Scott Perry Sent: Tuesday, October 22, 2002 1:55 PM To: [EMAIL PROTECTED] Subject: RE: [Declude.JunkMail] Exchange going though ISA Proxy fails HELO test The first step is to see what is wrong -- checking the log file or X-RBL-Warning: header will give you details of exactly what the problem is. The problem is that the machine is using a made-up name, such as "nonexistenthost.example.com", that just doesn't exist on the Internet. It needs to have an A record in DNS. That's all. -Scott At 02:44 PM 10/22/2002, you wrote: >I got in touch with the ISP and it looks like they their mail servers set up >like this: a public smtp server on the outside of the proxy and a private >mail server inside the proxy. > >The internal mail server was receiving the messages first (and has no >corresponding host record in the DNS), then sending the messages to the >public mail server to deliver to destination mail server.
