[dovecot] dovecot.spec

hi, I'm just recoginze that dovecot contains an rpm spec file. unfortunately it's not too useful since an rpm -ta dovecot-.x.y.tar.gz can't be used since just the dovecot.spec.in is in the tarbar and not the actual spec file (which is in this from not useful in the above form). anyway here is my patch to the spec.in. -- Levente "Si vis pacem para bellum!" --- dovecot/dovecot.spec.in.lfarkas 2003-05-05 16:36:16.000000000 +0200 +++ dovecot/dovecot.spec.in 2003-05-05 17:04:30.000000000 +0200 @@ -1,9 +1,11 @@ # DarContact: Timo Sirainen <tss(a)iki.fi> +%define uid 96 +%define gid 96 Summary: Dovecot secure IMAP server.

[dovecot] KMail?
by Joakim Ryden 07 May '03

07 May '03

Hey everyone - is anyone else having problems with Dovecot and KMail? I'm having trouble seeing my INBOX using KMail (Maildir format on the server), though all subfolders show up as normal. I suspect the problem is with KMail as all the other mail clients I've tested seem to have no such problems, they see INBOX *and* subfolders just fine, just wanted to see if anyone could confirm this behaviour? --Jo

[dovecot] dovecot and squirrelmail
by Warren Togami 07 May '03

07 May '03

Is anyone using squirrelmail with dovecot? After a few minor tweaks squirrelmail seems to work great, but I can't seem to get rid of the "./" folder. SquirrelMail implements some workaround hacks for specific IMAP server quirks. The default setting is: $imap_server_type = 'uw'; What settings do you folks use?

[dovecot] 0.99.9.1 - Runaway imap-login process

When I attempt to strace -p this runaway process, it strangely displays nothing. kill was able to get rid of it. After I added an appropriate /etc/pam.d/imap entry, auth works and I didn't see this runaway process. This is a RH9 chroot server instance running within Linux virtual server with security contexts kernel. (Think of it as a theoretically unbreakable chroot.) Any tips on what I can do to get some debugging information out of this? Thanks, Warren Togami warren(a)togami.com

[dovecot] 0.99.9.1
by Timo Sirainen 05 May '03

05 May '03

Some bugfixes: v0.99.9.1 2003-05-03 Timo Sirainen <tss(a)iki.fi> - Messages having lines longer than 8192 bytes caused problems. - There was some problems when opening a mbox first time that had been empty for a while. - Didn't compile with OpenBSD. - POP3 server crashed sometimes instead of printing error message. - If cached IMAP envelope contained literals, SEARCHing in it wrote errors to log file. For example if subject contained highascii, '"' or '\' characters this happened.

As promised yesterday :) BTW. I just found libsqlora8 library yesterday and I've been playing with Oracle mail storage support. Shouldn't take too long to get it working. And the NEWS file once more: v0.99.9 2003-04-28 Timo Sirainen <tss(a)iki.fi> * WARNING: mbox rewriting works now faster, but it's less likely to notice external message flag changes (it wasn't perfect before either). This also means that if you're not using index files, Dovecot may not notice changes made by another Dovecot process. This will be fixed later. + Message UIDs are now permanently stored outside index files. Deleting indexes is now possible without any kind of data loss and in-memory indexes are now usable. + mbox rewriting leaves extra space into X-Keywords header. It's shrinked or grown when updating message flag headers to avoid rewriting the rest of the file. + imap-login and pop3-login can now be started from inetd. Privilege separation is still used, so it executes dovecot and dovecot-auth processes which are left on the background. + PostgreSQL authentication support, patch by Alex Howansky - Large multiline headers (over 8kB) broke Dovecot before. Now they're parsed one line at a time and we try to avoid reading them fully into memory. - SEARCH OR was broken - Partial BODY[] fetches were broken - Timezones were still set wrong when parsing dates - Using non-synchronized literals (LITERAL+) broke APPEND - Renaming maildir subfolders inserted extra "." in the middle. - Subfolders were a bit broken with maildir - Invalid PLAIN auth request crashed auth process.

[dovecot] Problems fetching messages.

