I can send outgoing messages to from my mail server, but if I try and reply to them then I get this message back:

----- The following addresses had permanent fatal errors -----
<webadmin@linuxhosting.linuxhome.net>
(reason: 550 5.7.1 <user@my.domain.net>... Relaying

Which domain is "yours"? my.domain.net? And, is your machine the one that is causing the "Relaying denied" message?

If so, your "my_destination" variable is likely not set properly, or you need to define the delivery mechanism in the transposts file.

Can you provide more detail about your configuration, including client machines (if any), how you're sending mail, your domain name, PF configs, etc.

To Answer you questions:

1) "my.domain.net" is "mine"

2) This therefore implies that it is my machine throwing up the error hence "while talking to my.domain.net."

3) There are no client machines, postifx is configured to deliver mail directly, i sent that e-mail that got sent back from my normal ISP account, i am using a domain name provided by dyndns.org and the mail entries are setup correctly. The rest of the config, is as far as i am aware default.

Thanks Paul

"make sure this is just something like mydomain.net", thats a little problem, as i am using dyndns to act as my dns and forward my traffic, i have a subdomain of dyndns.org. can i put the full subdomain i.e site.dyndns.org

Thanks

Mark

Absolutely. In fact, that's how mine is set up. You want it set that way so that the line that says "myorigin = $mydomain" will put the right information after the @ on e-mail's originated on this machine.
