When sending an email to a specific account i'm getting this message back:
The following recipient(s) could not be reached:
'joe schmo' on 5/12/2005 8:55 AM
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<exch.domain.org #5.5.0 smtp;550 Relaying is prohibited>
Is it me or the other server?