Hi, I have problems reading some mail with the latest version of dovecot. I use maildir etc but it all worked before... It seems like dovecot sends something that throws Evolution off the track since the actual information is sent, but in a broken form it seems. I also get some odd chars (this is raw tcp packet decoding): "ïêa-è "ïêc-è* FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 609 EXISTS * 0 RECENT * OK [UIDVALIDITY 1049995962] UIDs valid * OK [UIDNEXT 1044] Predicted next UID A10891 OK [READ-WRITE] Select completed.

[dovecot] Corrupted index
by Mark E. Mallett 03 May '03

03 May '03

Hi- Still getting a bunch of these: Apr 30 13:45:23 mercury mem[11056]: pop3(user1): Corrupted index file /users/78/user1/Maildir/.INBOX/.imap.index: used_file_size larger than real file size (4032 vs 1608) and the occasional: Apr 30 13:08:53 mercury mem[13507]: pop3(user2): Corrupted index file (in-memory index for /users/e0/user2/Maildir): Filename mismatch for UID 1: 1051720748.28556.mercury.mv.net vs 1051715695.29601.mercury.mv.net Most of the time (but not always) the .imap* files are relatively old and apparently created by the test5 or older recent release. The errors persist in the logs until I manually remove the .imap* files, which are subsequently recreated upon the next access (without the error being logged, at least not right away). I had the impression that a "Corrupted index file" would cause the index files not to be used, and in fact recreated. Apparently not? If there is an error that causes the .imap* files to be ignored, shouldn't those files be removed? mm

[dovecot] Message causing pop3 crash
by Mark E. Mallett 03 May '03

03 May '03

Hi- Found a message that will generate a pop3 coredump when using mbox format. It seems to do with the fact that it has a mime part with a line that's 10,000 bytes long. However, that doesn't seem to be the only factor. Adjusting the size of the mail header seems to cause different kinds of crashes. I'll avoid attaching the message here but I've put it at http://www.mv.com/users/mem/x/badmail Reproducing it here on a BSD/OS system involves something like: (login to a virgin account or one you don't care about) % wget http://www.mv.com/users/mem/x/badmail % rm -rf .imap % MAIL=mbox:`pwd`/badmail % limit coredump 10m % /usr/local/libexec/dovecot/pop3 quit at which point you should get some errors and/or a coredump. You may need to do it twice (i.e. let it create the .imap/ index structure first). If you can't make it happen I can send along more info. -mm- (and yes, this was a real mail message, albeit a spam, except that I simplified it some and replaced all of the content with "x" characters)

[dovecot] Debian packages for 0.99.9
by Jaldhar H. Vyas 30 Apr '03

30 Apr '03

I uploaded the new version to sid today. Apart from the new version a big change is that it has now been split into 4 pieces. dovecot-imapd and dovecot-pop3d are the imap server and the pop3 server rspectively. They are seperate so you can install one without the other. dovecot-common contains the files they both use. dovecot is just a dummy to ensure smooth upgrades for users of older versions. As there are new packages, they will take a while to show up i the archive so I'm temporarily making them available from http://src.braincells.com/debian/sid/dovecot/ or deb http://src.braincells.com/debian sid/ deb-src http://src.braincells.com/debian sid/ via apt-get. but unless you have a burning need to upgrade, I recommend you just wait a few days. A backport to woody is also available, add deb http://src.braincells.com/debian woody/ deb-src http://src.braincells.com/debian woody/ to your sources.list. One problem I found with installing on woody is that the first time you do apt-get install dovecot, it gives you an error because /etc/dovecot.conf is no owned by dovect-common instead of dovecot. It will work correctly the second time you run the command. -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

[dovecot] 0.99.9 release candidate 1
by Timo Sirainen 28 Apr '03

28 Apr '03

0.99.9 should really be released soon. There's been quite a lot of important fixes since 0.99.8.1. There's still some recent counter strangeness, but it wasn't perfect before either. mbox still doesn't necessarily notice flag changes unless they're written into index file (ie. non-Dovecots and Dovecot without index files). But it wasn't perfect before either. dovecot-uidlist file works perfectly now as far as I know. I just noticed that mbox syncing has been somewhat broken for past month. It sometimes assigned new UIDs to messages without any reason, so it was mostly just slowdown. So unless there's something really broken, I'll release 0.99.9 tomorrow. Please get 0.99.9-rc1 from http://dovecot.procontrol.fi/rc/ and see if you can break it. NEWS file: v0.99.9 2003-04-28 Timo Sirainen <tss(a)iki.fi> * WARNING: mbox rewriting works now faster, but it's less likely to notice external message flag changes (it wasn't perfect before either).

