[Dovecot] v1.2.6 released
by Timo Sirainen 06 Oct '09

06 Oct '09

http://dovecot.org/releases/1.2/dovecot-1.2.6.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.6.tar.gz.sig A couple of random things: - I decided to start using "hg sign" to gpg sign all releases in mercurial repository. - v2.0.alpha1 will hopefully be released in a week or two. Changes since 1.2.5: * Upgraded to Unicode 5.2.0 + Added authtest utility for doing passdb and userdb lookups. + login: ssl_security string now also shows the used compression. - quota: Don't crash with non-Maildir++ quota backend. - imap proxy: Fixed crashing with some specific password characters. - dovecot --exec-mail was broken. - Avoid assert-crashing when two processes try to create index at the same time.

[Dovecot] Proxy setup & upgrade from 1.0.3 to 1.1.7
by Adrian Wojcicki | Unternehmensberatung Wojcicki 06 Oct '09

06 Oct '09

Hi guys! I hope somebody can help me with my problem: We have a server running dovecot and proxying IMAPS connections to our internal network. This worked so far very good until we upgraded the server to a new SUSE Linux version and with it dovecot from version 1.0.3 to 1.1.7. My guess is that something changed in the way dovecot reads the user file as the configuration stayed the same: dovecot.conf: base_dir = /var/run/dovecot/ protocols = imaps disable_plaintext_auth = yes ssl_cert_file = /<pathtocertificate> ssl_key_file = /<pathtocertificate> ssl_disable = no ssl_listen = 80.149.64.98:993 log_path = /var/log/dovecot.log login_dir = /var/run/dovecot/login login_process_per_connection = yes login_processes_count = 3 login_greeting = main.xbdx.de IMAP What can we do for you? imap_client_workarounds = tb-extra-mailbox-sep mail_debug = no auth_debug = yes auth_cache_size = 4096 auth_cache_ttl = 7200 auth_worker_max_count = 30 auth default { userdb static { args = uid=5000 gid=5000 } passdb { driver = passwd-file args = /etc/dovecot/dovecot.passdb } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } mechanisms = plain login user = root count = 1 } dovecot.passdb: testuser1:::::::host=<internalip> port=143 nodelay=y nologin=y proxy=y testuser2:::::::host=<internalip> port=143 nodelay=y nologin=y proxy=y dovecot.log: dovecot: Oct 06 10:37:26 Info: Dovecot v1.1.7 starting up dovecot: Oct 06 10:37:26 Info: auth(default): passwd-file /etc/dovecot/dovecot.passdb: Read 2 users dovecot: Oct 06 10:37:27 Info: auth(default): new auth connection: pid=8135 dovecot: Oct 06 10:37:27 Info: auth(default): new auth connection: pid=8136 dovecot: Oct 06 10:37:27 Info: auth(default): new auth connection: pid=8137 dovecot: Oct 06 10:37:39 Info: auth(default): new auth connection: pid=8139 dovecot: Oct 06 10:37:39 Info: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=80.149.64.98 rip=217.91.33.32 lport=993 rport=61752 resp=<hidden> dovecot: Oct 06 10:37:39 Info: auth(default): cache(adrian.wojcicki,217.91.33.32): miss dovecot: Oct 06 10:37:39 Info: auth(default): passwd-file(testuser1,217.91.33.32): lookup: user=testuser1 file=/etc/dovecot/dovecot.passdb dovecot: Oct 06 10:37:39 Info: auth(default): passwd-file(testuser1,217.91.33.32): Password mismatch dovecot: Oct 06 10:37:41 Info: auth(default): client out: FAIL 1 user=testuser1 host=<internalip> port=143 nologin proxy pass=<hidden> dovecot: Oct 06 10:37:41 Info: imap-login: Aborted login (auth failed, 1 attempts): user=<testuser1>, method=PLAIN, rip=217.91.33.32, lip=80.149.64.98, TLS Thanks!

[Dovecot] dovecot 1.0.15 upgrading to dovecot 1.1.x or 1.2.x, and POP3 UIDL issue
by Ariel Biener 05 Oct '09

05 Oct '09

Hi, We're upgrading a cluster of servers from v1.0.15 to v1.1.x or v1.2.x. It appears that the UIDL generation mechanism has changed, and thus we'll be getting POP3 dups with users that leave mail on server (which is a nasty practice, I know). From checking the sources, and performing a number of controlled tests in various scenarios, here is the outcome: upgrade from 1.0.15 to 1.1.x (latest), UIDLs change (no change to the mail backend, that is, mbox) However, the interesting part is that if for example I read a mailbox for the first time with the 1.1.x version, and then I migrate the mailbox to a different server, running 1.1.x or 1.2.x, with Maildir or mailbox the UIDL does *NOT* change. We do not have X-UIDL headers in the mailboxes. I did every possible permutation of these tests. It appears that the way UIDLs are created in 1.0.x is different than what is used in 1.1.x and 1.2.x. (I am not talking about the format, we're using the same format in both, that is, UW compatible). Since we're a largish site (university), and we have some >60k accounts, even the smallest percentage of users who use POP3 and "leave mail on server" is a large number of angry staff members landing on our helpdesk, which is the reason why we're not migrating. Has anyone ever ported the UIDL generation algorithm from 1.0.x to 1.1.x/1.2.x to maintain compatibility ? Is there some other option that I am missing ? --Ariel

[Dovecot] Quota exceeded delivery message
by michel＠casa.co.cu 05 Oct '09

05 Oct '09

Hi I have assigned quotas to my users and in turn use quota_warning for my users send them a message saying that the level of its quota is about to be exceeded. when the quota is exceeded, the script runs again sending a message to the user and is rejected by the server. there is any way to get the message when the postmaster, is delivered to the mailbox even when exceeded the quota or simply not send it once exceeded the quota level? quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota = maildir quota_rule = *:storage=40M Another question: I've implemented recently in my work Bogofilter to mark messages as SPAM or HAM. Using dovecot as IMAP and POP3 server and deliver, there is some way to move messages marked as SPAM to a folder called spam or junk? I've heard that can be done with sieve, is this true? fileinto?
