Setting up Postfix to handle mail for a virtual domain and forward it to external mailboxes is pretty easy. Here’s an example for a few domains:
/etc/postfix/main.cf
virtual_alias_domains = hash:/etc/postfix/mydomains
virtual_alias_maps = hash:/etc/postfix/virtual |
/etc/postfix/mydomains
foo.com OK
foo1.com OK
foo2.com OK |
/etc/postfix/virtual
frank@foo.com frank@gmail.com
jane@foo.com jane@earthlink.net
jim@foo1.com jimmy@yahoo.com
peter@foo2.com pete@hotmail.com |
Remember, each time you edit /etc/postfix/virtual, do the following:
postmap /etc/postfix/virtual /etc/postfix/mydomains postfix reload |
