I have been receiving this problem more and more now and all of them are to .ca domains. All the .com domains have been fine. What do you think?

There is nothing you can do about it other than call their mail admins and ask them to straighten things out. Now, for some reason their mail server is not even picking up the call. At the same time it is an open relay. At the same time it is behind a CheckPoint firewall. So they basically have created a mess on their side. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Theo Odartei Sent: Monday, September 20, 2004 9:07 AM To: Exchange Discussions Subject: RE: exchange2003 non-delivery after joined to exchange2000 admin group Our dns was able to resolve the address as well as the mail address but there are a lot of failures on dnsreport.com site. What portion of the report do you want to see to help determine the issue? Here are the failed sessions 1 Open relay test : WARNING: mail.kpf.ca appears to be an open relay: 250 recipient ok. (kpf.ca is the destination) 2 Connect to mail server : ERROR: I could not connect to one or more of your mailservers: mail2.kpf.ca: Timed out [Last data sent: QUIT ] 3 Reverse DNS entries for MX records : ERROR: The IP of one or more of your mail server(s) have no reverse DNS (PTR) entries (if you see "Timeout" below, it may mean that your DNS servers did not respond fast enough). RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. You can double-check using the 'Reverse DNS Lookup' tool at the DNSstuff site. The problem MX records are: 94.183.145.142.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0)] 244.246.93.65.in-addr.arpa [Timeout] -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fyodorov, Andrey FTL Sent: September 17, 2004 5:18 PM To: Exchange Discussions Subject: RE: exchange2003 non-delivery after joined to exchange2000 admin group How about your DNS? Is your DNS resolving those domain names and their MX records correctly? Have you tried to do an NSLOOKUP against your AD DNS servers and compare the results vs http://www.dnsreport.com? Also your IP address could be on some spam blacklist that those domains are using, and the "5.7.1 Unable to relay" could be just their way to tell you that they don't want to take mail from you. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Theo Odartei Sent: Friday, September 17, 2004 4:52 PM To: Exchange Discussions Subject: RE: exchange2003 non-delivery after joined to exchange2000 admin group The backend -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fyodorov, Andrey FTL Sent: September 17, 2004 4:35 PM To: Exchange Discussions Subject: RE: exchange2003 non-delivery after joined to exchange2000 admin group Which server is responsible for sending mail to the Internet? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Theo Odartei Sent: Friday, September 17, 2004 4:34 PM To: Exchange Discussions Subject: RE: exchange2003 non-delivery after joined to exchange2000 admin group One front-end and one back-end.

I went through it but couldn't find anything. If anything it will be on the exchange side because the problem originated from another user. We are on exchange 2003. The only thing that has changed is that I run the exchange 2003 security policy on the GPO and moved the server to the new GPO. I will go through the policy but you would think if anything it should be global. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fyodorov, Andrey FTL Sent: September 17, 2004 3:19 PM To: Exchange Discussions Subject: RE: exchange2003 non-delivery after joined to exchange2000 admin group Is your e-mail program (Outlook Express or Outlook) configured to use SMTP authentication for outgoing e-mail? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Theo Odartei Sent: Friday, September 17, 2004 3:15 PM To: Exchange Discussions Subject: RE: exchange2003 non-delivery after joined to exchange2000 admin group The moment I removed it, I went back to the original message of " You do not have permission to send to this recipient.

Take them out. By putting a domain name into YOUR recipient policy you declare that YOUR server is responsible for that domain.
