[Dovecot] test65 "deliver" LDA bug

Hello. I've tried to implement dovecot's deliver LDA to my home mailserver. I've run into troubles :) dovecot-deliver.conf: -- snip -- mail = maildir:%h/Maildir:INBOX=maildir:%h/Maildir mbox_read_locks = flock mbox_write_locks = flock -- snip -- when i run: deliver -d bfg < email.txt dovecot delivers message to ~/Maildir/maildir/new It acctually creates "maildir" folder inside real maildir folder. If i try to list messages via Outlook express mail client, OE reports entire folder list, but also lists one message "which no longer exists on server". If i remove ~/Maildir/maildir folder this message dissaperas from OE imap folder listing. Test scenario: 1. start dovecot 2. try to deliver message using "deliver" program (succeedes) 3. try to open INBOX via imap: Outlook Express: - reports INBOX message listing with one message, which "doesn't exist on server anymore" - the next delivery test with "deliver" LDA fails (lots of nanosleep() calls) Thunderbird: - reports that there are NO messages in INBOX - still can delivery messages with "deliver" LDA deliver strace output (search for EVIL CODE string): --- snip --- execve("/opt/dovecot/libexec/dovecot/deliver", ["/opt/dovecot/libexec/dovecot/deliver", "-d", "bfg"], [/* 42 vars

[Dovecot] Another imap crash...
by Todd Burroughs 26 Mar '05

26 Mar '05

The segfault problem that was happening seems to be fixed. I'm still getting some "(imap) killed with signal 6" errors. I just noticed that it did get one segfault. Unfortunately, I don't have a core file. I'll try to get one if this happens again. Here's the error messages, not sure if it will help. I'm using the CVS copy from March 24. dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index cache file /mailhome/new/s/support/.imap/INBOX/dovecot.index.cache: indexid changed dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted transaction log file /mailhome/new/s/support/.imap/INBOX/dovecot.index.log: invalid indexid (1111832898 != 1111831599) dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index file /mailhome/new/s/support/.imap/INBOX/dovecot.index: Record UIDs are not ordered dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted transaction log file /mailhome/new/s/support/.imap/INBOX/dovecot.index.log: invalid indexid (1111831599 != 0) dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index file /mailhome/new/s/support/.imap/INBOX/dovecot.index: Record UIDs are not ordered dovecot: Mar 26 05:28:20 Error: child 4282 (imap) killed with signal 11 Todd Burroughs

[Dovecot] quota issue POP3
by Obantec Support 26 Mar '05

26 Mar '05

Hi Just u/g to RH FC3 from RH8.0 which seemed to work fine with quotas. I have quotas for usernames set up as /home/domain/domainX/username/ for web space 50MB say 48MB used so 2MB free and /var/mail/spool/username for email. 100MB (60MB used so 40MB is available). /var/mail/username is symbolic linked via to spool/mail under /var dovecot seems to be using the quota for /home/.. and sees only 2MB so refuses to write file back. maillog is reporting (username and IP replaced). Mar 16 13:20:03 proteus2a pop3-login: Login: username [11.22.33.44] Mar 16 13:20:03 proteus2a pop3(username): Error rewriting mbox file /var/mail/username: Disk quota exceeded Mar 16 13:20:03 proteus2a pop3(username): write() failed with mbox file /var/mail/username: Disk quota exceeded i am assuming this is when pop3 login is trying to re-write file back when deleting emails.

[Dovecot] Postfix SMTP AUTH patch updated
by Timo Sirainen 25 Mar '05

25 Mar '05

There was a small protocol change in later 1.0-test releases which made the older patches not to work. Updated the patch for Postfix 2.1.5 and added patch for Postfix 2.2.1. I also tested that it works with Dovecot 1.0-stable releases. So, if you're interested: http://dovecot.org/patches/postfix/

[Dovecot] Segfault in imap process
by Todd Burroughs 24 Mar '05

24 Mar '05

We've been testing dovecot for a while and I noticed yesterday that imap crashes quite often. It seems to be about even with SIGABRT and SIGSEGV. This one was SIGSEGV. Our system is SuSE Linux 9.2, 2.6.11.5 kernel (also happened with an older 2.6 kernel). Dovecot version is 1.0-test64 and was compiled with: "./configure --prefix=/services/dovecot --disable-ipv6" It's using mbox over NFS and I've configured "mmap_disable = yes". The mailbox that it crashed on is one of our support mailboxes and it is pretty busy. In the last 1/2 hour, it received over 100 emails. I had a look at the code, but didn't notice anything obvious. Thanks for any help... Here's the log messages: dovecot: Mar 22 18:22:23 Error: 19697 IMAP(support): UIDVALIDITY changed (1111532787 -> 1111533642) in mbox file /mailhome/new/s/support/mbox dovecot: Mar 22 18:22:26 Error: child 19697 (imap) killed with signal 11 and a backtrace: mail201:/services/dovecot/var/log # gdb /services/dovecot/libexec/dovecot/imap imap.core.pid19697 GNU gdb 6.2.1 Copyright 2004 Free Software Foundation, Inc.

Fw: [Dovecot] Auto Create Folders
by Chris L. Franklin 24 Mar '05

24 Mar '05

>> the problem might be: what would your mta do if: >> 1. the user never logged in via imap okay, so then they would never get there mail ? I guess I don't see where your going with this problem. >> 2. therefor no folders were created by dovecot .... Ok ?? >> 3. it has to deliver a spam message to the spam folder. Your right the filter would put it into the spam folder, witch it would created if it's not found. And as a side note the "Spam" folder was just a example folder name. Really for are needs it would be a folder called "Meetings" >> "so you have to ensure the folder existance at the user creation level >> imho. thats the logical point to do exactly that. >> checking for folder existance everytime a user might access a service is >> stupid. it costs at least a stat() call per directory." Some how you missed the part.I'd like to make sure this use always has this folder. Aka if they delete it, I'd like it to be recreated. PS. In the end all's it comes down to is i was wounder if there was a way to have dovecot auto create a folder or a list of folders at login. OR really if there was a way to tell dovecot a list of folders a user COULD NOT delete (But could delete the folders in side). -- Chris L. Franklin --

[Dovecot] automatic flag updates
by Aaron VanDevender 24 Mar '05

24 Mar '05

Is there a way to get dovecot to send automatic flag updates? I notice that when I have two clients connected and one of them reads a new message, the server sends a status update which contains the number of unseen messages, but doesn't specifically say which ones have changed. I think the solution to this problem, while not wasting bandwidth, is to issue a unilateral FETCH FLAGS response whenever a flag changes. There doesn't seem to be a way to get dovecot (I'm using 0.99.10) to do this. Can the 1.0-test versions do this? cya .sig

[Dovecot] Hide non-accessable folder from users
by Remy Zandwijk 22 Mar '05

22 Mar '05

Hi all, In our faculty, people keep asking about shared mail folders. With Dovecot up and running this should be no problem. I think we will have about 50 shared folders. I did take a look at the various solutions, but not all of them are useable. For example, I do not want users to create sub-folders in shared folders. This means the symlink option is unuseable. In my opinion, the easiest solution is creating a namespace and create the shared folders in the location of this namespace. Every shared folders gets his own UNIX group ID. Offcourse, this works great. The ony big disadvantage is that every users 'sees' all shared mailfolders, even if the user does not have the proper rights to access the folders. Is there a way to hide the non-accessable folders from users? Best regards, Remy Zandwijk
