[Dovecot] Split number of imap-login and pop3-login processes
by Mischa Peters 16 Aug '10

16 Aug '10

Hi All, Is there a way to define the number for imap-login processes and pop3-login processes separately? My mail server is getting more IMAP clients and much less POP3 clients these days and it continues to run out of authentication processes. I have been increasing login_max_processes_count the last couple of days and I noticed that it's split between IMAP and POP3. All 129 imap-login processes are tied up while there are only 3 of the 129 pop3-login processes in use. Any help would be greatly appreciated! Thanx!!

[Dovecot] Forcing users to change passwords

Suppose I have users with a default password like "change-my-password" and I want to detect users who haven't changed their password and alert (nag) them about changing it. How would I do that?

[Dovecot] Address book for 2.0?
by Jerrale G 16 Aug '10

16 Aug '10

2.0 could include a directory service, like MS Exchange, where people's address books within IMAP clients could be stored on the server and retrievable by the clients. Its a headache for users to roam from pc to pc and not have someone's address stored locally on another. Jerrale G SC Senior Admin

Could you provide a guess as to when it will be released so that I can plan downtime for the upgrade on my production servers? -- Dennis Clarke dclarke(a)opensolaris.ca <- Email related to the open source Solaris dclarke(a)blastwave.org <- Email related to open source for Solaris

Re: [Dovecot] turn Usernames in Lowercase
by Leander S. 15 Aug '10

Hi again, I solved the issue. Thanks any way and excuse the noise. http://wiki.dovecot.org/Variables Regards ________________________________________________________________________ Hi, I'm just curious how to force usernames to be modified to lowercase letters if one mixes uper and lower case letters to one salad? Cause my SpamAssassin gets confuesd and treats different spellings of Usernames as different Users - which is uncool. I've heard about something you can add in your dovecot.config to enforce lowercase letters only. Thanks

[Dovecot] Fatal: dict_driver_register(mysql): Already registered

All mail will sooner or later get delivered, using dovecot LDA from postfix, but these errors rampage the log several times. I recently added managesieve, expires, and finished the quota which I thought was achived by simply having quota_rule as a result of mysql.

With The dict {} and expire-related parts commented out, operation has no errors or delays; performance is exceptional with maildir, quota, sieve, and managesieve. I don't think managesieve would patch any part of the dictionary code as it only has to do with another service process, not a plugin; if the patching was to cause problems with other services, for the service definition coding, the other services would have a problem, correct? The expires dictionary mysql table was being correctly used, with one day of use, as there are 10000 records; I'm going to have to revise the mysql indexes for performance in case I am able to fix the dictionary problem. We like the 1.2.13 version of dovecot, as far as security, and wonder how I can find a correct defintion scripting for the dict {}, from a previous version, and merge. We are use to windows compilations. I am skeptical to go to dovecot 2.0 as our services are in production and 2.0 is beta. I have recompiled several times with fresh sources of dovecot 1.2.13, managesieve 0.11.11 patchl, and sieve 1.0.17 as directed by the Dovecot Wiki. Jerrale G, SCA

Is there a reference manual for changes in configuration between dovecot 1.2.X to 2.0 rc5. I know there is a config upgrade tool but I would rather learn the new changes and then implement them? -- Jerrale G. Jerrale G. SC Senior Admin

[Dovecot] v2.0.rc6 released
by Timo Sirainen 14 Aug '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc6.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc6.tar.gz.sig I expect this to be the last release candidate. Unless release critical bugs are reported, I'll update the version number to v2.0.0 on Monday morning without any other changes. Since rc5 there have been mainly some small fixes and some error message improvements. The only (somewhat) important fixes are: - dict quota didn't always decrease quota when messages were expunged - Shared INBOX wasn't always listed with FS layout
