[Dovecot] dovecot vs cyrus, uw, etc.
by Scott Klein 13 Nov '03

13 Nov '03

I've been doing research on switching our current e-mail server (qpopper, sendmail) to imap. The decision on which server to use is essentially down to Cyrus and Dovecot -- I like Cyrus' approach to a lot of things, but the "blackbox" nature of it makes some niceties like using spamassassin and procmail difficult, or at least counterintuitive. Dovecot seems to play nicer with other apps. I'm a bit concerned with stability, though. Although we don't have a lot of users (about 60) they're all very big e-mail users -- my users rely on their e-mail more than on their phones. We can't afford any downtime, and with our pop3 server, we haven't had any. Does anybody on this list use Dovecot to serve mission critical e-mail to an entire company? What kind of uptime can I expect? Is it genuinely ready for prime time? Has anybody here migrated from a recent release of Cyrus and can compare apples-to-apples?

[Dovecot] 0.99.10.2 for debian
by Jaldhar H. Vyas 12 Nov '03

12 Nov '03

I just uploaded it to sid. A woody backport is available from http://www.braincells.com/open/ I came across an error: giving --without-cyrus-sasl2 to the configure script doesn't work i.e. it looks for -lsasl anyway. Other than that, it seems to be working fine. -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

[Dovecot] PATCH: CRAM-MD5 for Dovecot
by Joshua Goodall 11 Nov '03

11 Nov '03

Hi Timo, Mozilla 1.5 doesn't understand DIGEST-MD5; it only speaks CRAM-MD5 or PLAIN. Maybe other clients have the same problem. My users like Mozilla, so I wrote new code for Dovecot to speak CRAM-MD5, using your mech-digest-md5.c as a reference. Attached diff in two formats i) for current CVS ii) against last release both tested and working with Mozilla and KMail's CRAM-MD5. I don't know if I've caught precisely the coding style you use for Dovecot. I hope so, but I'm unsure if I've used your string and buffer libraries properly. Please enlighten me if you have time. Would you consider including this in the next release?

[Dovecot] Problems with Linux 2.6
by Aredridel 10 Nov '03

10 Nov '03

I'm running Dovecot under PLD GNU/Linux, on two servers. Under kernel 2.4, it works wonderfully. Under 2.6, I get this in the log: Nov 9 21:36:38 polis dovecot: Dovecot starting up Nov 9 21:36:39 polis imap-login: setuid(97) failed: Resource temporarily unavailable Nov 9 21:36:39 polis imap-login: setuid(97) failed: Resource temporarily unavailable Nov 9 21:36:39 polis pop3-login: setuid(97) failed: Resource temporarily unavailable Nov 9 21:36:39 polis pop3-login: setuid(97) failed: Resource temporarily unavailable Nov 9 21:36:39 polis dovecot: Login process died too early - shutting down Nov 9 21:36:39 polis dovecot: child 32404 (login) returned error 89 Nov 9 21:36:39 polis dovecot: child 32405 (login) returned error 89 Nov 9 21:36:39 polis dovecot: child 32406 (login) returned error 89 Nov 9 21:36:39 polis dovecot: child 32408 (login) returned error 89 Nov 9 21:36:39 polis pop3-login: fd_send(-1) failed: Broken pipe Any ideas? the setuid32() call is returning EAGAIN, though I have no resource limits on user nobody (nor does it work as a dovecot user).

[Dovecot] openssl decryption failed
by Tom Allison 09 Nov '03

09 Nov '03

I've got dovecot working on imap But when I try to run imaps I get: imap-login: Nove 08 19:11:19 Warning: SSL_accept() failed: error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac [192.168.1.103] Now I'm not sure if theres any difference here, but I don't have string for 'login = imaps' or 'login = pop3s' to match with my protocols string I also don't have any specific imaps_listen interface defined, but since there's something in the logs, I assume that this is not a problem. SETUP fluffy:~ # egrep "^\w" /usr/local/etc/dovecot.conf base_dir = /var/run/dovecot/ protocols = imap imaps pop3s log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.info login = imap login = pop3 verbose_ssl = yes auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root auth_verbose = yes

[Dovecot] openssl config.
by Tom Allison 09 Nov '03

09 Nov '03

I checked and I do have the openssl-devel rpm installed SuSE 8.2 openssl-devel-0.9.6i-12 openssl-0.9.61-19 dovecot 0.99.10 ./configure --with-ssl-openssl At the end of the configuration it says ssl support == 'no' :(... I was able to get pam support by picking up the pam-devel modules as suggested. But I got stuck here. After reading up a bit on imap, it seems reasonable to have both imap and imap-ssl support. imap for localhost connections (like squirrelmail) and imap-ssl for everything else.

[Dovecot] 0.99.10.1 RC
by Timo Sirainen 08 Nov '03

08 Nov '03

Available from http://dovecot.fi/rc/ While still waiting for .11 with index file rewrites to stabilize, here's a release candidate for 0.99.10.1 which is basically 0.99.10 patched with most of the simple bugfixes from CVS. Some bugfixes such as LIST's children-flags were done with larger rewrites so I didn't try to apply them. All the changes are listed in ChangeLog. The important changes are: * mbox: \Draft and \Deleted flags used opposite flag chars in X-Status header. We were incompatible with other mbox accessing software. WARNING: Upgrading from previous version doesn't automatically swap the flags, so be careful not to accidentally expunge messages that had their \Draft flag changed to \Deleted. * Configuration file changes: - Whitespace at end of line is stripped, use quotes if you need it - # comments are supported after key=value lines. if you need '#' character, quote the value - Both " and ' quotes are supported. If you need to use them, '\' can be used for escaping. - mbox: COPY into same mailbox didn't work and could have corrupted the mailbox - Using Dovecot without index files would crash after using a while - Partial BODY[header] or BODY[part] fetches were buggy if client requested more data than was available in the header/part. - Partial BODY[...] fetches were buggy with messages that had CRLFs - Some BODY and BODYSTRUCTURE replies missed data for message/rfc822 MIME parts causing clients to break - SORT (SUBJECT) was buggy - Timezone fixes with Date-header

[Dovecot] [POP3] RFC2449 conformance?
by Matthias Andree 08 Nov '03

08 Nov '03

RFC2449 Section 5 ("Capabilities available in the AUTHORIZATION state MUST be announced in both states.") requires that POP3 extensions offered in Authentication state MUST be offered in Transaction state as well, this affects the "SASL" extension. This is a CVS version that is a couple of days old (the old 0.99.10 wouldn't run on Linux 2.6 because it has tighter resource limiting): +OK dovecot ready. capa +OK CAPA TOP USER UIDL RESP-CODES SASL PLAIN . user SECRET +OK pass VERYSECRET +OK Logged in. capa +OK CAPA TOP USER UIDL RESP-CODES . quit +OK Logging out. -- Matthias Andree
