ThanksTeemuBy setting environment variable DOVECOT_HOSTDOMAIN the dovecot
--hostdomainnow returns the hostname.
getent hostsReturns all entries in the hosts file - including "localhost" and
the servers hostname.mydomain
So far the change has not made any problems.
Dsync, however does not seem to be doing anything.Is there a log option
available that could tell something about whats failing? The only log entries I
find is these two when starting dovecot service:masterserver:Jan 5 01:41:04
localhost dovecot: imap: Debug: Module loaded:
/usr/lib64/dovecot/lib20_replication_plugin.so
standby server:Jan 5 01:40:34 gen-omas-stb dovecot: auth: Debug: master in:
LIST 1 service=replicator

You can define what hostname dovecot uses, by setting the environment variable
DOVECOT_HOSTDOMAIN.
It would also be interesting to see what "getent hosts" returns on your
servers. Using the "hostname" command is not quite the same thing.

I can not speak for any/all clients, but I do not see how a change in the imap
server name would make clients redownload email.

This depends on how you want the syncding to be done. If it is two way
master-master, then you need to configure it on both. I think this might
probably be what you want anyway.
