Well a normal allow for smtp would be something like this.<br />
<br />
permit tcp any host 10.10.110.1 eq smtp.<br />
<br />
You may just be impatient but you could try sending something to the server from a public email like hotmail or gmail as a test.<br />
<br />
Are you doing any NAT or is the public IP assinged directly to your mail server.<br />

I set an allow from any to my exchange servers public IP address with TCP/SMTP protocol on port 25, but I'm still not recieving email. I also just had the public DNS entry mail for mail,mydomain.com. Am I just too impatient?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
