My company has problems sending mail to one particular domain. When mail is sent to this domain, the sender gets the following message sent back to them:
This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
My company is using Ms Exchange 2003 sp2 and mail is sent outbound via a separate windows 2003 server running a IIS SMTP Virtual Server.
Upon reviewing the SMTP logs on the SMTP Virtual Server for the domain i am trying to send mail to they consist of the following entries which leads me to believe that the problem could be with the receiving mail server rejecting the mail because it does not like the BDAT command used by my Exchange server:
This i find strange as the BDAT command is only used when communication is with another Exchnage.
How someone please assist me in resolving this problem.
