Ugh, stuff got mangled in formatting below. Anyway, I've had no luck with various permutations, so it's looking like a virtual-user setup can't make use of replication ?

I guess what I want is for it to activate replication upon ANY notification of updated emails.

• there's a single system user (vmail) that owns all the home dirs (/var/mail/domain.com/user). The virtual users ( userid @ domain.com : secretpassword) are kept in a single file (/var/mail/domain.com/PASSWD) that's unique per domain, and referenced as a static userdb :

  passdb { driver = passwd-file args = scheme=plain username_format=%u /var/mail/%d/PASSWD }

  userdb { driver = static args = uid=vmail gid=vmail home=/var/mail/%d/%n }

I know the wiki http://wiki2.dovecot.org/Replication states that user listing must be enabled, but that's not available for a static userdb. The wiki http://wiki2.dovecot.org/UserDatabase/Static also says that it shouldn't be a problem because it will use do a passdb lookup instead (except for PAM which isn't used here).

Unfortunately, it's not working. I've testing with ssh :

dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} mail_replica = remote:vmail@server2.domain.com

as well as with straight tcp (SSL for later)

mail_replica = tcp:server2.domain.com:999

/var/log/mail.err shows the problems ...

Anyone else have it working ? I'm sure it's something simple that I've just overlooked.

I'm trying to avoid switching the userdb from a nice simple static setup to something else to enable replication. Is there anyone using replication with a virtual user configuration ? How did you do it ? Actually, anyone doing replication at all - what does your config look like ?

Thanks -

D.
