[Dovecot] v1.1.beta7 released
by Timo Sirainen 08 Nov '07

08 Nov '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta7.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta7.tar.gz.sig Changes since beta6: - Beginnings of unit tests, as I mentioned in a previous mail - Message parsing fixes - Cache file handling fixes Known bugs: - Cache file doesn't keep track of how much it contains deleted data, which means it could grow infinitely. This worked at some point, so I'm not sure what I did to break it. I'll figure it out later. - Apparently for some use cases v1.1 is still slower (about 2x) than v1.0. Probably more or less specific to NFS + mmap_disable=yes.

Unit testing is good, even though it's boring and not very glamorous. I wonder if you have seen or considered libtap, possibly as an optional dependency for those who care about running the tests? http://jc.ngo.org.uk/trac-bin/trac.cgi/wiki/LibTap It looks like it could almost drop in, in place of some of your existing test helpers. It is also compatible with a variety of end user test tools. However, I could see hesitation in adding external dependencies where they aren't really necessary. If you had TAP compatibility through libtap or other means, I could easily drop dovecot into our existing suite of nightly smoke tests on FreeBSD. > I'm probably going to be pretty lazy at adding more of those tests, so > if you've ever wanted to get your own code to Dovecot, now would be a > great time to do it! :) With a 5 month old and a 4 year old on hand, "copious free time" isn't my strong point, but I'll at least attempt to provide tests with any future bug reports. Thanks! Alan Ferrency

[Dovecot] How to set multi backends (with same type)
by maximatt 07 Nov '07

07 Nov '07

hi..... i don't know if its posible. i have two ldap directories, and i want use them to use as my dovecot users backend... so i have two configurations files... "dovecot-ldap1.conf" and " dovecot-ldap2.conf" and i try setting like: Test 1: (simil postfix ) :D This dont work auth default { : : passdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf, /etc/dovecot/etc/ldap/dovecot-ldap2.conf } userdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf, /etc/dovecot/etc/ldap/dovecot-ldap2.conf } } Test 2: This dont work auth default { : : passdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf/etc/dovecot/etc/ldap/dovecot- ldap2.conf } userdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf/etc/dovecot/etc/ldap/dovecot- ldap2.conf } } Test 3: (looking "passbd ldap" as a set) :) this work, but dovecot-ldap2.conf override dovecot-ldap1.conf (the set vision, none) auth default { : : passdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf args= /etc/dovecot/etc/ldap/dovecot-ldap2.conf } userdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf args= /etc/dovecot/etc/ldap/dovecot-ldap2.conf } } ¿How could i do this? :( Thanks in advance :) -- Salu2 ;)

[Dovecot] imaptest update
by Timo Sirainen 07 Nov '07

07 Nov '07

http://dovecot.org/tools/imaptest.c now keeps track of messages' metadata and complains if they change. It relies on Message-ID: header being unique in the source mailbox, otherwise it'll give bogus errors. I might fix that some day. I changed the code from using simple line-based parsing to Dovecot's imap-parser code. Unfortunately it looks like it's pretty slow. At least I'm pretty sure imaptest didn't take more than a few % of CPU before, while now it's showing 35% CPU usage.. I guess I'll have to profile it a bit to see what's eating the CPU. And yes, looks like it found a couple of bugs from Dovecot 1.1's MIME parsing (BODY/BODYSTRUCTURE replies change). That was actually why I wrote this code in the first place, I was trying to figure out how to reproduce a bug. I'm getting closer to my stress testing dream tool. :) http://mailman1.u.washington.edu/pipermail/imap-protocol/2007-March/000413.…

[Dovecot] Unit testing
by Timo Sirainen 07 Nov '07

07 Nov '07

I finally added beginnings of unit tests to Dovecot v1.1 code tree: http://hg.dovecot.org/dovecot/rev/4e4a5d6bb2cb There are currently just a couple of tests implemented in test-lib (lib/ functions) and test-mail (lib-mail/ functions). I'm probably going to be pretty lazy at adding more of those tests, so if you've ever wanted to get your own code to Dovecot, now would be a great time to do it! :)

