[Dovecot] 1.0-test59
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/test/ No-one had been testing 1.0-tests with Evolution? It was pretty much completely broken with messages having attachments. - test58's output stream code change were entirely wrong and caused bad breakages with mbox. - Named pipes are now treated as write-only mboxes (blocks if no-one is reading, perhaps it should timeout in a few seconds?) - FETCH BODY[n.xxx] replies were all wrong - LDAP authentication was crashing - pop3_uidl_format=%f from Andrey test60 will probably have keyword support. Its index file code is already working, with ability to set over 500k different keywords per mailbox (because message record size is limited to 65535 bytes - should be enough for everyone :). Code is still missing to notify other session about keyword changes, and storing the keywords into mbox/maildir. For mbox I can use X-Keywords header. There should probably be some configurable limit to how many keywords to set per mailbox.. Dovecot shouldn't mind if the X-Keywords header is huge, but other programs might. For maildir then.. I think I'll just implement it backwards compatible with 0.99.x, ie. store in maildir filename with a-z letters. That would make max. 26 keywords per mailbox. Except maybe I shouldn't limit it to that. The rest could be stored only in indexes. That however would make it necessary to keep indexes backwards compatible forever so data is not lost.

[Dovecot] 0.99.13-rc1
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/rc/ I guess the RCing in 0.99.12 didn't help that much. SQL/LDAP authentication crashed because memory was freed wrong. Please test so it would actually work in 0.99.13. Also fixed SEARCH UNKEYWORD which wasn't working. Also added 1.0-test's oe-ns-eoh POP3 workaround built-in.

[Dovecot] Cygwin and index code
by Johannes Berg 19 Dec '04

19 Dec '04

As I can currently only work with windows (eek) I thought I'd try dovecot there. I already sent a patch to make dovecot compile under cygwin, but it still doesn't really work, here's part of a session that I started while my maildir was totally empty (only cur/new/tmp in ~/Maildir) $ ./imap.exe * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as jmberg A01 SELECT INBOX imap(jmberg): Warning: Compressing cache file /home/jmberg/Maildir/dovecot.index.cache imap(jmberg): Error: open() failed with file /home/jmberg/Maildir/dovecot.index.tmp: Permission denied A01 NO Internal error occured. Refer to server log for more information. [2004-12-17 15:51:06] A02 LOGOUT * BYE Logging out A02 OK Logout completed. A second session (some files were created by the first) yields this: $ ./imap.exe * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as jmberg A01 SELECT INBOX imap(jmberg): Error: open() failed with file /home/jmberg/Maildir/dovecot.index.tmp: Permission denied imap(jmberg): Error: rename(/home/jmberg/Maildir/dovecot.index.tmp, /home/jmberg/Maildir/dovecot.index) failed: Permission denied A01 NO Internal error occured. Refer to server log for more information. [2004-12-17 15:52:25] A02 LOGOUT * BYE Logging out A02 OK Logout completed. I think this is probably due to the indexing code opening the .tmp file and then unlinking it and trying to re-create it while the first is still open. Or something, I really am not sure. *Maybe* the index code might be made work if it creates a new temporary file-name every time it re-creates the file, but I don't understand the code well enough (yet) to give a better analysis of the problem. However, I do not think that this is really important. I certainly don't want to run dovecot on windows (I only saw cygwin compile in the todo and since I have a cygwin setup anyway I thought I'd try). The whole thing doesn't work anyway: [after correcting users, making directories, make install...] $ /usr/local/sbin/dovecot.exe dovecot: Dec 17 16:03:17 Info: Dovecot v1.0-test58 starting up dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: Login process died too early - shutting down dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: auth(default): dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 256): Invalid argument dovecot: Dec 17 16:03:18 Error: child 2176 (auth) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2192 (login) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2212 (login) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2232 (login) returned error 89 Maybe someone cares. If not, well, I had a less boring train ride ;) johannes

[Dovecot] spam plugin
by Johannes Berg 19 Dec '04

19 Dec '04

Here's a new version, it compiles (and appears to work) except the part in "copy_reclassified". Can anyone help me (probably only Timo knows how) with that? http://johannes.sipsolutions.net/edit/Projects/dovecot-dspam-integration/ps… johannes

[Dovecot] 1.0-test58
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/test/ - Fixed APPEND hanging in some situations. Didn't happen with mail_save_crlf=yes. - Added pop3_uidl_format setting. No need to patch sources anymore if you don't want the default. Does anyone want pop3_uidl_xuidl_header yes/no setting, with fallbacking to pop3_uidl_format if X-UIDL header isn't found? Shouldn't be difficult to do.. - Added mbox_very_dirty_syncs setting which tries to avoid re-reading mbox as long as possible. - CREATE dir/ wasn't working - If login_process_per_connection=no and auth process count > 1, each auth process listens in different socket. Login processes then connect to all these sockets and send requests to them in round robin. - Multiple auth sections in config file work now a bit better. dovecot-auth might still complain about timeouts though.

[Dovecot] deploying dspam
by Johannes Berg 17 Dec '04

17 Dec '04

Hi everyone, I've been thinking of phasing out my spamassassin installation (it's hardly doing me any good these days) in favour of dspam. Now since I'm working on this anyway, I thought I'd configure it so when users get any spam, it is delivered into a special folder. I figure I need the 1.0 test series for this, so I can make that folder fixed. But, I also want to allow them to move spam in and out of that folder and dspam can learn it. Anyway, I found a message dating back a while where Timo says this could easily be implemented in a plugin (in the 1.0 test series), but I can't put my finger on how to do it. Does anyone have an example plugin that can run commands when mail is moved in or out of a special folder? Or is there any plugin-writing documentation? Thanks, johannes

I already submitted it to the dspam author but did not get any reaction so I don't know if he considered to include it. In dspam 3.0 the rule to clean up dspam_token_data was terribly stressing my system, changing it to the equivalent (I hope ;) - delete from dspam_token_data where ((innocent_hits=0 and spam_hits < 5) - or (innocent_hits=1 and spam_hits < 3) or (innocent_hits=2 and - spam_hits = 0)) and @a-to_days(last_hit) > 30; reduced the queries run time by a factor of 10 to 50 easily.
