I have dovecot running with sieve performing vacation autoreply. Can sieve do sql lookups for vacation messages instead of having to do flat files in the users home directory? Thank you in advance. Steve

[Dovecot] exim/kmail vs. dovecot
by Kristian Koehntopp 07 Dec '07

07 Dec '07

I am using exim via dovecot_deliver to store messages in Maildir in my $HOME. I am using kmail to retrieve stuff. Unfortunately, something in my data crashes dovecot. I was using 1.0.rc14 from opensuse, but downloaded and installed 1.0.8 from the site. Here is the crash: Dec 5 18:05:09 h743107 dovecot: IMAP(kris): file mail-index-transaction.c: line 629 (mail_index_update_flags_range): assertion failed: (seq1 <= seq2 && seq1 > 0) Dec 5 18:05:09 h743107 dovecot: child 13896 (imap) killed with signal 6 Dec 5 18:05:09 h743107 dovecot: IMAP(kris): Raw backtrace: imap [0x8006cf7d] -> imap [0x8006ce58] -> imap(mail_index_update_flags_range+0x194) [0x8004d034] -> imap(mail_index_sync_begin+0x5c9) [0x8004fb79] -> imap(maildir_sync_index_begin+0x61) [0x80021c71] -> imap [0x8002350a] -> imap(maildir_storage_sync_init+0x56) [0x80023646] -> imap(mailbox_sync_init+0x16) [0x8005d566] -> imap(imap_sync_nonselected+0x28) [0x8001b838] -> imap(_cmd_select_full+0xd7) [0x80012c47] -> imap(cmd_select+0x25) [0x80012e25] -> imap [0x800143ea] -> imap[0x8001446c] -> imap(_client_input+0x7d) [0x80014bcd] ->imap(io_loop_handler_run+0x127) [0x80073987]-> imap(io_loop_run+0x28) [0x80072ac8] -> imap(main+0x518) [0x8001d898] -> /lib/libc.so.6(__libc_start_main+0xdc) [0xb7e8d02c] -> imap[0x8000f0c1] I took the liberty to syslog() the seq numbers before the assert and indeed h743107:/etc/dovecot # grep "imap: seq1" /var/log/messages | head -3 Dec 5 18:30:18 h743107 imap: seq1 1 seq2 1 Dec 5 18:30:18 h743107 imap: seq1 1 seq2 1 Dec 5 18:30:18 h743107 imap: seq1 1 seq2 1 h743107:/etc/dovecot # grep "imap: seq1" /var/log/messages | awk '($9 < $7) { print }' Dec 5 18:30:42 h743107 imap: seq1 28 seq2 16 Dec 5 18:32:43 h743107 imap: seq1 28 seq2 16 What exactly is broken here and how can I fix that?

[Dovecot] Compiling with SQL support
by Mark Smith 07 Dec '07

07 Dec '07

Hello all, I am currently having a slight problem (ok well more likely me just not doing it right), with compiling Dovecot with MySQL support. The version is 1.0.8. I have tried running configure with --with-sql and --with-sql-drivers, but this however still does not compile MySQL support, I do no wish to install MySQL on this server, as I am using a network SQL server, but I do have the compiled source available on this server. I have tried running: gcc -shared -fPIC -DHAVE_CONFIG_H -DBUILD_MYSQL \ -I../.. -I../lib -I../lib-settings -I/data/mysql/include/mysql \ driver-mysql.c -o driver_mysql.so -lmysqlclient inside the /src/lib-sql, but this just returns an error that mysqlclient cannot be found. I have tried running dovecot --build-options, but MySQL is not listed here, the operating system is FreeBSD 6.2. The documentation does not seem to be giving any hints as to why this is not working, nor do How Tos. Any help would be appreciated. Mark Smith

I'm preparing myself for migration to dovecot 1.0.rc15 (debian stable) and would like to create indexes before users start to login into new server to ease the load. My other option is to write a script which will log as each user and create indexes, however this seems a bit of painful way to do it.

[Dovecot] Dovecot + SASL + allow_nets
by Marc Cuypers 05 Dec '07

05 Dec '07

Hi, When using dovecot for authentication of an SASL (postfix) request, i cannot use the allow_nets parameter. The IP-address of the requester is not known in dovecot. I would like to allow sasl for certain users, others are not allowed to access via SASL. Some users can have access to imap and pop3 from certain IP-addresses. How could i combine this in then dovecot configuration? -- Best regards, Marc

Looks ok, but I hate to add new settings to dovecot.conf nowadays since there are already too many. Also then there would be two Kerberos-related settings that simply set environment variables. I'm beginning to think that maybe something more generic is needed, such as: auth default { .. environment { krb5_ktname = .. krb5ccname = ... who_knows_what_else_in_future = .. } } I think LDAP library also can accept settings from environment. Anyone on mailing list have better ideas?
