dovecot - Sep 2016 - Setting hostdomain

Hi all,


Preparing for a replication setup, I read (at the bottom of 
<http://wiki2.dovecot.org/Replication>) that `dovecot --hostdomain` should
give a different output on the two servers. This is not the case for me: both 
give "localhost". I'm trying to change my configuration to set the
hostdomain
to another value, but I can't find how to do this.

I tried:

? setting the environment variable DOVECOT_HOSTDOMAIN=mydomain in 
/etc/default/dovecot (which is read by the init script);

? adding the line
import_environment = TZ DOVECOT_HOSTDOMAIN=mydomain
to dovecot.conf;

? the combination of both of the above.

However, after restarting dovecot none of these changes seem to have any 
effect: `dovecot --hostdomain` still returns "localhost".

This is with dovecot version 2.2.13.

How should one change this setting?


Thanks,

Arie

whats the output of 'hostname -f'

whats in your /etc/hostname and /etc/hosts?

there was a thead a few weeks ago on how to have dovecot use a different 
hostname than the system hostname see

That was indeed the problem. The output of `hostname -f` was
"localhost",
indicating how dovecot gets that result as well for its "hostdomain".

Changing the first line of /etc/hosts to
127.0.0.1      full.domain.name nameofthisparticularcomputer localhost

, `dovecot --hostdomain` now returns "full.domain.name", as I wanted.

Thanks a lot for your quick responses Christian!


Kind regards,
