[Dovecot] Run fetchmail after login?
by Brett B. 20 Feb '07

20 Feb '07

Hello all, I was wondering if it is possible to run fetchmail after a user logs into dovecot? So far I have tried to make a small script that contains the command for fetchmail. Then I told the dovecot mail_executable to look at that script. However this ends up leaving the server hanging and does not seem to work. Thanks

[Dovecot] Dovecot losing .mailboxlist files
by Lauri Jesmin 20 Feb '07

20 Feb '07

Hello! I am running a site that has two servers, 10 000 users in both, Solaris 9 and home directories with mbox mailboxes shared with NFS. Indexes are kept separately in both server, on local disks, both servers are serving imap (from NFS mboxes). We are trying to convert from uw-imap to dovecot. Servers are currently running on their limits and now i have mysterious problems with .mailboxlist file: i patched dovecot to use .mailboxlist file instead of .subscriptions, but sometimes the .mailboxlist file disappears on some users. Instead there are appearing .nfsXXXXXX files, where XXXXXX is combination of numbers and capital letters. Also some users have problems with subscribing to folders, others do not have this problem. It seems to be that users who do not have .mailboxlist have also problems with subscribing to folders. Dovecot is version 1.0rc22. I have not discovered error messages in logs. -- Lauri Jesmin <lauri.jesmin(a)ut.ee> Tartu Ülikool

[Dovecot] Weird Issues with latest nightly (pre-rc23)
by Cassidy B. Larson 20 Feb '07

20 Feb '07

Just updated one of my proxy boxes to the latest nightly (20070217), restarted the dovecot process and got a bit of errors showing up for each pop3/imap connection. Feb 19 11:14:00 marbella dovecot: pop3-login: Login: user=<user1(a)host.com>, method=PLAIN, rip=209.33.217.218, lip=204.17.177.60 Feb 19 11:14:00 marbella dovecot: POP3(user1(a)host.com): Set pop3_uidl_format in config file Feb 19 11:14:00 marbella dovecot: child 33684 (pop3) returned error 89 Feb 19 11:14:04 marbella dovecot: imap-login: Login: user=<user2(a)host.com>, method=PLAIN, rip=204.17.177.50, lip=204.17.177.60 Feb 19 11:14:04 marbella dovecot: IMAP(user2(a)host.com): mbox: Can't create root mail directory /dev/null/mail: Not a directory Feb 19 11:14:04 marbella dovecot: IMAP(user2(a)host.com): MAIL environment missing and autodetection failed (home /dev/null) Feb 19 11:14:04 marbella dovecot: child 33753 (imap) returned error 89 On the pop3 errors above. Why should I have a pop3_uidl_format in the config file for the proxy? This was working fine on rc19. I do have a pop3_uidl_format on my storage boxes. Same with the imap section. It should just proxy over (and is on rc19), the proxy shouldnt have to know about the mail directory. Am I the only one seeing this? Or have I missed a config change that is required? thanks, Cassidy

[Dovecot] Dovecot authentication problem
by Marion Keith 20 Feb '07

20 Feb '07

Hi all, New SUSE 10.2 install, Sendmail, dovecot 1.0.rc14-7 SUSE rpm. Was using PAM for authentication. Worked like a champ since Feb 7th. No changes to system. Yesterday authentication failed. I can't even authenticate locally with "telnet localhost" options to test pop3 or imap. It appears that my pam authentication has somehow gotten changed. Can anyone direct me to some PAM debugging help? Thanks, Marion

[Dovecot] LDAP auth load? (looking for advice)
by Troy Engel 19 Feb '07

19 Feb '07

One of the changes my beta testers are testing is switching from NIS to LDAP for login/auth/homedir lookups; all is working perfectly, Dovecot + PAM/nss_ldap is A-OK. No issues here, we've been using LDAP lookups on other servers for years. I'm wondering about load, specifically if when I switch the entire company over, will the new authentication load stress my LDAP server to the point of breaking. A) Does anyone here have some numbers or experience in this switch that could lend some real-world advice? We're talking maybe... 50 people with large (numerically, not gig-age) mailboxes, and ThunderBird seems to open 4-5 connections per client based on the logs. B) Would anyone advise that I run a slapd slave directly on the main Dovecot server to alleviate load? Is this overkill and I shouldn't worry about it? Mainly what has me concerned is that on the Dovecot machine, I'm getting a number of entries in the messages that look like: dovecot-auth: nss_ldap: reconnecting to LDAP server... dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) No failures ever, it all just works. But still this tickles my brain that maybe it'll need more robustness come production time. Thanks for your feedback, -te -- Troy Engel | Systems Engineer Fluid Inc. | http://www.fluid.com

