This is a brand new exchange 2000 w/sp3 install with the default settings. I get the following after attempting to send from the outsde: .net 007: This e-mail message was undeliverable due to the following reason: .net 018: Each of the following recipients were rejected by a destination mail system. Note: The reasons given by the destination mail system are included to help you determine why each recipient was rejected. Solution: Attempt to resend, or contact the recipient by alternate means to let them know about the issue. Recipient: <testusr@xxxxxxxxxxxxxxx> Reason: <testusr@xxxxxxxxxxxxxxx>, Recipient unknown I've forwarded port 25 on my router and tried telneting in but wasn't able to be authenticated with my user account. I've also confirmed that my iSP, Bellsouth, isn't blocking port 25. Any responses are appreciated. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: mark@xxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
