Dear fixers,
My postfix ability has dissapated over many years without use :-(
I tried and failing to REJECT an unwanted domain from accessing postfix
through this in main.cf
Does anything show in the mail logs when it receives an email from the
blocked domain that could give a clue? Any warnings on trying to access
the sender access map? It is also possible to turn on full debugging in
the logs which will explain postfix decision process when deciding to
accept or reject an email. It shows step by step each matching attempt
between the address and the records in the maps.
