The external IP of an international Mailserver must have an DNS resolution
and from my point of view also an valid Mx entry.
A reverse DNS should also be given.
For internal Subdomains masquerading to the main domain could also incr

A few weeks ago my server’s emails sent from the postmaster user started to
bounce with the following error message:
The following addresses had permanent fatal errors ----- <user>@domain.com
(reason: 553 5.1.8 <root at server.domain.com>... Domain of sender address
root at server.doman.com does not exist)
(expanded from: <root at server.domain.com>)
It appears that my email is being blocked because there are not DNS records
for the sub-domain server.domain.com.
If this is correct how do I change the postmaster sender address from
server.domain.com to domain.com?
Or is there a better solution?
Thanks for your help,
