[Dovecot] Funky quota things
by Guy 27 Jul '09

27 Jul '09

Hi guys, I already use Dovecot for imap/pop3 with some simple quota options. I'm starting to look at the switch from maildrop to dovecot lda and I'm wondering whether it's possible to do our unusual quota management with the quota plugin. We have the users total quota in MySQL along with a number of grace days (counts up to 7). The amount of space used is stored in maildirsize in the users maildir. What we currently some bits of voodoo which allow the user to go up to 200% of their quota. When they go over 100% they start receiving warnings and their grace days start counting down. If the account is still using over 100% of quota after the 7 days then the 100% quota is enforced so no new mail will be accepted. So is something like this "burst" quota possible in the Dovecot plugin? Thanks Guy -- Don't just do something...sit there!

Hello, we found dovecot down on one of our servers, with this error in the log: dovecot: 2009-07-14 04:05:04 Warning: SIGHUP received - reloading configuration dovecot: 2009-07-14 04:05:04 Error: Temporary failure in creating login processes, slowing down for now dovecot: 2009-07-14 04:05:04 Fatal: listen(143) failed: Interrupted system call we can reproduce this error with this tight loop: while date ; do kill -HUP $(cat /var/run/dovecot/master.pid) ; sleep 15s ; done after a while dovecot dies with the above error message. We are using # dovecot --version 1.0.15 in particular, Debian package with version "1:1.0.15-2.3" . This started since yesterday, when we upgraded to the latest Debian Lenny point release. The situation is rather problematic, and we'd like to here from you if there something we can do to fix it; if there's something you'd like us to do, just ask :) Thanks in advance, Sandro

[Dovecot] Sylpheed-claws and virtual mailboxes
by Thomas Berker 27 Jul '09

27 Jul '09

Hi! Has someone encountered the following problem? What am I doing wrong or does someone know a workaround? Dovecot 1.2.1 on Debian unstable, two namespaces: namespace private { prefix = location = maildir:~/res/Maildir:LAYOUT=fs inbox = yes list = yes } namespace private { prefix = gtd/ separator = / list = yes location = virtual:~/res/Maildir/gtd:LAYOUT=fs:INBOX=~/res/Maildir/gtd } The problem: cur, tmp, new maildir folders get created within the folder gtd when it is opened by Sylpheed-claws (3.7.1). Subfolders in gtd holding the dovecot-virtual files are not recognised as mail folders at all, they show up but do nothing. Other clients (I have tested thunderbird, evolution) work as expected: they show the folder gtd and the sub-folders perform searches. Thanks in advance, tb

[Dovecot] Problems with ioloop on MacOS
by David Abrahams 27 Jul '09

I've been using the macports version of dovecot, which is 1.1.11, on MacOS 10.5.6 $ /opt/local/sbin/dovecot --exec-mail imap Fatal: kevent(EV_ADD, 0) failed: Operation not supported This version is configured --with-ioloop=kqueue The problem seems to be known, if not understood: http://lists.apple.com/archives/Darwin-userlevel/2008/Dec/msg00010.html However, if I use --with-ioloop=poll, I eventually get IMAP(dave): [9079]: invalid I/O fd 0, callback 0x9330 (not from the above command; it's a little later when Gnus tries to interact with dovecot through the shell) I've been unable to build/install any later versions of dovecot on MacOS. autogen.sh fails like this: ... glibtoolize: putting auxiliary files in `.'. glibtoolize: copying file `./ltmain.sh' glibtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and glibtoolize: rerunning glibtoolize, to keep the correct libtool macros in-tree. glibtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. configure.in:281: installing `./config.guess' configure.in:282: required file `./config.rpath' not found configure.in:281: installing `./config.sub' configure.in:5: installing `./install-sh' configure.in:5: installing `./missing' src/auth/Makefile.am: installing `./depcomp' autoreconf: automake failed with exit status: 1 -- Dave Abrahams BoostPro Computing http://www.boostpro.com

[Dovecot] [BUG] Incorrect maildir quota value after maildirsize creation
by Adam Osuchowski 27 Jul '09

27 Jul '09

I found a problem with maildir++ quota. When dovecot creates maildirsize file, it counts quota wrong. This is, how I reproduce a situation on version 1.2.0: First, I remove maildirsize file: # cd /var/mail/test # rm -f maildirsize # ls -la total 32 drwx--S--- 5 mbox mbox 4096 Jul 12 20:45 . drwxrwsr-x 3 root mbox 4096 Jul 12 20:39 .. drwx--S--- 2 mbox mbox 4096 Jul 9 20:45 cur -rw------- 1 mbox mbox 491 Jul 12 20:45 dovecot-uidlist -rw------- 1 mbox mbox 8 Jul 12 20:45 dovecot-uidvalidity -rw------- 1 mbox mbox 8536 Jul 12 20:45 dovecot.index.cache -rw------- 1 mbox mbox 284 Jul 12 20:45 dovecot.index.log drwx--S--- 2 mbox mbox 4096 Jul 12 00:58 new drwx--S--- 2 mbox mbox 4096 Jul 12 00:58 tmp I have 8 emails which take 14183471 bytes together: # find cur new -type f | wc -l 8 # find cur new -type f -printf '%s\n' | awk 'END { print a } { a += $0 }' 14183471 Now, I connect to dovecot via POP3 and delete exactly _one_ email which takes 969 bytes. After that, maildirsize file has been created: # ls -la total 48 drwx--S--- 5 mbox mbox 4096 Jul 12 20:50 . drwxrwsr-x 3 root mbox 4096 Jul 12 20:39 .. drwx--S--- 2 mbox mbox 4096 Jul 12 20:50 cur -rw------- 1 mbox mbox 491 Jul 12 20:45 dovecot-uidlist -rw------- 1 mbox mbox 8 Jul 12 20:45 dovecot-uidvalidity -rw------- 1 mbox mbox 8536 Jul 12 20:50 dovecot.index.cache -rw------- 1 mbox mbox 532 Jul 12 20:50 dovecot.index.log -rw------- 1 mbox mbox 28 Jul 12 20:50 maildirsize drwx--S--- 2 mbox mbox 4096 Jul 9 00:58 new drwx--S--- 2 mbox mbox 4096 Jul 9 00:58 tmp # cat maildirsize 5242880S 14182502 7 -969 -1 So, maildirsize says, that there should be 7-1=6 emails which should take 14182502-969=14181533 bytes together. In fact, there are 7 emails (I delete only one of eight emails) which take 14182502 bytes together (deleted email taked 969 bytes): # find cur new -type f | wc -l 7 # find cur new -type f -printf '%s\n' | awk 'END { print a } { a += $0 }' 14182502 I figured, that dovecot after physically file removal, calls function maildir_quota_update(), which calls maildirquota_refresh() first (which in turn recalculate quota with new values), and then calls maildirsize_update(), which additionally and incorrectly decreases quota value.
