I’m running Exchange 5.5 with SP3. I can send to every address except one. That server will except mail from everyone except me. When I send mail to them, I get:

Your message did not reach some or all of the intended recipients.

Subject:test
Sent: 6/21/00 10:14 AM

The following recipient(s) could not be reached:

‘Rsapitro@barilla-usa.com’ on 6/21/00 10:14 AM
Unable to deliver the message due to a communications failure
The MTS-ID of the original message is: c=US;a= ;p=leeperderose;l=MAIL_SERVER-000621141338Z-865
MSEXCH:IMS:leeperderose:DM_DOMAIN:MAIL_SERVER 3503 (000B099C) 503 please introduce yourself, first

My SMTP Log returns this:
