[Dovecot] pop3-login segfaults (new backtrace)
by interfaSys sàrl 17 Apr '11

Hello, A while back I reported that pop3-login was segfaulting, but my traces were not very helpful. Here is a new one. Let me know if it helps. #0 0x000000080090cf91 in _pthread_mutex_init_calloc_cb () from /lib/libc.so.7 No symbol table info available. #1 0x000000080090dc9d in _pthread_mutex_init_calloc_cb () from /lib/libc.so.7 No symbol table info available. #2 0x000000080090e9c5 in _pthread_mutex_init_calloc_cb () from /lib/libc.so.7 No symbol table info available. #3 0x00000008009116ec in _malloc_prefork () from /lib/libc.so.7 No symbol table info available. #4 0x00000008009143c4 in malloc () from /lib/libc.so.7 No symbol table info available. #5 0x000000080047774c in data_stack_init () from /dovecot-2.0-hg/src/lib-dovecot/.libs/libdovecot.so.0 No symbol table info available. #6 0x00007fffffffe260 in ??

[Dovecot] 2.0.12 ipwd.c does not compile under solaris
by Roger Fujii 17 Apr '11

17 Apr '11

the new src/lib/ipwd.c introduced in 2.0.12 no longer compiles on solaris. Under solaris, the *_r routines doesn't pass in result as the last parameter and return errno - it just returns result. obviously a job for configure..... -- Roger Fujii<rmf(a)lookhere.com>

[Dovecot] Post-login script with LDAP virtual users
by Hideo GOTO 16 Apr '11

16 Apr '11

Dear sirs, I'm working on Post-login script for migrating 40K Courier-imap users to Dovecot. After reading related topics about post-login script in your documentation, mailing list, I cannot remove the problem described here-below. Is there any special config to add when users are virtual (authentication and user info is fed by LDAP server). I would be grad if anyone could give me advise. Phenomena: ========== Although the authentication and script execution is successfully done, Pop3 session is aborted just after that, leaving the following error message to syslog: /var/log/maillog: Feb 7 17:45:58 pop3migr dovecot: pop3(vuser1): Post-login script denied access to user vuser1 cf. "vuser1" is UID of a virtual account on the LDAP tree. Maildir is located at /var/spool/postfixdata/%u/Maildir, and is owned by linux local user "mailuser". Dovecot works perfect ,if post-login script configuration is commented out. Environment: Dovecot: dovecot-2.0.9 (built from source tar ball) OS: Linux / 2.6.30.10-105.2.23.fc11.x86_64 (Virtual machine on a xen server) Maidir: tested both with local file system and NFS (ext3, xfs) client: Using telnet on pop3 TCP port. All the pop3 users are virtual and does not have local login account ('authentication and user information is given by LDAP server). SMTP service is managed by Postfix: ( A single local login account is writing all mails to Maildir for all the virtual users. ) Thanks in advance.

[Dovecot] How to purge mailboxes manually [dovecot_1.2.15]
by Emilio Nacelle 15 Apr '11

15 Apr '11

Hi, we have a linux network at the office. Mainly ubuntu and debian systems. Each user has it's own mail client, thunderbird, evolution, etc. In the mail server we use as the local delivery agent, dovecot 1.2.15 and the protocol imap. The users mailbox are in the server at /var/mail. Due to some kind of problem the mails that are set for delete in the mail client are not being deleted in the mailbox (if we check the mbox the mails are marked to be purged). Unless the owner uses something lowlevel shell mail client like pine to do the purge, the mails start to pile filling the account. Is this some known bug with a fix, or is there some routine we can run as admins to actually purged the mails set for deletion? (Like the "doveadm purge" in dovecot 2.0) Thanks a lot, looking forward to your answers, Emilio P.S: we would really like not having to install dovecot 2.0 :)

[Dovecot] Released Pigeonhole v0.2.3 for Dovecot v2.0.12
by Stephan Bosch 14 Apr '11

14 Apr '11

Hello Dovecot users, It's been a while since the last Pigeonhole release. This new release adds support for the new vacation-seconds extension, which allows the vacation extension to reply more frequently than every day and allows specifying this interval in seconds instead of days. I've also fixed quite a few bugs that were reported in the last couple of months. Changelog v0.2.3: * Sieve-filter tool: finished implementing basic functionality. It is not quite ready yet, but it is available for those willing to experiment with it (needs --with-unfinished-features config to compile). Also includes man page. + Vacation extension now inhibits replies to messages from sender listed in :addresses, thus preventing replies to one of the user's other known addresses. + Vacation extension: implemented the (draft) vacation-seconds extension. This also adds min/max period configuration settings. Refer to doc/vacation.txt for configuration information. - ManageSieve: fixed bug in UTF-8 checking of string values. This is done by discarding the original implementation and migrating to the Dovecot API's UTF-8 functionality. - Sieve command line tools now avoid initializing the mail store unless necessary. This prevents sievec and sieve-dump from failing when executed by root for example. - Enotify extension: fixed inappropriate return type in mailto URI parse function, also fixing ARM compiler warning. - Vacation extension: fixed handling of sendmail errors. It produced an additional confusing success message in case of error. - Removed header MIME-decoding to fix erroneous address parsing. Applies to address test and vacation command. - Fixed segfault bug in extension configuration, triggered when unknown extension is mentioned in sieve_extensions setting. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.3.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.3.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
