telnet mail.mydomain.com 25
Trying xxx.xxx.xxx.xxx...
Connected to mydomain.com.
Escape character is '^]'.
220 mydomain.com ESMTP Postfix
mail from:<vailduser@mydomain.com>
250 2.1.0 Ok
rcpt to:<other@emailaddress.com>
554 5.7.1 <other@emailaddress.com>: Relay access denied

However, piping to the "mail" command works just fine for sending/recieving mail.

it works fine after using substituting mail.mydomain.com with localhost. ill setup smtp later..
