[dovecot] passwd-file access
by Jesse Peterson 17 Dec '02

17 Dec '02

Using passwd-file authentication I run into some problems.. This is my passwd file: user:0cc175b9c0f1b6a831c399e269772661[34]:6660:6660:0:/some/mail/directory/user:0::: My MUA tells me after enter my user/pass that the server disconnected, OK. So I netcat into the imap server, and issue an "C: LOGIN user a" in which case I get the error "Fatal: USER environment missing". So I search for this in the src and find in 'src/imap/main.c' on line 30 it checks for the environment variable USER.. which I assume it can't find because it's not an actual system user, it's a ficticious user in a passwd-file. Any ideas? -- Jesse Peterson erage(a)softhome.net

Timo, What is the "official" way to pronounce Dovecot? Is there a meaning to the word? A background on why you chose it? -- Jesse Peterson erage(a)softhome.net

[dovecot] SSL + default_mail_env
by Jesse Peterson 16 Dec '02

16 Dec '02

in the config file i have "ssl_disable = yes", however, i get this in my LOG_MAIL syslog: "Dec 17 00:21:07 host imap-master: Can't create temporary SSL parameters file /default/configured/directory/ssl-parameters.dat.tmp: No such file or directory" I know what the error is, and how to fix it, but it's an SSL thing which should have been disable according the config file, correct? It would seem that if you surround the value given to default_mail_env in quotes (as listed in the sample config file) you get errors like: Dec 17 00:21:13 host imap(testuser): Failed to create storage with data: "maildir:/home/testuser/mail/" -- Jesse Peterson erage(a)softhome.net

[dovecot] Maildir problem..
by Jesse Peterson 16 Dec '02

16 Dec '02

I have the most interesting problem... I've compiled dovecot from CVS with a checkout on 2002-12-15 around 23:00 PST. When I select a message in my MUA I can view it and stuff, however, if I select another message, or folder, the message disappears. It appears that dovecot shortens the Maildir message name to ":2,S" and then you can't access the message from the MUA again. The same happens if you try and move a message from a foler to another folder.. Any ideas? -- Jesse Peterson erage(a)softhome.net

[dovecot] Maildir detection..
by Jesse Peterson 12 Dec '02

12 Dec '02

It would seem that dovecot cannot detect my maildir. The system DO NOT use "~/Maildir". It is arbitrary across a few systems, actualy, and am curious if there is a way to "force" in the config file where the maildir explicitly resides, much like Postfix's "home_mailbox" configuration parameter. On a side note, I compiled dovecot 0.99.4 on a NetBSD 1.6-release i386 machine, it when imap_listen is not set in the config file, it only binds to the tcp6 ::1 address. Any clues? -- Jesse Peterson erage(a)softhome.net

PAM can only be used for checking if user/password matches, so it's missing the passwd information that Dovecot needs, at least home dir and uid. Although I had been thinking of making those some global settings in config file, so you could say homedir=/var/user/$USER$ uid=imapusers. > > I've been thinking about SQL database support from the beginning. > > However it'd probably be slower and require a bit more memory than with > > the current indexes. > > ohh? I assume a database should have to be faster, but this is just an > assumption... That's mostly because of a few tricks that Dovecot does with it's index files that aren't really possible with SQL databases. Multiuser mailboxes which are modified a lot are one thing where they could be faster than Dovecot's index files because of better locking. Besides, Dovecot's indexes could be called as a simple database..

[dovecot] questions
by Farkas Levente 05 Dec '02

hi, I'm look around to find a usable imap server and find dovecot. I read all the docs, but I've got a few questions: - currently we use courier (since we find and install it quickly). can we switch from it to dovecot smoothly? or we have to convert the maildirs somehow? - I've got a few plan in my mind it it possible to do it with dovecot now or in the near future (if yes what is the estimated time)?: - authenticate from LDAP, the best would be trough PAM? - use the same user with different domain. eg: lfarkas(a)bnap.hu, lfarkas(a)bppiac.hu with the same imap server? handle more domains. - use imaps and use Digest-MD5 and/or CRAM-MD5? - put a database backend under imap and store the mails in a database. - use WITHOUT local users? it's very important! most case a user never ever log into the local system and I would not like to put them into /etc/password. - do it all the above at the same time!? thanks. -- Levente http://petition.eurolinux.org/ "The only thing worse than not knowing the truth is ruining the bliss of ignorance."

Like: imap-auth: Dec 01 17:59:32 Warning: Killed with signal 11 And if it was killed with signal 11 or 6 you should also find core file in the directory where you started imap-master?

[dovecot] Sieve
by hellhound＠geek.be 01 Dec '02

Hi all, I'm using Dovecot for some months now, and I love it! I also saw that there are 'plans' to integrate Sieve support. Well, some days ago I saw the following on freshmeat: libSieve - http://libsieve.sourceforge.net/ libSieve is a standalone library pulled from CMU's implementation of their Sieve mail sorting library in the Cyrus mail server. Either shared or statically linked, libSieve will help to bring mail sorting functionality into your mail server application without the need to reinvent the wheel. As a library, it is not intended for end users expecting a ready-to-run program. Maybe this could ease the Sieve integration ? If I got some spare time I'm going to contribute some code for it myself. greets

Thanks. I thought that would have been portable since it was in UNIX98. You could change that to RLIMIT_DATA and it should be somewhat equilevant. I'll change it in CVS so that it does both DATA and AS if it exists.