[Dovecot] repeat downloads of message headers in 1.0rc19
by Brian G. Peterson 19 Feb '07

19 Feb '07

I upgraded one server to 1.0rc19 (from rc15) over the weekend, and have since received several reports of dovecot erroneously retrieving older messages as new mail. I've seen this myself intermittently on KMail, and users have reported it on Thunderbird, Squirrelmail, and Outlook. I see some things in the archives that suggest that this was a problem in older 1.0 release candidates, but hadn't experienced the problem myself until just now. Has anyone else seen this problem? Regards, - Brian

[Dovecot] wrong dovecot GID while upgrading
by Zbigniew Szalbot 18 Feb '07

18 Feb '07

Hello, I tried to upgrade dovecot from 1.0.rc7 to rc22 but I got this error at the end of the upgrade process: Dovecot has reserved the groupname 'dovecot' and gid '143': ERROR: groupname 'dovecot' already in use by gid '1003' Please resolve these issues and try again: Either remove the conflicting group or if you wish to continue using a legacy gr oup override DOVECOT_GID. *** Error code 1 Stop in /usr/ports/mail/dovecot. So I went to /usr/ports/mail/dovecot and edited the Makefile to change the GID into: DOVECOT_UID?= 1003 DOVECOT_GID?= 1003 SCRIPT_ENV+= DOVECOT_UID=${DOVECOT_UID} \ DOVECOT_GID=${DOVECOT_GID} I saved the makefile and ran portupgrade again but I got stopped by exactly the same error. I'd appreciate suggestions how to resolve this. Thank you! -- Zbigniew Szalbot

[Dovecot] Reproducible duplicate messages bug with Mail.app+Dovecot
by Andrew Moran 18 Feb '07

18 Feb '07

Hey guys, I am not sure if this is a Mail.app bug or a dovecot bug. I can reproduce it 100% of the time using dovecot and Mail.app. I cannot reproduce it with other imap clients, which at first made me think it was Mail.app, but then I tried Mail.app with other imap servers and couldn't reproduce it either, so it's definitely the combination of the two. So I thought I'd try you guys first before submitting a bug to Apple. The problem: If I move multiple messages (set "A") from one imap folder to another, then delete those messages, and then move another set into that same folder (set "B"), then all the messages in set B show up as duplicates until I relaunch Mail.app. My configuration: Server: Dovecot 1.0rc22 using Maildir on FreeBSD 6.1 Client: Mail.app 2.1 on OS X 10.4.8 Steps to reproduce: (these steps involve trashing messages, so it's best to test this on email you are going to toss anyway) 1) Create a new imap folder (let's say "bar") 2) Drag more than one message (let's say 3 or 4) from existing imap folder "foo" to new folder "bar". 3) Click on new folder "bar" and see messages in there. 4) Select messages and delete them (Delete key). Messages are gone as expected. 5) Go back to original folder "foo" and drag a few more messages into new folder "bar" 6) Click on bar. 7) You will notice that all the second set of messages show up twice. Relaunching Mail.app at this point makes the problem disappear. I'm guessing this has something to do with the deleted messages from Set A being purged until the close of imap connection. Any help narrowing this down would be appreciated. Thank you, --Andy

[Dovecot] Problem moving emails with attachments or HTML links
by J. Wren Hunt 18 Feb '07

18 Feb '07

I recently switched from UW-IMAP to Dovecot (1.0.rc15 on Ubuntu) and am experiencing a weird problem that I haven't been able to figure out yet: If I try to move a message from one IMAP folder to another, all works fine if the message is plain text. However, *sometimes* the message will not be transferred if it contains either an attachment and/or an HTML link (operation times-out). Not all the time, but just enough to be annoying. I've looked through the logs and for settings in the .conf file and can't find anything obvious that I've overlooked. Can anyone help me with any parameters that might be causing this type of problem? Thanks so much! Wren Hunt Cambridge, MA
