Is your server MX host for domains that are delivered to a different
mail server?
If not:
Set relay_domains to empty.
If yes:
DO Specify ONLY THOSE DOMAINS in relay_domains
DO specify ONLY THOSE recipients in relay_recipient_maps
DO NOT specify virtual (alias or mailbox) stuff in relay_domains
DO NOT specify virtual (alias or mailbox) stuff in relay_recipient_maps
DO specify virtual alias DOMAINS in virtual_alias_DOMAINS.
