by jan 18 Sep '05

Hi all, I use dovecot-1.0-alpha2. Way can't auth process shutdown in a clean way. I allways discover lot of zombies for dovecot-auth, in a short time before shootingdown by linux. But everything work fine for client side. Example: dovecot 22931 0.0 0.0 3840 1104 ? S 12:12 0:00 pop3-login dovecot 22932 0.0 0.0 3844 1108 ? S 12:12 0:00 pop3-login root 22933 0.0 0.0 0 0 ? Z 12:12 0:00 [dovecot-auth] <defunct> root 22935 0.0 0.0 0 0 ? Z 12:12 0:00 [dovecot-auth] <defunct> dovecot 22938 0.0 0.0 3848 1116 ? S 12:12 0:00 imap-login root 22975 0.0 0.0 0 0 ? Z 12:12 0:00 [dovecot-auth] <defunct> dovecot 22977 0.0 0.0 3844 1112 ? S 12:12 0:00 imap-login root 22978 0.0 0.0 0 0 ? Z 12:12 0:00 [dovecot-auth] <defunct> Best Reg. //Jan Holmberg

[Dovecot] Local authentication without password
by Sebastjan Trepca 18 Sep '05

18 Sep '05

Hi, is it possible to configure dovecot so that users from a specific IP (let's say 127.0.0.1) don't have to send password? They would be authenticated no matter if passwords match or not. Thanks, Sebastjan

[Dovecot] Error indexing mbox file (LF error)
by Kevin Old 18 Sep '05

18 Sep '05

Hello everyone, I'm getting the error below for 2 different users on my system of 150+ users: Sep 12 09:32:49 uavco pop3-login: Login: cah [::ffff:172.16.3.107] Sep 12 09:32:49 uavco pop3(cah): Error indexing mbox file /var/mail/cah: LF not found where expected Sep 12 09:32:49 uavco pop3(cah): Error indexing mbox file /var/mail/cah: LF not found where expected Sep 12 09:32:49 uavco pop3(cah): Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2005-09-12 09:32:49] I've read in the archives that it's the blank line at the beginning of the mbox file, and once deleted everything works fine. The thing is, it keeps happening and I can't figure out why. Email clients that send mail to these accounts are the latest Outlook Express. As I said, I have 150+ users on the same system and they are fine. I'm not sure if protocol makes a difference, but we are using POP3 only. Any ideas what I can do to fix/prevent/correct this either programatically or with a patch of some sort? Is this actively being worked on? I'm running FC4 with dovecot-0.99.14-4.fc4. Any help is appreciated! Kevin -- Kevin Old kevinold(a)gmail.com

[Dovecot] Dual INBOX Locations
by Calum Power 18 Sep '05

18 Sep '05

G'day list, Just a quick question - I need to configure Dovecot to do the following: * check default_mail_env for the users' inbox in MBOX format * If the above fails, serve the user an inbox from a secondary location, in MAILDIR format. I have read up on Namespaces, however I can't seem to get this to work - login just fails when Dovecot cannot find the inbox in default_mail_env Any advice, anyone? :) Thanks, Calum -- Calum Power Systems Administrator Server101 Pty.

[Dovecot] problems with Auth and Alpha 1a
by Søren Peter Skou 18 Sep '05

18 Sep '05

Hi all I'm not quite sure how to explain this problem, so I'll just go from the top ;-). System is setup on a FreeBSD with IMAP and POP3, both can use PAM and SQL (MySQL) as login methods, though only POP3 is accessible from "the world" - IMAP is restricted via firewall to only localhost. Simple eh? The problem is that dovecot apparently drops the SQL part from time to time. Though this can be fixed by HUPing the dovecotdaemon I'd rather that I didn't have to. I've narrowed the problem to something like this: Over time, Dovecot/POP3/SQL combination dies - I've yet to examine if the problem is on IMAP as well as this is only recently reported. I have never experienced this myself since I'm using Dovecot/IMAP/PAM and this seems to be rock solid. The configuration looks like this: OS: FreeBSD n/a 6.0-BETA3 FreeBSD 6.0-BETA3 #0: MySQL: 5.0.9-beta-log Dovecot: alpha 1 (I'll test Alpha 2 to see if the problem persists) Compilation options for dovecot: ./configure \ --enable-ipv6=no \ --with-ldap=no \ --with-vpopmail=no \ --with-mysql \ --with-ssl=no dovecot.conf: base_dir = /var/run/dovecot/ protocols = imap pop3 ssl_disable = yes disable_plaintext_auth = no login_user = dovecot login_process_per_connection = no login_greeting = Ready max_mail_processes = 1024 first_valid_uid = 1 first_valid_gid = 1 protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } passdb sql { args = /usr/local/etc/dovecot/mysql.conf } userdb sql { args = /usr/local/etc/dovecot/mysql.conf } user = root } -- END -- sql.conf: driver = mysql connect = host=localhost port=3306 dbname=N/A user=N/A password=N/A client_flags=0 default_pass_scheme = CRYPT password_query = SELECT password FROM mail WHERE username = '%n' and domain= '%d' user_query = SELECT concat('/VIRTUAL_MAIL/',domain,'/',username,'/') as home,concat('/VIRTUAL_MAIL/',domain,'/',username,'/') as mail, 1 as uid, 6 as gid FROM mail WHERE username = '%n' and domain = '%d' -- END -- I'm sort of at a loss here since everything "seems to be working" (tm) for one part, but not another Hope someone has an idea ;-) Søren P.

