SMTP

[boab1965]

I'm looking at moving our exchange server from collecting mail thru a pop3 connector to using SMTP.

Do I need to point A record at the asme IP address as the MX records?

I was hoping to point the MX record to our IP address and have a hosting company do the web site.

Is there anything else I should watch out for when moving to SMTP?

Thanks

Robert

A record? Only if you want to do OWA.
MX / separate hosting? Then don't point the A record to Exchange.
Moving to SMTP? Make sure your Exchange server is up to date / patched / behind a firewall.

Also, for added benefit, behind a edge server using Forefront or some other SPAM/Virus filtering appliance that has a hardened OS (ie... Barracuda, Symantec, etc...) pointing your mx to it and having the "box" relay the clean mail stream to your Exchange server(s).

Actually, the MX record just points to an A record. The A record points to the public IP address.

The reverse DNS should point to the same name that's in the MX record. You'll get the best results that way.

I agree with cajuntank - put an Edge Transport server running Forefront in the perimiter network. Edgesync it to your HT that is also running Forefront.
