Hi Tom, I don't know how dynip does it, but TZO automatically creates a MX record for the domain you host through them. HTH, Tom -----Original Message----- From: Tom Rogers [mailto:trogers@xxxxxxxxxxxxxxxxxx] Sent: Thursday, September 16, 2004 2:17 PM To: [ISAserver.org Discussion List] Subject: [isalist] Hosting Your Own SMTP Mail on Exchange 2000 (Off Topic?) http://www.ISAserver.org We currently have a "catch-all" email alias with our ISP. We use Exchange/Pop3 v5.x to go out to our ISP and download all our email into our Exchange 2000 server. Exchange then routes the email properly. The ISP is now doing away with the "catch-all" email alias because of SPAM. So now I would like to host my own SMTP mail with our internal Exchange 2000 server. Can anyone point me to any articles on setting this up, especially since my Exchange 2000 Server sits behind an ISA 2000 Server. I would need to filter messages (spam) and have delivery rules (route emails per conditions) setup as well. I have a cable modem connection to the Internet, we have a registered domain name (which is NOT the same as out internal Active Directory domain name), we have a dynamic IP addr (but use Dynip - like TZO, as Dynamic DNS service). I need to know about the MX record and who would host that for me (would Dynip?), and how to setup ISA server 2000 to relay SMTP (or do I publish my Exchange Server?)
