[Dovecot] List problems?
by Charles Marcus 16 May '07

16 May '07

Hi Timo, Sorry to bother you, but I'm used to having at least 10-20 in the morning. This morning there are none... and the last one is from 3:00pm yesterday? So, this is a test, I guess... -- Best regards, Charles

[Dovecot] Deliver sending bounces from 'MAILER-DAEMON@'
by Erland Nylend 16 May '07

16 May '07

Hello, I'm having a problem with postfix and/or dovecots "deliver". I'm getting these lines in the mail log: | Apr 24 11:42:08 smtp2 postfix/qmgr[6176]: 05BAE3B67E: from=<>, size=3055, nrcpt=1 (queue active) | Apr 24 11:42:08 smtp2 postfix/qmgr[6176]: 05BAE3B67E: to=<MAILER-DAEMON@>, relay=none, delay=0.01, delays=0.01/0.01/0/0, dsn=5.1.3, status=bounced (bad address syntax) After some debugging, it seems that those lines in the log appear if I send mail to an account which is over quota. (I'm using the Maildir++ quota) This is from my dovecot.conf: | protocol lda { | postmaster_address = MAILER-DAEMON(a)my.domain.tld | mail_plugins = quota | auth_socket_path = /var/run/dovecot/auth-master | hostname = my.mail.server | sendmail_path = /usr/sbin/sendmail | } It seems to me that dovecot is sending bounce messages from 'MAILER-DAEMON@' .. Does anyone know why this is happening, or how I can specify the address to be used? I'm using dovecot 1.0.0. -- Erland Nylend

[Dovecot] Thunderbird or Dovecot bug? (multiple keywords)
by Troy Engel 15 May '07

15 May '07

Here's a strange one. I have a user who's using Thunderbird 2.0.0 and assigning multiple tags (keywords) to emails, which are getting "lost" (I'll explain) when he leaves the folder and comes back. I can reproduce this on *his* account myself, but cannot reproduce it on *my* account (separate new TBird 2.0.0 profiles on Windows XP). Use the two TBird default tags 'Important' and 'Work' for all these tests, which it refers to as $Label1 and $Label2 in IMAP-keywords land. If I go into my account, label an email with both tags, it sticks -- I can click on Drafts then back to Inbox, and both tags/keywords still show in the client. If I go into his account, add the two tags, then click on Drafts and back on Inbox, only the *second* tag (Work, $Label2) shows. If I remove that tag, then the first tag (Important, $Label1) immediately pops up! On the backend the actual Maildir files match the dovecot-keywords and have the correct letter appended in both cases - so, in his account when the email only shows one tag, the physical mail file has the letters for two tags. So Thunderbird should be showing both tags, like it does in my account where everything is working correctly. This leads me to believe that the problem has something to do with the difference of dovecot-keywords content, and the interaction TBird has with Dovecot. My account, working correctly, looks like: dovecot-keywords: 0 $Forwarded 1 $MDNSent 2 $Label2 3 $Label1 file: Maildir/cur/1178712608.H529732P11686.yak.fluid.com:2,RSdc ...which matches, d=$Label1 (Important), c=$Label2 (Work) and TBird is displaying the email as having both tags - all is well and good. Now, his account looks like: dovecot-keywords: 0 Junk 1 NonJunk 2 $Label4 3 $Label1 4 $Label2 5 $Label3 6 $Label5 file: Maildir/cur/1178728930.P28392Q0M960111.yak.fluid.com:2,RSbde ...again, everything matches on the server; yet, it Thunderbird is only displaying $Label2 (d,3). I also noticed something interesting, even if I have the TB 'Junk Controls' completely disabled on his account, and remove all tags using the menu option, that file still retains the 'b' (NonJunk) tag in the filename: Maildir/cur/1178728930.P28392Q0M960111.yak.fluid.com:2,RSb All this long-winded explanation leads me to believe that somehow the difference in dovecot-keywords is causing this problem, but what I can't tell is who's problem it is -- Dovecot, or Thunderbird? Thoughts welcome, -te PS: all the normal things tried like deleting the dovecot index files, Thunderbird cache files and profiles, etc. -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] Why is direct invocation of dovecot preferred over inet inclusion?
by Stewart Dean 15 May '07

15 May '07

I'm used to putting things in inetd and, 1) should dovecot crash, I'd think it would get restarted if it was invoked from inet's imap-login 2) it would get started well after the boot ...wouldn't that be preferable.

[Dovecot] Question: contention with blackberry
by Stewart Dean 15 May '07

15 May '07

My production imap is currently UWIMAP with mbox.. One of the problems commonly observed is mailbox lock loss, which happens when: a) a VIP has multiple secretaries accessing a single mailbox (actually, they are professional enough to have figured the realities of conflicting access and rarely have a problem), b) somebody leaving their machine on at home and coming in and firing up their work computer c) important people with Blackberries....and the BB service polls the mailbox every so often and breaks the lock. In any case, the maillog ends up with a message like this: > May 5 19:45:04 mercury mail:info imapd[2035774]: Logout user=xxxxx host=bda056.bis.na.blackberry.com [216.9.249.56] > May 5 19:46:52 mercury mail:info imapd[2502902]: Killed (lost mailbox lock) user=xxxxx host=cpe-24-161-103-11.hvc.res.rr.com [24.161.103.11] How will this work with Dovecot? I regard what is happening now as OK, working as designed. Although we may eventually move to a different mailbox format, I am only switching from UW to DC in the first step. -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035
