I have a domain hosted in my plusnet package. It's reeve.org.uk at the moment some spammer is spoofing my domain as a return address so I am getting lots of bounced emails.
Is there a way I can only allow the addresses I use (only firstname.lastname@example.org) to get through to my plusnet mail account. At the moment "anything"@reeve.org.uk is forwarded.
Simple answer - Yes.
All you need to do, is ensure that you have a mailbox set up for postmaster@.... and whichever others you want mail for eg. will@....
then just raise a ticket asking for the rest to be blackholed.
He presto - sorted.
