[Dovecot] imaptest update
by Timo Sirainen 02 Dec '07

02 Dec '07

I finally moved imaptest to mercurial repository and added a lot of new tests to it. It now also has its own wiki page: http://imapwiki.org/ImapTest Dovecot v1.1 with dbox or cydir format is the only open source IMAP server that reports no errors with it (haven't tried non-OSS servers). Dovecot with maildir and mbox have some problems with \Recent flag handling. I guess I'll have to figure out why.

[Dovecot] Quick fix for nfs-workarounds.c
by Dean Brooks 02 Dec '07

02 Dec '07

Hi, Under Solaris 8, the rmdir() command returns EEXIST instead of ENOTEMPTY if an rmdir() is attempted on a directory with files still in it. Dovecot 1.1beta9 currently gives tons of errors in the logfile as a result of the code not checking for the right error value. The function nfs_flush_file_handle_cache_dir() in nfs-worksarounds.c probably needs to reflect EEXIST as well as ENOTEMPTY. -- Dean Brooks dean(a)iglou.com

[Dovecot] locking strategies?
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 01 Dec '07

01 Dec '07

Any known issues with these locking strategies? (RHEL 4.x default) Dovecot: mbox_locks = fcntl Procmail Locking strategies: dotlocking, fcntl() We're considering moving to all dotlocking after a recommendation from RedHat, even though we're not using NFS at all. Thanks!

[Dovecot] Received Date vs Date Header

I am trying to figure out why my mail clients are not correctly showing me the received date versus the date header date. I am using Dovecot 1.1B9. Here is a copy of the rawlog from Dovecot when I started up the client.

[Dovecot] 1.1.Beta9 deliver problem: Unknown mail storage driver raw
by Velko Ivanov 01 Dec '07

01 Dec '07

Hello, I'm new to dovecot, trying to configure a Postfix/Dovecot system. Got everything in place - smtp with dovecot SASL and imap working fine, maildir is created, thunderbird logs in successfuly .. but the Dovecot LDA gives me this error on delivery: "Couldn't create internal raw storage: Unknown mail storage driver raw". I tried searching the configuration manual, reference, google and this list's archives, but found no clue. Checked the source, but it will take me some time to figure out what is a storage driver and where is the "raw" one hiding, so if somebody could help, please .. I did it with userdb static initially - uid=dovecot_mail, gid=dovecot_mail, home=/usr/local/storage/mail/%d/%n but after reading, that some passdbs don't work with deliver&static, I moved everything to the db (found out that prefetch isn't working with deliver btw - moans about userdb_ entries not present, while the imap finds them and works happily). It didn't help. # 1.1.beta9: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot listen: mail.srv.ivanov-nest.com ssl_cert_file: /usr/local/etc/dovecot.crt ssl_key_file: /usr/local/etc/dovecot.key login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: dbox:~/Maildir dotlock_use_excl: yes maildir_copy_preserve_filename: yes namespace: type: private inbox: yes hidden: yes list: yes subscriptions: yes auth default: mechanisms: plain login user: dovecot_db passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot_mail group: wheel
