Unable to send SMTP to cobalt shared server

[bpassmore]

Wierd Error when sending via Exchange 2000 (Outlook XP) to certain reciepients.
I can send to some but not to others:

THe destination domain is enstep.com - but in the server logs it shows alldredgeproductions.com (probably same IP different virtual server) but the curious part is that it look slike the conenctor is maniplulating the destination address to be the sender's address - or am i reading it wrong.




CLIENT MESSAGE:
FROM User: AndrewJackson@gulfcoast.local (internal domain with andrewjackson@gulfcoastinc.com public domain address)

TO User: Brett.Passmore@enstep.com

Does your mail go out with the gulfcoast.local address as the from: address? If so you need to modify your recipient policy so that the gulfcoastinc.com domain is your primary smtp address. This could be causing problems if the recipient mail server is doing reverse lookup for incoming messages. It would not be able to resolve gulfcoast.local and would reject mail from it. That log does look kinda weird, though.
