[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.

Here is the relevant config: dovecot-mysql query: user_query = SELECT CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/') AS home, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/sieve/', mailboxes.username, '.sieve') as sieve, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/sieve/') as sieve_dir, CONCAT('/home/mail/', mailboxes.domain, '/', mailboxes.username, '/mail/') AS maildir, uid AS uid, gid AS gid, CONCAT('maildir:storage=', ROUND(mailboxes.quota/1200), 'M') AS quota_rule, 'Trash:ignore' AS quota_rule2 FROM mail.mailboxes WHERE username = '%n' AND domain = '%d' AND active = '1' dovecot.conf: protocol managesieve { listen = localhost:2001 managesieve_implementation_string = dovecot managesieve_logout_format = bytes ( in=%i : out=%o ) mail_executable = /usr/libexec/dovecot/managesieve login_executable = /usr/libexec/dovecot/managesieve-login } auth_debug = no auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/dovecot-mysql.conf # scheme = cram-md5 } userdb sql { args = /etc/dovecot/dovecot-mysql.conf } user = mail socket listen { client { path = /var/spool/postfix/private/auth user = postfix group = postfix mode = 0660 } master { path = /var/run/dovecot/auth-master mode = 0666 } } } dict { # # NOTE: dict process currently runs as root, so this file will be owned as root. expire = mysql:/etc/dovecot/dict-expire.conf quotadict = mysql:/etc/dovecot/dict-quota.conf } plugin { quota = dict:user::proxy::quotadict expire = Trash 7 Trash/* 7 Spam 30 expire_dict = proxy::expire expire_altmove = * 2555 sieve_global_path = /home/mail/sieve/global.sieve sieve_global_dir = /home/mail/sieve sieve_dir=/home/mail/%d/%n/sieve } As said, everything works, eventually, but mail delivery is delayed a lot. 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

[Dovecot] Dovecot Upgrade Manual for 2.0 from 1.2.14 snapshot
by Jerrale G 15 Aug '10

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

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

I added some new filters to this list that will bounce your mail if it doesn't like it. If you think your bounced mail was legitimate, let me know and I'll look at fixing the scripts.

[Dovecot] Maildir over NFS
by CJ Keist 14 Aug '10

14 Aug '10

I'm working on bring up a new mail server to replace our current one. Our current mail server is running dovecot 1.1.16, with postfix using mbox format. User inboxes are stored locally on the mail server and all other mail folders in users home directory under mail which is NFS mounted on the mail server. For our new mail server I'm looking to switch to the Maildir format. Some years ago I remember reading that it was not recommended to run Maildir format over NFS. Now I'm looking at several posts that seem to indicate that Maildir should run fine over NFS. I'm a little concerned about running Maildir over NFS, especially from the howto conversion pages I read would move all messages over to the User ~/Maildir folder including the inbox. So having every single mail transaction going over NFS doesn't seem the smart thing to do. So question I have for the dovecot team, does running Maildir over NFS work well? Or would you recommend that all user mail folders be stored locally on the mail server when using Maildir? We have about 3400 users, doing about 30k mail deliveries daily. Some users have 10's of thousands of mail messages in hundreds of mail folders. Thanks... -- C. J.
