#5.7.1 smtp;550 5.7.1 message does not comply with required standa

One of my users is having his replies to an outside address returned to him

as undeliverable. The NDR displays this message:

#5.7.1 smtp;550 5.7.1 This message does not comply with required standards.

Interestingly, I (in the same domain, using the same Exchange Server) am

able to e-mail the address successfully, and the user has e-mailed the

address successfully in the past. I found one mention of this issue on a

non-MS discussion forum, and the workaround is apparently to remove RE: from

the subject line before sending. I haven't tested this exactly yet, but it

would explain why my messages to the address went through. Any ideas why

this is happening, and if there is a more permanent solution rather than the

"remove RE:" workaround?

      Why not just ask the other admin (the one that sends the meaningless

      error status -- *what* standard, out of hundreds of RFC's, does the

      message not comply?) for an explanation?
