Sorry, I just got a bit disappointed after reading the the web page first. Your lines of code comparisions just seemed to imply that your server does everything that others would but with only a fraction of code. There was also something about Dovecot's design being too complex, so I thought you might have solved those problems more elegantly. When you write something from scratch, I think it's a good idea to design it so that it's superior to existing implementations in at least some ways, not just make a clone with slightly different coding style. If all you wanted was a clone with some changes (and better maintainer), forking the project would be much smaller job. Well, here's some design thoughts: Maildir implementation could be hidden behind a class to access it. That would keep the ugly details hidden from the rest of the code, as well as allow easily implementing other mail storages. Restricting yourself to only plaintext authentication doesn't sound very good plan. Separating the pre-login process from post-login process would probably be a good idea to keep their functionality completely separated. It would also be easier to audit the pre-login code if you knew exactly what there is. After logging in, you could just exec() the post-login process.

I just thought you'd rather want to see it now than months later in google. I know I would. I didn't think it was really relevant to your mailing list, but if you say so..

Indexes make Dovecot comparable to Cyrus in speed, but updating them isn't required so it's still drop-in replacement for UW imapd and Courier. Index files themselves aren't really required either, but there's no option currently to disable them. > It even recently included a POP server. What's the reasoning there? Someone wanted it so it'd be easy to run both POP3 and IMAP servers without having to configure them twice. I don't see any harm in it anyway, it took only few hours to write, it's optional and doesn't take much space in sources.

Hi Bit of a newbie to imap servers re: the article on webmonkey! http://hotwired.lycos.com/webmonkey/03/04/index3a_page4.html?tw=backend Been trying to set up SSL support with the latest ver. of dovecote I'm guessing that the following line from STDOUT is the problem. How to fix it is beyond my grasp currently. checking for SSL_read in -lssl... (cached) no Any ideas. ttfn Mark

[dovecot] 0.99.8-test3
by Timo Sirainen 11 Feb '03

It includes full LDAP support now, can anyone test if it really works? It has worked with some of my tests, but I don't know too much about LDAP so I might have missed something important. The authentication problem in test1 and test2 is also fixed now.

[dovecot] 0.99.8-test2 released

Fixes several smaller bugs. Finally works with FreeBSD (tested with 4.7 and 5.0). I think there's still some problems with authentication failing sometimes due to memory/ipc corruption. I haven't seen those today, but I don't think I've fixed that either.. One behaviour change is that if default_mail_env isn't set and mbox format is detected (~/mail dir), /var/mail/user or /var/spool/mail/user is used as INBOX if found.

Dear Timo, What do you think of this? Fyi, I've been getting the same thing lately and I'm wondering if gnutls is to blame? (i've had inexlicable SIGSEGVs in other apps before due to it.) Tomorrow I'll try with openssl but I was wondering if you had any other ideas? -- Jaldhar H.

First of all thanks for maintain such a good imap server. It's trully fast and lightweight!!! I was trying Courier, but it is not very interoperable with others linux tools like procmail and others, and uw-imapd performance was really bad. I only have one problem: If I put a lot of folders to check in mutt the imapd server closes de connection saying in the logs: Jan 31 02:50:25 www imap-login: Login: bisho Jan 31 02:50:44 www imap-master: child 22234 (imap) killed with signal 11 It only happens when mutt is configured with a lot of folders. Maybe covecot loads too much indexes in memory and reachs some limit, but I have readed carefully the conf file and hadn't found anything related. Do you have any thought about that?

[dovecot] Dovecot on FreeBSD
by Karo Salminen 06 Feb '03

06 Feb '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I built Dovecot (0.99.5) from Ports on FreeBSD 5.0. The mail client (Kmail) cannot login and it complains that authentication process died. The only thing in the logs is: Feb 2 18:13:01 karo imap-login: Disconnected [client-ip] I tried also passwd authentication method, but its symptoms are the very same. My configure can be found at http://people.jyu.fi/~kaeesalm/dovecot.conf I also tried CVS version in hope of fix and more comprehensive debug messages. The compilation failes when it tries to look for passwd.h even though I set - --disable-passwd and --without-passwd to configure parameters. Could someone fix that. - -- Karo Salminen -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) iD8DBQE+PUX0vt6lNXuj7xcRAp70AJ0R+zhmgF+WBaXaX2V2j+07eVyJRACgh6Ze Pmep2Uy2OnVe/EVuo9O3b80= =eqOO -----END PGP SIGNATURE-----

[dovecot] 0.99.8-test1 released
by Timo Sirainen 04 Feb '03

04 Feb '03

I think all of the reported bugs are again fixed in CVS, so I made a tarball of it. I'd like to hear if there's any problems with it. Here's the most important changes: v0.99.8 2003-02-xx Timo Sirainen <tss(a)iki.fi> * NOTE: Configuration file has changed a bit: auth_userinfo was replaced by userdb and passdb. *_port were merged into *_listen. Disabling listening in imaps port is now done by changing protocols setting. + Fully featured POP3 server included. Disabled by default. + Support for LITERAL+, MULTIAPPEND and UNSELECT extensions. + Internal API cleanups made Dovecot faster and take less memory + auth_verbose logs now all authentication failures + Support for Solaris 9 sendfilev() (not really tested) - COPY now behaves as RFC2060 says: "If the COPY command is unsuccessful for any reason, server implementations MUST restore the destination mailbox to its state before the COPY attempt." - maildir_copy_with_hardlinks = yes was broken. - mboxes in subfolders weren't selectable. - STORE didn't accept multiple flags without () around them - PLAIN SASL-authentication was a bit broken. - IMAP dates were parsed a few hours wrong - If auth/login process died unexpectedly at startup, the exit status or killing signal wasn't logged. - mbox parsing might have crashed sometimes - Next command after STARTTLS was ignored which left the connection stuck sometimes - STATUS command removed \Recent flags from messages - Several bugfixes to SEARCH command, especially related to multiple search conditions

[dovecot] Recent messages
by Jaime Medrano 03 Feb '03

03 Feb '03

Dovecot seems to manage \Recent messages in a weird way. When a STATUS command is performed in a mailbox, then the \Recent flag of its messages disappear and latter STATUS commands report that there are no recent messagges. I don't know exactly the behavior of the RFC. But other imap servers (UW-imapd, Netscape Messenger...) report the same number of recent messages when two STATUS commands are performed together. -- Jaime.
