postfix outgoing mail fail from outlook express
There is no problem with sending/receiving mail from the postfix mail server. The problem is from outlook express to other mail servers. When the outgoing mail fail, the message from outlook express just store in postfix user mail box on my mail server with an error "Recipient address rejected: Relay access denied." Is there something in the postfix main.cf or other files that need to be change to make this happen? Thanks in advance!
