You have to specify on outlook express on the mac that you want to use
authenticated SMTP.  Just like you would put a username and password in
for receiving POP3 you need to put in a username and password for the
SMTP.   If your current version of express on the mac doesn't have that
then download the latest version.

Subject: [exchangelist] Relaying prohibited for Macintosh client

I have recently secured my Exchange 2000 server from being an open
I have a Mac on my network that uses Outlook Express for a mail client. 
Since fixing the open relay issue, once in a while the Mac can't send
mail, and recieves the "cannot relay for personA@xxxxxxx" or similar
error message.  I believe that it's probably due to the fact the the mac
doesn't log on to the domain, so perhaps the server won't process the
mail because it doesn't recognize it?  Any help would be greatly