[dovecot] Using on AIX
by Adam Lackorzynski 25 Apr '03

25 Apr '03

Hi, I'm trying to install dovecot-0.99.9-test6 with gcc-3.2.2 under AIX (4.3.3) and found some problems. First, I need to define _XOPEN_SOURCE_EXTENDED to 1 in src/lib/fdpass.c and src/auth/mycrypt.c or undefine it to compile successfully. When I define _XOPEN_SOURCE_EXTENDED to 1, I get the following error while connecting: dovecot: Apr 21 17:56:44 Info: Dovecot starting up imap-login: Apr 21 17:57:19 Fatal: fd_send(5) failed: Bad file number dovecot: Apr 21 17:57:19 Error: child 39504 (login) returned error 89 This happens after a successful authentication (i.e. wrong authentications are correctly denied). Something similar happens if I define _XOPEN_SOURCE to 500 in both files. When I undefine the _XOPEN_SOURCE_EXTENDEDs without modifying the original _XOPEN_SOURCE defines, it seems to come further: imap-login: Apr 21 18:24:23 Info: Login: xxx [xxx.xxx.xxx.xxx] imap(xxx): Apr 21 18:24:23 Panic: file mail-index-data.c: line 439 (mail_index_data_append): assertion failed: ((size & (MEM_ALIGN_SIZE-1)) == 0) dovecot: Apr 21 18:24:23 Error: child 95800 (imap) killed with signal 6 but this doesn't work either.

[dovecot] quotas again
by Mark E. Mallett 21 Apr '03

21 Apr '03

A couple of notes about quotas-- I know this has been brought up before but the negative effects that occur when a user is over quota are still disconcerting. Ideally it would be best if a user could at least delete mail when in an over-quota condition. One would think it would be enough to simply ignore errors creating the index files (and use an in-memory index). However, another problem is that the mere renaming of a file from the new/ directory to the cur/ directory can cause an over-quota error if the cur/ directory has to be expanded. We see these errors in the maillog followed by an "I/O leak" message, e.g.: Apr 21 07:42:26 mercury mem[10059]: pop3(someuser): maildir build: rename(/users/3a/someuser/Maildir/new/1049919998.23875.mercury.mv.net, /users/3a/someuser/Maildir/cur/1049919998.23875.mercury.mv.net) failed: Disc quota exceeded Apr 21 07:42:26 mercury mem[10059]: pop3(someuser): I/O leak: 0x807361c (1) Apr 21 07:42:26 mercury mem[10059]: pop3(someuser): I/O leak: 0x804a1b8 (0) and then we get a report about the server dropping the connection. BTW we seem to see quite a lot of these "I/O leak" messages in other situations too, and I think it started with the test5 release (but I am not absolutely sure). What does this mean? Yours, mm

[dovecot] 0.99.9-test6
by Timo Sirainen 21 Apr '03

21 Apr '03

Just two fixes: - dovecot-uidlist file is now assumed to be changed if it's modify time is changed. before we relied on inode changing which isn't fully reliable. - mbox dotlocks sometimes incorrectly thought someone else had overridden them Known problems that I should fix: - mbox: we don't necessarily notice message flag changes by external programs (or another dovecot without index files). It's because we don't always reparse the whole mbox file when it has changed. I think I'll have to add some X-IMAP-Changelog header which describes what changes were made by other Dovecot processes. If the change isn't listed in that header, we'll fallback to reparsing the whole file. Although that's still a bit annoying since MTA just appends the new mails, we wouldn't really need to reparse the whole file then, just the new mails. - I should use link() instead of relying on O_EXCL which doesn't work with NFSv2 (or Linux's NFSv3 client). - .subscriptions and .customflags files still aren't NFS-safe

[dovecot] Folders with mail and subfolders
by Keith Edmunds 21 Apr '03

I have a maildir hierarchy (built originally with Courier-IMAP) where some folders contain both email and subfolders. Using Dovecot I cannot see the mail in the top folders: I can only see the subfolders. Is this an RFC restriction or a Dovecot restriction? If the latter, is it planned to change? Otherwise: just started using Dovecot, and I'm very impressed with the speed of it. Thanks! Keith
