Thanks for the tip and the links you provided me. The Standard Configuration Readme provided a lot of insight!
This is how my main.cf is set up and seems to work, but it is not correct according to what I read earlier. /etc/postfix/main.cf mydestination = example1.com, genex.example1.com, localhost.example1.com, localhost virtual_alias_domains = example2.org, localhost.example2.org genex.example2.org virtual_alias_maps = hash:/etc/postfix/virtual /etc/postfix/virtual l...@example1.com legg t...@example2.org legg So I changed the main.cf to this /etc/postfix/main.cf mydestination = localhost virtual_alias_domains = example1.com, genex.example1.com, localhost.example1.com, example2.org, localhost.example2.org genex.example2.org virtual_alias_maps = hash:/etc/postfix/virtual Upon instating these changes, mail to l...@example1.com gets returned back. User unknown in virtual alias table. Any suggestions how this can be set up in a way that is proper, robust and still delivers mail?
