What you do is you have the DNS set up so that the MX record points to the new gateway server, instead of the existing server. For example, if you now have: example.com. MX 10 mail.example.com. mail.example.com. A 127.0.0.2 You would change it to: example.com. MX 10 gateway.example.com. mail.example.com. A 127.0.0.2 gateway.example.com A 127.0.0.3 That way, all mail will go to the gateway server. The gateway server then scans the mail, and sends it to the existing mailserver. By keeping the existing "mail.example.com" A record, people with mail clients set to connect to "mail.example.com" will still connect to the existing mailserver, so they can get their mail. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] This E-mail came from the Declude.Virus mailing list.
