Re: Using SBS Exchange as a public mail server

Tech-Archive recommends: Speed Up your PC by fixing your registry

See http://msmvps.com/blogs/javier/archive/2004/10/25/16621.aspx and post
back if you have questions about how to configure the DNS.

A Smarthost is where, instead of just sending your outgoing e-mail using
DNS, you send it through an SMTP server at your ISP. This can help avoid
issues where your outgoing mail gets blacklisted because you have a
DHCP-assigned IP address, your SPF is configured incorrectly, or some other
issue.

See the link above for more info about doing DNS with a dynamic IP.

What exactly are A plus PTR records and what IP or name should they
'point' to?
We have one public IP address the Cisco PIX is using as its outside
interface. Is this the address the DNS records point to? Also, what is a
smart host? Does it involve DDNS services?

Run the Internet Connection wizard on the SBS box and tell it to deal
with
mail directly via DNS.

Be aware this part only works if you have a static public IP address AND
A plus PTR records are properly setup in the public DNS. If you have a
dynamic public IP address, you will need to forward outgoing mail to a
Smarthost.
