[Dovecot] Courier to dovecot migration issue
by Rami Rami 21 Oct '09

21 Oct '09

Hello, I am trying to migrate users form courier to dovecot 1.2.6. The main configuration parameters are as follows : ------------------------------------------------------------------------------------------------------ # 1.2.6: /usr/local/etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 2304).

This issue is resolved by replacing : maildir:~/Maildir:INDEX=/tmp/QUOTA/index/%u:CONTROL=/tmp/QUOTA/control/%u with maildir:~/Maildir any idea on the reason of these duplicates or workarounds to prevent them while keeping indexes in /tmp. Thank you.

[Dovecot] testing needed
by Timo Sirainen 21 Oct '09

21 Oct '09

Can someone find an OS where the attached program doesn't work? It should print "success". So far tested for success: Linux 2.6, Solaris 10, FreeBSD 7.2, OpenBSD 4.2.

Re: [Dovecot] IMAP goes down from time to time

Good afternoon again I was thinking about the Dovecot upgrading so i´m doing this in the next hours. in the other hand here i show you the dovecot-ldap.conf file I think it has just the necessary options to bind the LDAP server. /hosts = ********* base = ou=People,o=*****,o=****** ldap_version = 3 auth_bind = yes auth_bind_userdn = uid=%u,ou=People,o=******,o=****** /About the dovecot.conf should I use some login options as /login_process_per_connection = yes /or /login_processes_count = 1/? For now thanks so much for the help i´ll inform about the new version installation Juan Felipe Estrada dovecot-request(a)dovecot.org escribió: > Send dovecot mailing list submissions to > dovecot(a)dovecot.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://dovecot.org/cgi-bin/mailman/listinfo/dovecot > or, via email, send a message with subject or body 'help' to > dovecot-request(a)dovecot.org > > You can reach the person managing the list at > dovecot-owner(a)dovecot.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of dovecot digest..." > > > Today's Topics: > > 1.

[Dovecot] Question about IMAP IDLE (and Palm Pre)
by Ingo Thierack 20 Oct '09

20 Oct '09

Hello, i try to understand, how it works (IDLE). Try to get it successfully work with my new Palm Pre ;-) which looks like to have a lot issues wir imap... so i'll blame not dovecot for the issues. Sent a mail, from googlemail. processed by dovecot ad 12:11. what me now confusing, is, that there in the out-log is nothing visible, I expected, to see there was sent an notification, there was a new mail. Do i miss something? After arounde 15 minutes the Palm sent a "DONE" and reconnect. then the messages was received.

[Dovecot] Unknown setting: driver
by Rodolfo González González 20 Oct '09

20 Oct '09

Hi, the conversion from courier was done without problems, but now I have a problem with my auth config. I followed the sql example included in the latest dovecot source, and put driver=mysql in dovecot.conf (outside any section), and now I get: --- Error: Error in configuration file /usr/local/etc/dovecot.conf line 50: Unknown setting: driver Fatal: Invalid configuration in /usr/local/etc/dovecot.conf Starting DovecotError: Error in configuration file /usr/local/etc/dovecot.conf line 50: Unknown setting: driver Fatal: Invalid configuration in /usr/local/etc/dovecot.conf --- So I'm lost... what's wrong? if I followed the example :o Then, another question: I had to go back to courier so my users still can work, but I already created the files using the migration script: do I need to rerun the migration script? or what do I need to do when I manage to fix the error above and run dovecot? Thanks.

[Dovecot] clarify 'type', 'executable' & 'path' in 2.0 master.conf?
by PGNet Dev 19 Oct '09

19 Oct '09

@2.0's master.conf, there's, e.g., service config { type= config executable =config unix_listener { path = config mode = 0666 } } can someone please explain function/usage for the 'type', 'executable' & 'path' fields? and, for any file paths, are the presumed to be _relative_ to the dovecot executable? in $PATH? can they accept full/absolute paths? thanks.
