Are subdomains in mydestination redundant?

2010-11-23 Thread Chris G
Currently my mydestination line looks like:- zbmc.eu, dps.zbmc.eu, localhost This is on the mail server which receives E-Mail from the 'outside world' from whose point of view my system is zbmc.eu. Is the dps.zbmc.eu entry actually necessary or will mail for dps.zbmc.eu be accepted anyway be

myorigin, myhostname and mydomain usage behind a NAT router - what's the best approach?
