Re: Dovecot, LDAP and something akin to Postfix' "table search order" from virtual deliver.

Hi!

Just for the sake of archive completeness - I've managed to solve my
problem without any dirty hacks or something.

The key part was to rewrite recipient address before relying mail to
dovecot deliver. This can be achieved using e.g.
recipient_canonical_maps. More info can be found here:

http://pjs.name/pages/en/blog/postfix_dovecot_deliver_catchall/

Once again - thanks Maciej for your input :)

Regards,
Pawel

Quota Override

Hi People

I use the dovecot version 1.0.10 , in my config I have set a global quota 
value = 10 MB but I want to override for some users this value , getting from 
my ldap other value like = 30 MB.

Dovecot obtain this value from ldap:
(((((Feb  1 12:12:26 gandalf dovecot: auth(default): client out: OK   1       
user=michel <at> home.com  quota= maildir:storage=30240)))))

Feb  1 12:12:26 gandalf dovecot: auth(default): 
ldap(michel <at> home.com,127.0.0.1): result: mail(user)=michel <at> home.com 
quota(quota= maildir:storage)=30240
Feb  1 12:12:26 gandalf dovecot: auth(default):

auth default : passwd-file Can't open file: Permission denied

Hello,

I'm attempting to migrate from an existing dovecot .99 install to dovecot
1.0.rc15 on a fresh up to date CentOs 5.1.  I'm not sure what's causing this
permissions error on startup - I've tried 777,644, and 600 chmods but it's
always this same error:

Feb  1 12:43:05 ns2 dovecot: Dovecot v1.0.rc15 starting up
Feb  1 12:43:06 ns2 dovecot: Auth process died too early - shutting down
Feb  1 12:43:06 ns2 dovecot: auth(default): passwd-file
/var/spool/virtual/passwd: Can't open file: Permission denied

Feb  1 12:43:06 ns2 dovecot: Temporary failure in creating login processes,
slowing down for now

Here's some more information from the shell:

# /etc/dovecot.conf

login_executable(default): /usr/libexec/dovecot/imap-login

You really should go ahead and update to a release version... check the 
atrpm repository...

Make sure you follow the upgrade instructions here:

Bug handling zero-byte files in maildirs

I managed to get a bunch of zero-byte files in my maildirs today, and  
Dovecot choked completely (at least for pop3 users); It wouldn't  
download any messages at all, and the mailbox would often say "-ERR  
[IN-USE]" when doing a STAT

corrupted index?

We're seeing the following sporadically in
the log file (single line broken into separate
lines for readability):

Corrupted index cache file 
/home/user/mail/.index/.imap/INBOX/dovecot.index.cache:
invalid record size

We're running dovecot-1.0.7-2.fc8.  The imap directory
is in the user's NFS-mounted /home directory, but
doveot is running on the same host as the
/home filesystem.  There's plenty of disk space and
no other significant system problems.  The mail
index directory we rm'd a week/so ago, so doveoct
has had the opportunity to rebuild it.

Any ideas on what might be causing this?  Is this
issue anything to worry about?

thanks.

SELinux prevents accessing it.

What Dovecot version?

That error is returned for the first command after login if the mailbox
syncing failed (or locking it failed). Dovecot should have logged an
error in that case.

Anyway I don't see why zero byte files should be a problem for Dovecot.
I've often used them for testing, and just now couldn't reproduce this
problem. Maybe the actual problem is something else.

The userdb lookup is done only when giving -d dest <at> user parameter to
deliver. I don't know if mailbox_command allows that.

Why is there a space after quota=? Maybe that messes it up.
