dovecot - Jan 2015 - doveadm sync different users

Hi all,

The command below works to Sync a specific user between Server A and Server
B.
> doveadm sync -u user at mydomain.me tcp:new-server.domain.de
How do i need to modify the command, to sync user1 at domain.me at ServerA and
user2domain.me at ServerB? In my case the usernames needed to sync, are not
the same.

thanks in advance,
Jonas
