I am sure I am doing something very simple, but I cannot get postfix to accept outside mail. It is being rejected.

I have myhostname and mydomain set
inet_interfaces = all
mydestination = $myhostname, localhost.$mydomain

Which is all I can find in any docs to set, i have played with a bunch of other settings to but keep getting the mail rejected.. here is the bounce back the emails get:

Recipient address rejected: Relay access denied
Giving up on


Any help would be greatly appreciated at this time

Thank you

Postfix by default will not act as an open relay... This is what is "biting" you.

It will only relay between two "trusted" clients, and between a trusted client and a "stranger" client. It will reject anything that it thinks is between two "stranger" clients.
Left to the defaults this would probably mean that the subnet for the interface you bind postfix to (if you have more than one, perhaps all of them) would be trusted.
Try setting the network(s) explicitly with
mynetworks = x.x.x.x/m, y.y.y.y/n
where x.x.x.x/m and y.y.y.y/n would be the subnets you intend to relay for (in CIDR-like notation... 192.168.0.0/24 ...).

Tell a bit more about your topology, and how you plan to "route" mail, and perhaps we can be more specific than this:-).