[Dovecot] index corruption
by rosenfield＠users.sourceforge.net 07 Nov '07

07 Nov '07

Hi people Just switched to Dovecot yesterday, and I've already got about five reports of users with duplicate mail in their inbox :-/. Not as bad as lost email, mind you, but pretty annoying still. Checking the server log, it says: postfix/smtpd: disconnect from unknown deliver: msync() failed with index file maildir/dovecot.index: Input/output error unionfs: new lower inode mtime (bindex=0, name=maildir) dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error IMAP: Disconnected: Internal error occurred. Refer to server log for more information. This is dovecot version 1.0.3, the log presented here relates to only one user; user name snipped for anonymity purposes. Afterwards things just get worse and worse with the affected user: dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: Corrupted transaction log file maildir/.SPAM/dovecot.index.log: invalid new transaction log sequence (1 >= 1) dovecot: IMAP: fscking index file maildir/.SPAM/dovecot.index dovecot: IMAP: Transaction log file maildir/.SPAM/dovecot.index.log: marked corrupted dovecot: IMAP: Corrupted transaction log file maildir/.SPAM/dovecot.index.log: invalid new transaction log sequence (2 >= 2) dovecot: IMAP: fscking index file maildir/.SPAM/dovecot.index dovecot: IMAP: Corrupted transaction log file maildir/.Junk/dovecot.index.log: invalid new transaction log sequence (1 >= 1) dovecot: IMAP: fscking index file maildir/.Junk/dovecot.index dovecot: IMAP: Transaction log file maildir/.Junk/dovecot.index.log: marked corrupted dovecot: IMAP: Corrupted transaction log file maildir/.Junk/dovecot.index.log: invalid new transaction log sequence (2 >= 2) dovecot: IMAP: fscking index file maildir/.Junk/dovecot.index deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error What could be the problem? How do I go about debugging an issue such as this?

[Dovecot] IMAP - Empty attachments error
by Tomáš Klandra 06 Nov '07

06 Nov '07

Hallo, I have one problem with the following configuration: - server: debian, dovecot used as an IMAP server, version 0.99.14. - stations: windows 2k/XP, mailer seamonky 1.1.4 Sometimes (let's say once in 20 attemptes) when saving attachments, they are empty (zero size files). Simple re-saving them helps. I was looking on mozilla forums if it's not a bug in SeaMonkey, which looked more likely to me, but didn't find anything, so I got the idea it could be a bug in dovecot. If someone saw this as well or have any ideas, I would really appreciate any help about it, as the error is really annoying. Thank you, Tom

[Dovecot] User keywords limit to 26
by Arthur Pétry 06 Nov '07

06 Nov '07

Hi, I'm planning to use dovecot 1.0.5 for a webmail using a lot of user- defined tags. Recently, I just saw the limit of 26 of them when messages are stored in maildir format. This is an important issue for me, since I didn't find how to remove a flag from the dovecot-keywords database. Is there any plan to get rid of the keywords limit ? Or perhaps the new dbox storage format can fix that ? By the way, the comportement of Dovecot when we try to add a new flag while the limit is exceeded is strange : (C: is client and S: Dovecot) The store of the flags is ok : C: RUBY0094 UID STORE 89 +FLAGS (test_0 test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26) S: * 81 FETCH (UID 89 FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26 test_0)) S: RUBY0094 OK Store completed. And then when we fetch them, dovecot reply 2 times. The first time with all the flags, and the second time with only the 26 flags stored in maildir. (I suppose Dovecot try to sync the flags when we fetch it) : C: RUBY0095 UID FETCH 89 FLAGS S: * 81 FETCH (FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26 test_0) UID 89) S: * 81 FETCH (FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_0)) S: RUBY0095 OK Fetch completed.

[Dovecot] Sent vs Sent Items
by Ed W 06 Nov '07

06 Nov '07

Religious wars about which is "best" aside - some mail clients seem to default to using "Sent Items" folder for saving sent mail, and others (many) default to "Sent". Seems that in the interests of compatibility and "doing the right thing" (tm) that a symlink from one folder to the other name would ensure that either default would give the same result (in a mixed client setup)? However, I wonder if someone has already written a plugin to do something simple like this? More generally I guess it's folder aliasing, so that Sent == Sent Items and perhaps there are also synonyms for Drafts/Templates? Anyone got any thoughts on this simple idea? (The prob with sym links is a) creating them at mailbox setup time and b) what happens when someone tries to delete the folder...) Cheers Ed W
