[Dovecot] Dovecot hard link problem
by 도원철 01 Jun '08

01 Jun '08

My company recently changed mail server from cyrus to dovecot. The problem is that dovecot does not support hard links for message files with same message ID. I turned on the ‘maildir_copy_with_hardlinks’ option in dovecot.conf, but it does not seems to have relation to this problem, am I misunderstood? Hard links are created when move or copy messages from one folder to other folder, but when deliver creates messages this option does not works. Our mail storage will be exhausted in few days. If you have some idea to solve this problem, please please help me. Or If you fix this problem, I will happily pay for it at reasonable cost. I installed dovecot 1.0.13 and postfix 2.5.1. Best regards, WonChul,Do

[Dovecot] Segfault in imap_bodystructure_write when searching
by Christer Mjellem Strand 01 Jun '08

01 Jun '08

Whenever I try to search on my dovecot test install, dovecot dies. It immediately spawns a new process, which the client tries to connect to, and send search commands to, causing that to die, and so forth. This loop means I have to kill either the server or the client. Running Dovecot 1.0.13 from/on Debian testing, rebuilt with vpopmail support and no other source changes. Vpopmail version is 5.4.25, latest stable. Client is Mulberry 4.0.8, and the crash seems to occur whenever any type of search is performed, be it subject, sender, body etc. Otherwise the server behaves fine. dovecot -n output: # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S listen: *:9000 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes login_max_processes_count: 256 first_valid_uid: 89 mail_location: maildir:~/Maildir mail_debug: yes dotlock_use_excl: yes maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_drop_priv_before_exec: yes mail_plugins: quota imap_quota imap_client_workarounds: outlook-idle delay-newmail auth default: user: vpopmail verbose: yes passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir Anonymized log excerpt: May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:24 betty dovecot: child 21748 (imap) killed with signal 11 May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:24 betty dovecot: child 21752 (imap) killed with signal 11 May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21753 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21759 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21774 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21775 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21776 (imap) killed with signal 11 ...

[Dovecot] fetchmail on demand
by Graeme Vetterlein 31 May '08

31 May '08

I hoping this is an RTFM ... and somebody can point me at the correct 'FM' :-) I've just spent a while setting my new Debian , allways-on box in what I suspect is a generally useful configuration. I have fetchmail(1) collect mail from many mailboxes via pop3. I store these mails in different mboxs according to rules in procmail(1) I then offer these out to the household via imap in dovecot(1) . I have fetchmail(1) set to poll the ISPs every 5 minutes, this seems to work fine, but there are two issues: 1: The constant polling keeps the disk spinning for no good reason (most of the time) 2: If I check my mail via a mail reader using imap to the local mboxes ...there could be mail sitting on the ISP servers I don't see (for 5 mins) Now what would be much nicer, would simply be to have dovecot(1) issue the fetchmail(1) command whenever it it got an imap request. I general what I guess I would like is: "When a request comes in (via imap) fork off a command who's name is given in the conf file. ... imap_pre_cmd="xxx" -- Graeme

[Dovecot] Sieve Editheader Extension?
by Michael K Sanders 31 May '08

31 May '08

I've done extensive searches, and there is virtually no information about actual implementations of the draft Sieve Editheader Extension (which provides 'addheader' and 'deleteheader' actions): http://www.ietf.org/internet-drafts/draft-ietf-sieve-editheader-11.txt Is anyone currently working on this for Dovecot Sieve? If not, are there any plans to do so? And before I start digging through the source, is the architecture amenable to this functionality? Thanks, :: Mike ::

[Dovecot] Web-based shared calendar synchronizable with Outlook
by Samuel HAMEAU 30 May '08

30 May '08

Hi, I know this request is a a little off-topic but may be interesting for dovecot users (at least i hope!) Does anybody has already had an experience with a calendar sharing solution including a webcalendar and an outlook connector, "compatible" with dovecot ? Today, there are many projects aiming to be a "M$ Exchange Killer" (such as Zimbra, OBM, open-exchange, etc) but they offers a global package with MTA and imap server included. I saw the page about BynariConnector (http://wiki.dovecot.org/HowTo/BynariConnector) but unfortunatly they do not provide a webmail :( I'm afraid What I am looking for is a shared agenda solution providing a webcalendar, an outlook connector and eventually a pda connector, using (or not) dovecot, and a corporate ldap server... What are you guys using ? sam
