[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?

[Dovecot] LIST problem with Dovecot1.1beta10
by Dean Brooks 04 Dec '07

04 Dec '07

Hi, Certain IMAP folder problems started popping up with Squirrelmail with the 1.1beta10 version of Dovecot (and possibly earlier versions). Looked into it and I am seeing odd behavior with the LIST command. Here is how to reproduce problem, unless I'm missing something obvious: a001 login dean <password> a001 OK Logged in. a002 list "" * * LIST (\NoInferiors \UnMarked) "/" "Sent" * LIST (\NoInferiors \UnMarked) "/" "Trash" * LIST (\NoInferiors \UnMarked) "/" "Drafts" * LIST (\NoInferiors \UnMarked) "/" "INBOX" a002 OK List completed. a003 list "" Trash* * LIST (\NoInferiors \UnMarked) "/" "Trash" a003 OK List completed. a004 list "" Trash a004 OK List completed. <*** What? Shouldn't it have listed Trash instead of returning nothing?> a005 list "" Trash" <*** Unbalanced quote causes total lockup! It appears that Squirrelmail, and possibly others, are using the LIST command to test for the presence of a mailbox, but it seems impossible to get an exact match. Am I missing something here? -- Dean Brooks dean(a)iglou.com

Hi Timo, I have installed 1.1 beta 10 today with squat enabled. When I do uid search body "something", the imap will sometimes segmentation fault, or sometime hang. Here is what i found in the log when imap did not hang.. dovecot: Dec 04 17:11:07 Panic: IMAP(joewong99:joew.outblaze.com): file squat-uidlist.c: line 178 (uidlist_write_array): assertion failed: ((uid & ~UID_LIST_MASK_RANGE) >= prev) dovecot: Dec 04 17:11:07 Error: IMAP(joewong99:joew.outblaze.com): Raw backtrace: imap [0x80ca1f0] -> imap [0x80ca0fc] -> /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so [0x11b9a9] -> /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so [0x11ba7a] -> /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so [0x11bb6b] -> /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so(squat_uidlist_build_add_uid+0x2e2) [0x11c0d2] -> /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so [0x11a9cb] -> /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so [0x11acf0] -> /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so(squat_trie_build_more+0x16a) [0x11ae6a] -> /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so [0x117b54] -> /usr/local/lib/dovecot/imap/lib20_fts_plugin.so(fts_backend_build_more+0x2e) [0x1125de] -> /usr/local/lib/dovecot/imap/lib20_fts_plugin.so [0x113f3d] -> imap [0x805d196] -> imap [0x805d518] -> imap(io_loop_handle_timeouts+0x10b) [0x80d0ceb] -> imap(io_loop_handler_run+0x69) [0x80d1509] -> imap(io_loop_run+0x28) [0x80d0bc8] -> imap(main+0x4cc) [0x8066c4c] -> dovecot: Dec 04 17:11:07 Error: IMAP(joewong99:joew.outblaze.com): /lib/libc.so.6(__libc_start_main+0xe0) [0x77df70] -> imap [0x8059571] dovecot: Dec 04 17:11:07 Error: child 32571 (imap) killed with signal 6 --
