[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.

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?

This is not an evidence, but a strong doubt: the same problem is still present after replacing MailScanner by amavisd-new. It could be that it happens less often, although, but I need some time to make real stats... -- ---------------------------------------------------------------------- Yannick Majoros http://www.inma.ucl.ac.be/~majoros Informaticien AUTO-INMA/FSA/UCL CSAM 4, avenue G.

[Dovecot] Dovecot-LDA problems (CVS version) Signal 11 and empty 'mail' dir
by Steffen Kaiser 14 Sep '05

14 Sep '05

Hello, I'm trying dovecot-lda (deliver.c has CVS version 1.18). When I try to deliver a mail, an empty directory is created name $HOME/mail. This is neither the configured (via LDAP) nor the default "mail" setting in the /usr/local/etc/dovecot-deliver.conf. When the $HOME directory does not exist, but the user itself: Sep 1 11:47:12 localhost deliver: mbox: Can't create root IMAP folder /home/skaise2a/mail: Permission denied Sep 1 11:47:13 localhost sm-mta[4684]: j819lCgd004682: SYSERR(root): mailer local died with signal 11 Default mail: mail = maildir:%h/.mailboxes:INDEX=/usr/local/var/spool/dovecot/indexes/%Lu Configured via LDAP for user skaise2a: maildir:/mailcache/skaise2a:INDEX=/var/cache/dovecot/indexes/skaise2a:CONTROL=/var/cache/dovecot/control/skaise2a I have only found the error message in dovecot's src/lib-storage/index/mbox/mbox-storage.c function create_root_dir(). The Dovecot logs indicate that dovecot-lda is requesting the information from it and the message is - once the empty directory could be created - delivered into the configured IMAP root.

Locking _does_ work for postfix and dovecot (discussed with Wietse, partly by mail). Any idea? As an alternative, is there a way of handling the problem better? Dovecot just locks on these corrupt mailboxes :-/ I didn't try Dovecot 1.0, as it is alpha and I don't have any package for that anyway (production system :-/ ).

[Dovecot] Solaris build failed
by GARY GENDEL 14 Sep '05

14 Sep '05

dovecot-v1.0-alpha build failed for Solaris 11 (OpenSolaris Nevada). The problematic line is in socket.c line 228. The fix should be to change SOL_TCP to IPPROTO_TCP found in netinet/in.h. This change should work universally on all platforms. Gary

[Dovecot] what does this mean: Warning: Error in custom flags file / Corrupted Indexes
by rick tait 13 Sep '05

13 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
