[Dovecot] Dovecot replication, no updates on message deposit

[Milan Cvetkovic]

If anyone is interested - I found the problem in my setup:

 > protocol lda {
 >    mail_plugins = " sieve"
 > }

needs to have both "replication" and "notify"

protocol lda {
     mail_plugins = " sieve replication notify"
}

Maybe it is just me, but the Replication wiki page is not detailed 
enough. I had lots of problems trying to figure out which process runs 
on which machine, and in the context of which user.

For example, the first note mentions that "doveadm user '*'" has to 
work. It does not the context when this command would be running. This 
is important, because it takes 2 steps to configure it properly:

- to make sure the command runs at all - configure the userdb properly
- to make sure the UNIX user account which would be running it has
   the right to do it.

As a result, there are couple of posts on this list bumping up 
permissions to various sockets/fifos in /var/run/dovecot directory, 
probably in attempts to let 'vmail' user run "doveadm user '*'". And I 
still don't know if 'vmail' user runs it or not...

exim is configured to use dovecot's deliver as LDA.
