i telnetted into port 25 (not sure if this is the machine you wrote about
tho) and got this:
220 info.load-otea.hrdc-drhc.gc.ca ESMTP
mail from: <[EMAIL PROTECTED]>  
250 ok
rcpt to: <[EMAIL PROTECTED]>
553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)


if you telnet from a machine that is in your relayclients, you wont get
the 553, could that explain it?

if someone sent mail(s) to non-existent_users@your_machine with a
non-existing envelope sender adress (as spammers often do), the mail
failure notes could not be delivered and would bounce ...

Our rcpthosts file only lists our domains.
When I telneted into port 25 however and tried to mail from: a remote
address and rcpt to: a remote address I recevied a 250 ok.
