Is there a way to limit in/out mail only from particular domains ? What I want is as following:
1. Deny all mail in/out access for all domains.
2. Provide access for the designed domains.
The idea is the same as using tcp wrapper, but I can't found a way to do item 1. Sendmail only allow per domain/network blocking/relay.
I want a remote office's mail server only communicate with the head office and some known domains.
Happy new year for all list member.