[Dovecot] what does this mean: Warning: Error in custom flags file / Corrupted Indexes
by rick tait 18 Sep '05

18 Sep '05

Hi everyone: I am seeing a whole LOT of these messages in my dovecot logfile: imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 0 imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 1 and also these: imap(mbwnews): Sep 12 17:10:16 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) imap(mbwnews): Sep 12 17:10:18 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) And not just referring to my inbox, other users as well. I hava bog standard install of 0.99.10.8, on an openbsd 3.6 box. every now and then i get an error from my or my users' IMAP email client saying that it couldn't access a particular inbox. a few clicks of "OK" or "Cancel" etc and the problem seems to go away. all kinds of errors (similar to above) in the imapd logfile though, seem to correspond with the timing of the abovementioned IMAP mail client errors. one thing: my users DO use procmail, so there is a chance that their IMAP client might have a mailbox open that procmail may be trying to append to. i wonder if this is a locking issue? i guess what i'm asking is - 2 thing: 1) how can i get these pesky imap client errors to go away so my users mailboxes can be successfully selected? 2) what do the indexing errors mean? are the 2 things related? Thanks so very much in advance everyone! Best, Rick. rick tait | e: rickt(a)rickt.org | t: 323.829.5703

[Dovecot] Timeout while waiting for lock....
by Rob Frohne 16 Sep '05

16 Sep '05

Hi, I'm very new to administering mail, and this is surely a newbie question. I have my own IMAP mail server because I use my email as a way of filing important things, and I subscribe to a number of lists that I like to archive. I have about 40 mailboxes with up to 80,000 messages in some, and one with 40,000 messages is almost a Gigabyte in size. The total size is around 4 Gigabytes. Things were working quite well until I upgraded to OS X 10.4 and its new Mail.app mail client and then everything was too slow. I was using the UW IMAP server (2002d if I recall right) and Mail.app 1.3.9. I tried upgrading the server to the latest, but it didn't improve things noticeably. I swapped to dovecot 1.0alpha1, and used the mbox format, but that wasn't any better. I read that Maildir format was better, so I converted my mail to that format and tried that. It didn't seem much better. I tried to compile Cyrus on OS X and ran into all kinds of difficulty. I finally tried Cyrus on a Linux box, and turned off all my rules that move messages around. In comparing this to dovecot on my OS X box, Cyrus loads the messages significantly faster. I think there are some problems with my dovecot setup though. My mail.log is filled with this type of thing. Sep 15 16:43:51 cubex-wwc-edu dovecot: imap-login: Login: user=<frohro>, method=PLAIN, rip=172.17.128.191, lip=10.7.3.11 Sep 15 16:44:43 cubex-wwc-edu dovecot: imap(frohro): Timeout while waiting for lock for transaction log file /Users/frohro/Maildir/dovecot.index.log Sep 15 16:44:57 cubex-wwc-edu dovecot: imap-login: Login: user=<frohro>, method=PLAIN, rip=172.17.128.191, lip=10.7.3.11 Sep 15 16:45:51 cubex-wwc-edu dovecot: imap(frohro): Timeout while waiting for lock for transaction log file /Users/frohro/Maildir/dovecot.index.log I've tried mutt, evolution, kmail, and am now using Thunderbird, and am working on getting Mail.app to import an archive of my 4 Gigs of mail, thinking if nothing else works, I can have a copy of that on the clients I use, though I like having it on the server better. Can anyone suggest something to fix my problems, besides deleting all my email? Thanks, Rob

[Dovecot] SSL/TLS stopped working in 1.0 alpha2
by Andy Cravens 15 Sep '05

15 Sep '05

I have both 1.0 alpha1 and alpha2 installed on my test mail server. SSL/TLS does not work on alpha2. I'm using the same config file for both. No errrors in dovecot.log either. Is there a way to increase debugging info without recompiling?
