Hi list, Today i tried upgrading my dovecot server from 0.99.14 to 1.0alpha3. Unfortunately the new version does not work.

[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] Still corrupt indexes in 1A4
by Alen Salamun 02 Nov '05

02 Nov '05

Hello All! Well I still have users which almost daily get corrupt dovecot files in their IMAP folders (Maildir style) and are unable to read their mail in this particular folders. When I delete dovecot files in this folder (rm -rf dove*) user can again read all messages. This is regular Linux CentOS 4.2 with SAN storage (boot from SAN) as disks. So this is EXT3 on LVM. BUT it is VERY interesting that than happens only to two users which are connected to the server via slow links (reading via Thunderbird or Squirrelmail). It never happened (now for weeks) to other 10 users which use it localy or at home (on speedy links). It's very hard for me to exactly pinpoint the problem, since it never happens to me. But when it happened to one user again I asked him to send me screenshoot of it. I could see there that SquirrelMail said: "Warning: fgets() [function fgets]: SSL: fatal protocol error in /usr/share/squirrelmail/functions/imap_general.php on line 93." Examining this file this line is in function: --------SQUIRRELMAIL PHP SOURCE------------ /** * Custom fgets function: gets a line from the IMAP server, * no matter how big it may be. * @param stream imap_stream the stream to read from * @return string a line */ function sqimap_fgets($imap_stream) { $read = ''; $buffer = 4096; $results = ''; $offset = 0; while (strpos($results, "\r\n", $offset) === false) { if (!($read = fgets($imap_stream, $buffer))) {<- THIS IS LINE 93 /* this happens in case of an error */ /* reset $results because it's useless */ $results = false; break; } if ( $results != '' ) { $offset = strlen($results) - 1; } $results .= $read; } return $results; } } ------------------------------------------- Looks like dovecot drops connection or something. Well must be related to corrupt dovecot files in particular folder, since deleting them solves the problem. BR, Alen Salamun

[Dovecot] 1.0.alpha4 released
by Timo Sirainen 02 Nov '05

02 Nov '05

The actual alpha4 release this time. With a few changes since the pre-release. The important changes again: - Default lock_method changed to flock instead of the old fcntl. Solaris users will need to set it back to fcntl. This makes sure that Dovecot's indexes aren't accidentally used with NFS. - IMAP: We might have sent extra EXPUNGE messages when output buffer got full. This could have caused various sorts of very bad behavior. This is the main reason why everyone should upgrade as soon as possible. - POP3: We sent duplicate replies for LIST command when output buffer got full. Probably caused Thunderbird's duplicate deletion bugs? (Although I thought someone checked that Dovecot's reply was correct when the bug occurred?) - pop3_uidl_format setting is now required to be explicitly set in configuration file for pop3 to work at all. I want to get rid of the old default setting which breaks Outlooks, and simply changing the default would break existing setups. - Multiple passdbs and userdbs of same type can now be added with different parameters. Some people asked about this earlier. - Authentication cache works now with other than SQL and LDAP passdbs. Some passdbs such as PAM require some additional settings to work. See example config file. - Some other fixes to authentication cache related to failure handling and non-plaintext authentication. - deny passdb wasn't working for non-plaintext authentication. New changes since alpha4 pre-release: - imap/pop3 proxy feature was broken - fixed an assert-crash in ostream-file.c that was only in the pre-release And some more changes since alpha3 that I didn't mention before: - zlib plugin updated in http://dovecot.org/patches/1.0/zlib-plugin.tar.gz to be much faster than before - Added ssl_username_from_cert setting. Not actually tested yet, does it work? - epoll was broken with 64bit systems - Added deny password databases. - Dovecot can be run from inetd again - Index breakage/crashfix related to adding new keywords

[Dovecot] Problems with dual ldap auth
by Stian Jordet 01 Nov '05

01 Nov '05

Hi, I can't seem to figure this out. Is it impossible to use two different ldap auth? It works if I use one ldap and one pam, but I do need to use ldap for both. This is from my config: auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/ldap-virtual.conf } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/ldap-virtual.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root #chroot = #count = 1 #ssl_require_client_cert = no } It works well if I only use one of them (so they seem to be correct), but together, only the last (dovecot-ldap) is used. Anyone see a reason for that? Best regards, Stian

[Dovecot] Usernames and Passwords for Virtual Users Request
by Matt 01 Nov '05

01 Nov '05

A feature I think would be nice. When a single IP hosts email for multiple domains the solution is usually to use the complete email address as the username. I have users that have migrated from Cobalt RAQ's which do not work like that. If a user trys to authenticate with just there username such as "joeb" instead of joeb(a)dirt.com I would like Dovecot to check all the domains it hosts and if it only finds one with the username "joeb" assume thats the one. If multiple domains have the username "joeb" refuse to authenticate without the "@domain" part. Perhaps this is not possible. Sure would be handy though. Oh, it would also be nice to automatically lowercase all usernames before authentication. Matt

[Dovecot] errors after 1.0a3 -> 1.0a4
by Jakob Hirsch 31 Oct '05

31 Oct '05

Hi, somebody else seeing these? Oct 21 09:14:06 ymmv dovecot: imap-login: Login: user=<xxxx>, method=CRAM-MD5, rip=84.162.151.124, lip=85.214.25.134, TLS Oct 21 09:14:07 ymmv dovecot: imap-login: epoll_ctl(): No such file or directory Oct 21 09:14:07 ymmv dovecot: child 11419 (login) returned error 89 mailbox access fails after that. Had this already yesterday, then downgraded to alpha3 and it worked again, upgraded again and it kept working. Strange thing is, access through squirrelmail works perfect, but using Thunderbird gives these errors. I'm using maildir with epoll and inotify, if that matters.
