[Dovecot] Auth wit multiple ldap configfiles
by Dominik Saar 18 Jan '06

18 Jan '06

Hi, trying to deliver local mails with exim over dovecot. The problem is, that i logged in with a username from ldap to imap For this i created in dovecot.conf auth imap { args = /path/to/dovecot-ldap.conf ...... } And for delivery i use command = /path/to/dovecot/deliver -d $local_part@$domain in the exim.conf $local_part is diferent to the loginname in the ldaptree So i create in dovecot.conf auth deliver { args = /path/to/dovecot-ldap_deliver.conf } Sometime dovecot check the "auth deliver" section and sometimes the "auth imap" section i created. I don´t understand why dovecot doesn´t check allways both sections?!? P.S.: Sorry my english :)

[Dovecot] gdbhelper.c concerns
by Jeff A. Earickson 17 Jan '06

17 Jan '06

Timo, I was surprised to find both an execvp() and a system() call in gdbhelper.c. While gdbhelper should be running as an ordinary user (the person running imap), I find it a bit scary. I realize that the code is getting ready to run gdb, which is god-knows-where in the user's path. But still... Maybe the code should do a getuid() and/or geteuid() and refuse to run if the uid is zero. Also, the code does the fork() *before* checking the argc count. Maybe do it the other way around so the i_fatal is killing one process instead of two. Jeff Earickson Colby College

[Dovecot] 1.0beta1: bullet-proofing dovecot-example.conf
by Jeff A. Earickson 17 Jan '06

17 Jan '06

Timo, I got bit last night during my upgrade to beta1 by uncommenting the following part of dovecot.conf for my site: #passdb passwd-file { # File contains a list of usernames, one per line #args = /etc/dovecot.deny #deny = yes #} I did a "s/#//" over this block of code, thereby uncommenting the comment too. Then I wondered why beta1 wouldn't start for me, until I found the conf syntax error. I suggest "bullet-proofing" some of the comments in dovecot-example.conf against this error, like so: #passdb passwd-file { ### File contains a list of usernames, one per line #args = /etc/dovecot.deny #deny = yes #} Attached is a diff against beta1 dovecot-example.conf to fix this kind of dumb mistake.

[Dovecot] SSL and login_process_per_connection = no
by Chris Wakelin 17 Jan '06

17 Jan '06

Just thought I'd check, but is the combination of SSL and "login_process_per_connection = no" expected? I'm wondering, because imap_login is doing the SSL-proxying, and in our live Dovecot instance we have "login_process_per_connection = no" (we had problems with authentication and running out of file descriptors early on, now fixed by using userdb = passwd-file rather than NIS). This combination seems to work OK in 1.0-beta1, except I just got disconnected with a log entry: Warning: imap-login: SSL_write() syscall failed: Bad file number [<IP address>] which I've never seen before (though I've been testing this with alpha5 for weeks).

[Dovecot] Duplicate suppression
by Greg Trounson 17 Jan '06

17 Jan '06

Hi there, Does the Dovecot project have plans to implement duplicate suppression at some stage? I have a situation where several people belong to more than one mailing list. One alias ('staff') incorporates several lists. These staff are receiving duplicate messages (one copy for every list they're on) when a message is sent to this staff alias. There is no reason they need to receive more than one copy. There seems to be no way I can turn that feature off in my MTA so I thought I'd try a bit further down the chain. thanks, Greg
