They do reverse lookups of your mail server. I didn't have a reverse DNS entry and for testing purposes I had the admin add my server to his hosts file. That fixed the problem. I have since added the reverse DNS entry. -----Original Message----- From: Hutchins, Mike [mailto:[EMAIL PROTECTED]] Sent: Friday, September 06, 2002 1:59 PM To: Exchange Discussions Subject: RE: host unreachable certain address (domain ppco.com) -----Original Message----- From: Martin Blackstone [mailto:[EMAIL PROTECTED]] Sent: Friday, September 06, 2002 2:57 PM To: Exchange Discussions Subject: RE: host unreachable What's the domain name??? -----Original Message----- From: Tener, Richard [mailto:[EMAIL PROTECTED]] Sent: Friday, September 06, 2002 1:46 PM To: Exchange Discussions Subject: host unreachable Hello, I have a problem with guy at my job, he cant send to a certain address (domain ppco.com) he gets a returned failure saying host unreachable. I sent a test message to this address and looked in the queue on the server (exchange 5.5 sp6) and its just sitting there. We dont have problems sending to anyone else. Also i sent a test message from my hotmail account and told the guy to reply and he did. Is the problem related to maybe this person having a reverse lookup zone and us not having one. Any help would be appreciated.
