Well after a fresh install of postfix, setting my inet_interfaces = all and restarting postfix has allowed me to telnet to port 25 with the linux box itself, through localhost and I was also able to connect a telnet session from another box on my lan to port 25. Also I gained a new error on the message that was returned: Recipient address: usr@xxxxxxxxx Reason: Remote SMTP server has rejected address Diagnostic code: smtp;554 <usr@xxxxxxxxx>: Relay access denied Remote system: dns;b-dub.org (TCP|167.206.5.68|52577|24.44.190.85|25) (cosmo.b-dub.org ESMTP Postfix) Is this a good sign? Or is this a sign that my ISP is stopping the mail? Cosmo.b-dub.org is the name of the server box, it does not have a mx or a record, should I set one up? The only forwarded port (well related to postfix) is port 25 through the linksys router do other ports need to be opened? Thanks, JP
