about saving/deleting old sent-mail folders, Trash folders. Is there a way to add these folders automagically to the .subscriptions file? 3) Would I be able to support web mail using mailboxes in mbox format, as I have them now? Or do I have to go for Maildir format? Since our university introduced web mail, they have had two sets of folders - one with capitalization (Sent, Deleted Messages, etc.) and one without (sent-mail, etc. - these were from our pine days). Is this due to web mail? Also, if I do need to convert from mbox to Maildir, what is the standard tool for doing that? I saw at least three different tools/scripts for doing that (mbox2maildir,mb2d,mb2md-2,mb2md.pl, .. ). Which tool (and from where) should I use to convert mailboxes without problems? Any help is greatly appreciated. Thanks in advance, Saurabh. ----- sa(a)atmos.colostate.edu

[Dovecot] Dovecot, Outlook Express and new accounts
by news.gmane.org 12 Nov '05

12 Nov '05

I have come across a strange situation, involving new accounts. I am running Dovecot 0.99.10-5 on Fedora Core 2. Dovecot is configured to use pam for authentication, and the dovecot pam service is configured to use pam_mkhomedir. When an account is created and the user logs in through SquirrelMail, there is no problem. The standard folders are available - Inbox, Drafts, Sent Items and Trash. When logging in through Outlook Express first, it gives the following error:- The server did not respond to this IMAP command before the connection was terminated. Configuration: Account: mail.server Server: mail.server User name: username Protocol: IMAP Port: 143 Secure(SSL): 0 Code: 800ccc0f A packet trace shows the following:- <<< * OK dovecot ready. >>> 008E CAPABILITY <<< * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED STARTTLS AUTH=PLAIN <<< 008E OK Capability completed. >>> 008F LOGIN "username" "password" <<< 008F OK Logged in. >>> 008G IDLE <<< + idling >>> DONE <<< 008G OK Idle completed. 008H LIST "" "*" Connection to host lost. My suspicion that Outlook Express is not intelligent enough to create the folders, although the sudden connection drop might indicate a bug. If it is not a bug, is there a workaround?

[Dovecot] pop3 retr error
by Marten Lehmann 28 Jun '05

28 Jun '05

Hello, I'm getting the following error while Mozilla Mail is downloading >4000 emails: The RETR command did not succeed. Error retrieving message. Mail server xxx responded: Message is deleted. So what's the error? Can't I retrieve a message, that has been marked as deleted before? If the Mesage-ID wouldn't exist, the error message would be different. I don't know what Mozilla Mail is doing and on which message id it is failing. Also, there's no output in the logfiles. Any ideas? Regards Marten

[Dovecot] Read-only mail folders
by Chris Wakelin 24 May '05

24 May '05

Is it possible to have folders on read-only partitions in Dovecot 1.0-stable? We have a NetApp fileserver which would probably be accessed via NFS (though iSCSI is possible) and which stores readonly "snapshots" of every directory accessible as .snapshot (but usually hidden from the operating system). It would be very nice to set up a "snapshot" namespace something like :- namespace public { separator = / prefix = "#snapshot/" location = maildir:%h/Maildir/.snapshot/nightly.0 hidden = yes } so that users could recover messages from say yesterday's version of their mailbox. Unfortunately, Dovecot always seems to want to write to the directory, even when indexes are stored elsewhere (as recommended with NFS anyway, I think) using INDEX=whatever in the location line.

[Dovecot] problems with ldap auth
by Nuno Lopes 10 May '05

10 May '05

I'm trying Dovecot v1.0-test43 with ldap authentication but can't seem to make it work. I'm getting the following errors in the log: dovecot: Sep 16 19:50:09 Info: Dovecot v1.0-test43 starting up dovecot: Sep 16 19:50:10 Error: Auth process died too early - shutting down What can I do to see where the error is? I have this configuration working with dovecot 0.99.xx . And if I replace the ldap authentication scheme with another one it starts up right. Following some past mailing list sugestions I've also tried removing most of the auth modules from the compilation but it made no diference. You can see my configuration files in: http://iluvatar.portugalmail.pt/dovecot/dovecot.conf http://iluvatar.portugalmail.pt/dovecot/dovecot-ldap.conf (I've intalled the binaries in /opt/dovecot) Don't know how much more data I can provide to help finding out what the problem is here (I think this won't be enough unless there's a known bug). Thanks, -- Nuno Lopes
