[Dovecot] mbox to maildir batch conversion
by Mike Hobbs 02 Feb '09

02 Feb '09

Hello, I'm upgrading my mail server from UW to Dovecot and I'd like to convert from mbox to maildir. I've successfully convert myself and a few other users with the mb2md script. All is well. My question is, I have somewhere around 500 users and about 122gb of mail folders to convert (this does not include the inbox at /var/mail). mb2md needs to be run as each user to convert. Are there any programs or scripts out there that will allow me to convert everyone at the same time? I know there is a Dovecot plugin to convert mail, but we didn't want to use this option. I'm sure someone on this list was in the same situation as me, how did you handle a massive conversion? Any help or suggestions is much appreciated!

[Dovecot] v1.1.10 released
by Timo Sirainen 02 Feb '09

02 Feb '09

http://dovecot.org/releases/1.1/dovecot-1.1.10.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.10.tar.gz.sig v1.1.9 wasn't such a great release. Once again: Would be great if someone started a proper testing suite so releases could be tested.. - Maildir: Keyword handling was somewhat broken in v1.1.9 - userdb prefetch was broken with blocking passdbs in v1.1.9 - dict process didn't always die with the rest of Dovecot - dict quota was somewhat broken with pgsql

by Mathieu Kretchner 02 Feb '09

02 Feb '09

Hello all, I've configured a dovecot server in proxy mode. It seems to work well but. I've tested managesieve with squirrelmail and it's working correctly but I can't connect to cyrus sieve server : timsieved Does anybody here have configure a sieve proxy to do this ? Or is it a normal behavior and dovecot sieve proxy can't speak with cyrus sieve ? Thanks.

Moving dovecot to the nfs server directly solved all my weird problems.

[Dovecot] problem with some mailboxes (failed: Is a directory)
by mikie＠x.org.pl 30 Jan '09

30 Jan '09

I have this problem with some mailboxes (actually Maildirs) on my system. After some user's activity there is following information in dovecot logs: Jan 29 16:24:28 mailserv dovecot: IMAP(username): unlink(/var/spool/mail/imap/user/username/Maildir/cur/Sent:2,ST) failed: Is a directory User can not connect to his account neither via POP3 nor IMAP. There is one workaround I know which is: rm /var/spool/mail/imap/user/username/Maildir/dovecot.index* But after some time (some activity of user) the problem comes back. Mikie

[Dovecot] dovecot-1.2-managesieve "make install" ignores Dovecot's prefix
by Steffen Kaiser 30 Jan '09

30 Jan '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm trying to compile dovecot-1.2-managesieve from hg repo with Dovecot v1.2 and I found that managesieve uses another "install" target/prefix than I've configured in Dovecot. Is this intentional? Because you must specify the compiled Dovecot sources, is managesieve just "loosly" connected to Dovecot so it would survive a Dovecot (minor) update, or do I need to compile managesieve each time as well? If I need to compile each time, managesive should default to install into the same directory than Dovecot, shouldn't it?

[Dovecot] managesieve/README sieve_storage doc confusion
by Steffen Kaiser 30 Jan '09

30 Jan '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, http://hg.rename-it.nl/dovecot-1.2-managesieve/file/tip/README contains the paragraphs (line 47): " mail_location = If, for some inobvious reason, the sieve_storage remains unset, the managesieve daemon uses the specification of the mail_location to find out where to store the sieve files. However, this is provided only for backwards compatibility and you should always use the sieve_storage setting in stead. Additionally, the ManageSieve service uses the following settings from the plugin section of the config file. These settings are the ones used by the Sieve plugin. sieve_dir = This specifies the path to the directory where the uploaded scripts are stored. Scripts are stored as separate files with extension .sieve, all other files are ignored when scripts are listed by a ManageSieve client. If this setting remains unspecified, the mail_location setting is used as explained above. " Because sieve_storage is not mentioned anywhere else in the document and because of this discussion: http://dovecot.markmail.org/message/kzjpwdhyqhdn53zd , I suspect that sieve_dir is the older naming of it. However, the source code uses getenv("SIEVE_DIR") in lib-cmusieve, so this assumption is probably wrong. What's the correct meaning and placement of sieve_storage and sieve_dir ?

Or was it you? Anyway, dovecot-auth doesn't know how many users are logged in so if the problem really is 21 *concurrent users* instead of n logins/ second, I find it highly unlikely that the problem is with authentication. My guess is that this has something to do with NFS. Perhaps start Dovecot with strace -tt -f dovecot and then when it's slowing down see what syscall it says is blocking.
