[Dovecot] IMAP limitation
by Tom Allison 15 Nov '05

15 Nov '05

I was trying to delete a LOT of email messages in one shot from Thunderbird. I selected everything in a folder (>10,000) and then hit DELETE. I received an IMAP error. It clearly implied a limitation to just how many UIDS I can submit on an IMAP request at a time. Is this a limitation of dovecot? (I'm assuming it is). I can work around this, I think, because I haven't found a limitation to retrieving a list of email message UIDS as yet. I could thereby send splices or chunks of that list of UIDS to delete. I ran into this while trying to do a variety of obscene things in my attempts to develop a web mail application. Because of the number of strange tests I have, I don't really "blame" anything since I'm not sure that anyone really expects to delete 10,000 messages at one command.

[Dovecot] TLS negotiation from client fails after openssl upgrade
by Willem Riede 13 Nov '05

13 Nov '05

Is anyone using dovecot on Fedora fc5-devel? I had to rebuild my rpm of alpha4 due to dependencies when I pulled in openssl-0.9.8a (with a whole bunch of other updates). Now when I start my mail client (balsa) it tells me it "Cannot connect to the server: TLS negotiation failed". Dovecot wrote in maillog: "imap-login: Disconnected: rip=1.2.3.4, lip=1.2.3.4, TLS". Does anyone else see that? Can anyone advise me how to debug this? Thanks, Willem Riede.

[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] Asserion Failure in Current CVS
by Todd Burroughs 12 Nov '05

12 Nov '05

Just installed the version from CVS as of Oct. 27. I noticed three problems quite quickly: Still seeing "(imap) killed with signal 14" My INBOX closed with "access error" after reading it for a bit. There's nothing in the logs or anything, but this hasn't happened for quite a while now. There where quite a lot of incoming messages at the time and I was marking messages as deleted using pine. After reverting to the last version of dovecot that I was using and restarting pine, it opened quickly (no reindexing) and the deleted emails where marked as deleted. I don't know if this helps much ;-) The rest is a backtrace, etc. of an assertion failure: dovecot: Oct 27 16:58:12 Error: 13481 imap(username): file mbox-sync-rewrite.c: line 393 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) dovecot: Oct 27 16:58:29 Error: child 13481 (imap) killed with signal 6 (gdb) bt full #0 0xffffe410 in ??

[Dovecot] Folders mysterously deleted
by Andy Cravens 12 Nov '05

12 Nov '05

Using alpha 3 on Solaris 9. One of our users reported all folders except his inbox were missing. I went to the server and looked at the logs and could find no indication that a sysadmin had logged in and deleted the folders. Also found no indication of anything unusual in the dovecot log file. Has anybody seen a situation where dovecot deleted folders?

[Dovecot] dovecot 1.0alpha 4 error
by Alex Campoe 11 Nov '05

11 Nov '05

I tried to research this but could not find anything. Apologies if someone already reported this issue. I was running alpha 3 on Solaris 9, and having some timeout issues on lasge mailboxes. Decided to upgrade to rc4 before tweaking anything else. On rc4, when I try to start dovecot, I am getting: dovecot: Nov 10 14:04:56 Info: Dovecot v1.0.alpha4 starting up dovecot: Nov 10 14:04:57 Error: child 18805 (auth) returned error 89 dovecot: Nov 10 14:04:57 Error: Auth process died too early - shutting down dovecot: Nov 10 14:04:57 Error: auth(default): Unknown userdb driver 'passdb' No changes on .conf file. Works fine with rc3. Did I miss something?

[Dovecot] dovecot-example.conf error with POP3 UIDL format?
by Shayne Hardesty 11 Nov '05

11 Nov '05

I just installed dovecot 1.0alpha4 on a very busy RHEL4 server with about 1300 users. So far so good, except for the dreaded duplicate emails in outlook for users who use POP3 and have "leave message on server" selected. After searching the archives I found that this is usually related to the UIDL format. The example in the .conf file is this: / # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu / Note that 'v' comes first, then 'u'.. But, right under it, is this: / # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. / In this example (and the next example just under it) 'u' comes first, then 'v'. So is the first example right, in that %08Xv%08Xu is compatible with UW ipop3d, but not outlook? Or is the UW ipop3d example a mistake? For what it's worth %08Xu%08Xv seems to have fixed my users' duplication problems. Shayne

I'm running dovecot 20051026 version on Redhat4. I tried to do a stress test. However dovecot dies after I login a few hundred users.
