[Dovecot] multiple connections per imap/pop3 process in 2.0
by Mike Abbott 12 Nov '09

12 Nov '09

When I set this in master.conf: service imap { service_count = 5 } I see this error when two imap users log in: Nov 11 16:54:16 server dovecot[5432]: imap-login: Login: user=<user1>, method=PLAIN, rip=10.100.0.84, lip=10.80.0.163, pid=5573 Nov 11 16:54:31 server dovecot[5432]: imap-login: Login: user=<user2>, method=PLAIN, rip=::1, lip=::1, secured, pid=5573 Nov 11 16:54:31 server dovecot[5432]: imap(pid 5573 user user2): Fatal: setgid(2002) failed with euid=2001(user1), gid=2001, egid=2001: Operation not permitted Then both users are logged out. Is there another setting I have to change to enable multiple connections per imap/pop3 process in dovecot-2.0, or does it just not work yet? I tried changing client_limit=5 but that had no effect. (I suggest that master.conf needs more documentation.) Thanks.

[Dovecot] Sluggish log process
by Pascal Volk 12 Nov '09

12 Nov '09

After the first `dovecot reload` the initial log process will not terminate immediately. The master logs: Nov 11 23:30:04 master: Warning: SIGHUP received - reloading configuration Nov 11 23:31:04 master: Warning: Processes aren't dying after reload, sending SIGTERM. Nov 11 23:32:04 master: Warning: Processes aren't dying after reload, sending SIGTERM. Nov 11 23:32:04 log: Warning: Killed with signal 15 (by pid=21639 uid=0 code=kill) With succeeding `dovecot reload`s the current log process terminates immediately Regards, Pascal -- The trapper recommends today: 5e1f1e55.0931602(a)localdomain.org

[Dovecot] patch for 2.0.alpha3 crash
by Mike Abbott 11 Nov '09

11 Nov '09

Dovecot-2.0.alpha3 crashes on startup for me on Mac OS X. It hits a segmentation fault at: 0 libdovecot.0.dylib 0x0000000100025e9f master_service_set_die_with_master + 10 1 libdovecot.0.dylib 0x0000000100025d93 master_service_settings_read + 1818 2 libdovecot.0.dylib 0x0000000100025e63 master_service_settings_read_simple + 110 3 dovecot 0x00000001000021d3 main + 846 4 dovecot 0x0000000100001650 start + 52 This appears to be because lib-master's master_service global (in the libdovecot shared library) is different from master's master_service global (in the dovecot binary). Here's a patch to fix it: --- a/src/master/main.c 2009-11-09 19:53:11.000000000 -0600 +++ b/src/master/main.c 2009-11-11 14:12:55.000000000 -0600 @@ -35,7 +35,6 @@ #define MASTER_PID_FILE_NAME "master.pid" #define SERVICE_TIME_MOVED_BACKWARDS_MAX_THROTTLE_SECS (60*3) -struct master_service *master_service; uid_t master_uid; gid_t master_gid; bool core_dumps_disabled;

[Dovecot] selective disable_plaintext_auth
by Mariano Absatz 11 Nov '09

11 Nov '09

Hi, I've been using dovecot for some time now, always with the setting: disable_plaintext_auth = yes so that no user can accidentally expose their username/password in the open. However, I'm now trying to configure a webmail client in a nearby server which doesn't support TLS or SSL IMAP connections :-( Is there any way to allow plaintext_auth only for a small set of IP addresses (for what I see in the comment, this is automatic for local addresses, alas, the webmail client is on another host).

Hi All, Sorry if this is a dumb questions, but what methods are available for retrieving mail for a system user i.e www-data. Basically my setup is just a normal Dovecot-IMAP which is working fine for shell users, but I want to be able to read mail for system users via IMAP. Is this doable? Cheers

[Dovecot] Multiple instances of dovecot in the same machine.
by Rodolfo Gonzalez Gonzalez 10 Nov '09

10 Nov '09

Hello all, I'm trying to run several instances of dovecot, with a different config each one, following the instructions from here: http://wiki.dovecot.org/RunningDovecot I try the command dovecot -c /etc/dovecot/installN/dovecot.conf and get: --- Error: ssl_cert_file: Can't use /etc/ssl/certs/dovecot.pem: No such file or directory Fatal: Invalid configuration in /etc/dovecot/installN --- but in my /etc/dovecot/installN/dovecot.conf file I have these lines: ssl_cert_file = /etc/dovecot/installN/ssl/certs/dovecot.pem ssl_key_file = /etc/dovecot/installN/ssl/private/dovecot.pem where both files exist and are valid. Any help is appreciated. Thanks, Rodolfo.
