chris@isbdGandi$ postconf -d myhostname mydomain myorigin
myhostname = isbdGandi.isbd.uk
mydomain = isbd.uk
myorigin = $myhostname
... and:-
chris@isbdGandi$ hostname
isbdGandi.isbd.uk
chris@isbdGandi$ dnsdomainname
isbd.uk
chris@isbdGandi$ hostname -f
isbdGandi.isbd.uk
chris@isbdGandi$
With the system configure like this postfix sends mail for 'chris' to
'ch...@isbd.uk' which isn't very helpful, I need it to be sent to
'ch...@isbd.co.uk'.
The above is with hostname set to the fqdn by running 'hostname
isbdGandi.isbd.uk' as root. However this isn't persistent, rebooting
sets hostname back to just isbdGandi.
If I reboot and don't explicitly set hostname I see:-
chris@isbdGandi$ hostname
isbdGandi
chris@isbdGandi$ hostname -f
isbdGandi.isbd.uk
chris@isbdGandi$ dnsdomainname
isbd.uk
chris@isbdGandi$ postconf -d myhostname mydomain myorigin
myhostname = isbdGandi.localdomain
mydomain = localdomain
myorigin = $myhostname
Obviously postfix uses localdomain as the domain and mail gets
rejected. The configuration with just isbdGandi as the hostname seems
to be the default/right way that Linux systems expect to be.
