Hi all, After rc10 I have problems with imap and imaps Hi all, After rc10 I have problems with imap and imaps Nov 16 15:42:39 beastie dovecot: IMAP(user1): open(/home/user1/Maildir/.MeldWelSpam/dovecot-keywords) failed: Permission denied Nov 16 15:44:09 beastie dovecot: IMAP(user2): open(/home/user2/Maildir/.MeldWelSpam/dovecot-keywords) failed: Permission denied Nov 16 15:44:09 beastie dovecot: IMAP(user2): file maildir-keywords.c: line 222 (maildir_keywords_lookup_or_create): assertion failed: (mk->synced) Nov 16 15:44:09 beastie dovecot: child 98798 (imap) killed with signal 6 Nov 16 15:46:10 beastie dovecot: IMAP(user2): open(/home/user2/Maildir/.MeldWelSpam/dovecot-keywords) failed: Permission denied Nov 16 15:46:10 beastie dovecot: IMAP(user2): file maildir-keywords.c: line 222 (maildir_keywords_lookup_or_create): assertion failed: (mk->synced) Nov 16 15:46:10 beastie dovecot: child 98819 (imap) killed with signal 6 The Permission denied messages where there in rc10 as well, but that was not causing problems. These folders are symlinks to shared spam and ham folders for spamassassin learning. Any clue on how to fix this? FreeBSD-i386 6.1-RELEASE-p10 dovecot-1.0.r13 from ports Kind regards, Spil.

[Dovecot] updated gentoo ebuild provides dovecot-sieve
by Brian G. Peterson 18 Nov '06

18 Nov '06

I'm hoping that there are some Gentoo users on this list who will chime in on a bug that is near and dear to my heart. We've created an updated Gentoo ebuild that adds a sieve USE flag and builds dovecot-sieve if the use flag is enabled. The gentoo bug is here: https://bugs.gentoo.org/show_bug.cgi?id=141743 and the ebuild is available as an attachment to that bug, or as a patch attachment (in case you're not running rc14, or just prefer the look of a unified diff) Any gentoo users on this list are urged to install from the ebuild/patch on the bug, and *report back* on the bug or this list, so that the Gentoo dev will know that it's safe to add this to portage CVS. Thank You. Regards, - Brian

[Dovecot] Dovecot LDA, LDAP, Postfix and Spawning programs..
by Jorgen Lundman 18 Nov '06

18 Nov '06

Qmail, when using LDAP, a user can specify delvieryProgramPath, or a .qmail file, to launch something like procmail. Qmail correctly setuid() to the uids set for the user in LDAP, as well as set up the common env vars (HOME, USER, MAILDIR). We moved to Postfix but found that it is quite lacking in the features supported when it comes to "virtual" users. No .forward, and if you set up an alternate transport, they are run as "any user but root, nor postfix, nor the virtual-user's uid". And worse, does not even supply the HOME/MAILDIR values to transport delivery plugin. (Forcing it to getpwnam() or similar). I have an option to make my own setuid program to query LDAP (postmap -q would work), setuid() and call, say, procmail. It has been suggested I can use "maildrop" as it can talk to LDAP. However, I picked "Dovecot" as my pop3/imap program due to an irrational dislike of Courier imap. So, if I tried Dovecot-LDA, would it support the user optionally having a ".forward" file, or perhaps the LDAP attribute deliveryProgramPath, or some other way to filter based on subject/body to sort, and/or forward, mail? If it can use LDAP, will it setuid() to the users uid (as set in LDAP, assuming I cook the LDAP conf entries correctly) when delivering(I'd hope so!) and running external filters? I am still running rc10, which works well but flips out regularly. (Previously mentioned 'too many files open' bug, some leaks in locks) I will upgrade when the LDAP changes are deemed stable.

[Dovecot] two assertion failures
by Mikhail Teterin 18 Nov '06

18 Nov '06

Hello! I was able to overcome the earlier-reported problems (of dovecot treating the standard mailboxes in /var/mail/ as directories) by specifying mail_location (continuing to use the 0.99-era dovecot.conf did not work). Then I started seeing assertion-failures like: file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) these disappeared, when I disabled mmap-access (mmap is limited to 1Gb on FreeBSD/i386), although dovecot-0.99 worked... I can now get to my mail again, but every once in a while the following assertion kills the connection: file mail-transaction-log.c: line 273 (mail_transaction_log_close): assertion failed: (log->files == NULL) Please, advise... Thanks! -mi

[Dovecot] Auth checking also the service
by Alex 18 Nov '06

18 Nov '06

Hello everyone. I'm switching to dovecot from courier-imap and after some problems with Apple Mail client, now everything seems to be fine. The only problem that I have not solved yet is to check also the service (pop3, pop3s, imap, imaps) in the authentication phase. In courier-authlib I do this: MYSQL_SELECT_CLAUSE SELECT username, \ password, \ "", \ 1002, \ 1003, \ '/vmail', \ maildir, \ quota, \ name, \ "" \ FROM mailbox \ WHERE username="$(local_part)@$(domain)" \ AND active=1 \ AND $(service)=1 where $(service) can be pop3, pop3s, imap or imaps. Is it possible to do a similar thing in dovecot? Thank you in advance, Alex

[Dovecot] Help needed
by Ricardo Dias Campos 17 Nov '06

17 Nov '06

Hi. Days ago I sent a message to this list asking for help on a problem that seemed to me to be old: dovecot hangs and dovecot-auth posts log messages like: Nov 16 17:04:39 netuno dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Nov 16 17:04:42 netuno dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Unfortunatelly when this happens the only way to recover is to restart dovecot. After I while I begun to clean the dovecot-auth processes (defunct or not) that remain in the process list and the cycle of running/hunging restart from 1 hang a day until it reaches 1 hang each 10 minutes, when I kill dovecot-auth again. I've seen some days ago some messages related to this problem but they were inconclusive, meaning that they didn't point to a solution. Any help is welcome. Thanks. Ricardo

[Dovecot] LDA Question
by Jeff 17 Nov '06

17 Nov '06

I need some advice about replacing maildrop with the Dovecot LDA. I need to replicate a setup that uses postfix+maildrop+spamassassin. We'll be using Dovecot 1rc13. In the current setup, maildrop reads a file called .mailfilter in each user's folder, then call spamassassin according to the user's preferences. The file is simple, and looks like this -- if ( $SIZE > 20971520 ) { EXITCODE=77 echo "Your email was rejected because it exceeded limit of 20 MB" exit } if ( $SIZE < 26144 ) { exception { xfilter "/usr/local/bin/spamc -u user(a)domain.com" } } exception { to "$DEFAULT/Maildir/" } What is the most straightforward way to have 'Deliver' do the same thing, without changing the way that SA gets called? Apologies in advance if this is a boneheaded question. I've been sorting through Sieve documentation and HOWTOs and I see everything but what I need.

[Dovecot] maildirsize update error?
by Maykel Moya 16 Nov '06

16 Nov '06

According to [1], Trash is a reserverd folder name. When moving a message to it, maildirsize should be update with a negative byte count. If I move a message from any folder to Trash, maildirsize gets two lines, one positive and one negative. The problem is that a user can't move messages to Trash while being overquota because the positive entry goes before the negative. I'm using dovecot-1.0rc14. Regards maykel [1] http://www.inter7.com/courierimap/README.maildirquota.html
