MS 2000 server w/ 2000 Exchange

I am having difficulties with about 3 outside domains.  Anytime I try and send mail to these domains, it is held in our exchange que, and then eventually gets kicked back to the sender.  I have tried to force the connection, but to no avail.  I am trying to determine why this may be happening.  Does anyone have any ideas?

    Just a shot in the dark but is RDNS working properly for your email server?  A few ISP's have required that rDNS work for your server before they will accept email.  Other then that what are teh 3 domains you are having a problem with?

    When the email is kicked back to the sender what is the error it returns?  There should be some specific details as to why the message failed.  Also try perform some queries against those domains directly from the server.  IE etc.
