[Dovecot] RFC: PAM service name change?
by Jeremy Katz 23 Jun '03

23 Jun '03

It would be nice for the sake of not conflicting to have the PAM service name not be imap. Especially as the same service name is used for pop as well :) My recommendation would be to use dovecot instead. Any other opinions? Jeremy

[Dovecot] 0.99.10-rc1
by Timo Sirainen 23 Jun '03

23 Jun '03

Home again. Fixed SSL checking for Redhat 9, I hope. Could someone test if it actually works now? Also fixed a few compiler warnings. If this thing works, I'll just update the NEWS file and call it 0.99.10. http://dovecot.procontrol.fi/rc/ Near future plans include rewriting parts of index handling. At least .tree file will go, I've a _much_ better idea how to replace it. .data file is also too bloaty and it's a bit difficult to add new fields into it. I'd have to figure out some better API to access it. I've also been worrying about locking.. If we want to share indexes between many clients, lock contention will become a problem. For example a "FETCH 1:* BODY[]" could take a long time and index can't be modified while it's being done. I'm not really sure what to do about this.. Probably some more fine graned locking and maybe some kind of transaction log where changes are written if you couldn't get exclusive lock.

[Dovecot] Dovecot and LDAP problems
by Spectron International, Inc. 22 Jun '03

I'm having problems with dovecot and OpenLDAP. I installed both, and configured both. /etc/dovecot-ldap.conf exists and I modified dovecot.conf to have... auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot-ldap.conf ...but the log displays the following: Jun 19 13:59:15 backup dovecot-auth: Unknown userdb type 'ldap' Jun 19 13:59:15 backup dovecot: Auth process died too early - shutting down Jun 19 13:59:15 backup dovecot: child 4187 (auth) returned error 89 the auth_userdb and auth_passdb seem to be ok, so what am I missing?

[Dovecot] Bug?
by Steve Gare 20 Jun '03

20 Jun '03

Hi, Been using Dovecot for a few weeks now, must say it's very good.. I've been looking for a 'drop in' replacement for UWImap for ages! :) but just recently It's been giving me a few problem, I haven't tracked down exactly what causes the problem yet (I'm using Apple Mail on OS X 10.2.6) but after a good mail session it keep trying to log in over and over again.. Looking the the log file I find this...

[Dovecot] NetBSD pkgsrc maintanance
by tom hensel 20 Jun '03

20 Jun '03

hi all, i've taken over the maintainership of dovecot's pkgsrc on NetBSD - please send me your ideas, questions and comments related to dovecot on NetBSD. FreeBSD's port has currently some more 'features' than the pkgsrc, i'm going to add some of them - any feedback is appreciated. bye, TOM

I'm mostly concerned about what happens if the user exists in >both authenticators. I guess normally this shouldn't happen, but you >can't really guarantee that and mistakes happen.. Yes mistakes happen. Why could'nt you (we?) do like proftpd that has a parameter that give the order of authenticators first one wins. That way you could even have the same user as a real and virtual account with differents passwords > >If fallbacking happened only when user isn't found from first >authenticator, that could work a bit more safely, but I'm not sure if I >can know with PAM if check failed because user wasn't found or because >password didn't match. I don't know either. My idea is to get rid of PAM for that's although fantastic on the paper is a Linux thing that I can't even compile here.

[Dovecot] \0\n at end of lines
by Mike Grupenhoff 19 Jun '03

Since upgrading to -test11, mail fetched from imap has every line terminated with a nul and a newline ("\0\n"). This also happens with -test12. It seems to happen with both mbox and maildir. I'm running on NetBSD/sparc (NetBSD-current as of April 1, 1.6Q). If it matters, I have "mail_save_crlf" set to "no" and "mail_read_mmaped" also set to "no". I can't find any other options that look like they could be relevant. Any ideas? Thanks, mike

[Dovecot] 0.99.10-test12
by Timo Sirainen 19 Jun '03

19 Jun '03

http://dovecot.procontrol.fi/test/ I should have released 0.99.10 already I think.. There's just two annoying problems that I think should be fixed first: - PAM: If user gives a wrong password, dovecot-auth process sleeps for two seconds, blocking everyone else who are trying to authenticate at the time. So using PAM isn't very good idea at the moment. - OpenSSL problems. Are they really my fault? I have no idea what I could be doing wrong. Maybe some compile option is wrong? Also I should try to use pkg-config to get compile flags if it exists in configure. The new things in -test12 then: - We sync mailbox less often. Only NOOP and CHECK will force a mailbox sync now. Other commands do it also but only if mailbox hasn't been synced in last 5 seconds. Maybe this reduces some I/O. At least a bit less stat() calls :) - Dirty maildir flag flushing work now. Meaning that if you change message flags but rename() fails because you're out of quota, the flags are changed in index file and dirty-flag is set. Once in a while it tries to flush the dirty flags by rename()ing the file again. - IMAP RFC requires that NUL characters are never sent to client. We do now the same as UW-IMAP by sending ascii 128 chars instead.

[Dovecot] 0.99.10-test13
by Timo Sirainen 18 Jun '03

http://dovecot.procontrol.fi/test/ - Hopefully OpenSSL is fixed :) - We sometimes produced invalid ENVELOPE with 8bit headers. That could really have broken things (broke it in test12). So, what's left is to make PAM work well..
