dovecot - May 2011 - Error messages in log

Hi,

I would like to eliminate some of the error messages which appear in my 
dovecot logfile.

I already understand that the message:
doveconf: Warning: SSL is disabled because global ssl=no, ignoring 
ssl=yes for subsection
is fixed in the current development code.

However, I also get a lot of:
lda(peter): Error: User peter doesn't have home dir set, disabling 
duplicate database
Is there a way to eliminate/supress these messages?  I'm operating with 
virtual users, so checking for a home directory doesn't make a lot of 
sense. Is there a setting in the .conf file which can control this?

Possibly more concerning is this message:
May 10 23:31:23 imap(peter): Error: 
link(/mnt/user/Maildir/peter/dovecot.index.log, 
/mnt/user/Maildir/peter/dovecot.index.log.2) failed: Function not 
implemented
I'm not sure exactly what I was doing at the time - probably 
experimenting with Sieve filters.  Has this compromised my maildir?  I 
have already disabled copy with hard links - is there another 'hardlink'
setting available?

Thank you for any advice!

Basically you are nesting homedir/meta data inside the Maildir root. This is
where the errors stem from. Sieve scripts and index data should not
reside within same.

This is a bit overcomplicated. Try using a construct like:

 mail_location = maildir:~/Maildir

http://wiki2.dovecot.org/MailLocation/Maildir

This however requires home directories to be set accordingly in the User
Database:
> userdb {
>   args = /etc/passwd.dovecot
>   driver = passwd-file
http://wiki2.dovecot.org/AuthDatabase/Passwd

With the changes in place the nesting can be avoided by simplifying:
> plugin {
>   sieve = /mnt/user/Maildir/%u/.dovecot.sieve
>   sieve_dir = /mnt/user/Maildir/%u/
 sieve = ~/.dovecot.sieve
 sieve_dir = ~/sieve

Is there a setting in the .conf file which can control this?

So apparently your fuse filesystem doesn't support link().

Nope. I don't remember what all places uses link(), but looks like at least
copying .log to .log.2 file. It doesn't really matter if it fails though.
