I took a look at what you have. Mostly, it looks good. The Domain Information dialog has good entries. However, you only have the following entries:
afg-flies.com. NS mach1.teck.net.
afg-flies.com. MX 10 mail.teck.net.
afg-flies.com. MX 20 mail2.teck.net.
www.afg-flies.com. A 209.73.79.132

Add the following:
afg-flies.com. NS mach2.teck.net.
afg-flies.com. A 209.73.79.132

The former indicates that you have a second DNS server. The latter permits a potential visitor to reach your server by typing "http://afg-flies.com" instead of having to include the "www.".

One other problem: mach2.teck.net does not have data for the zone. You should configure its Secondary Data window for this domain. It needs to know the name of the domain, a unique filename where it can store the domain data (the name of the domain is a good choice), and the IP address of the primary server.

Not sure why this is happening. The main MX record is correct, the name it points to resolves properly to an address, and that address' PTR record resolves back to the same name.

The error message indicates "sender domain must resolve" - this is a new one on me. Perhaps the A record for afg-flies.com will solve it. If that doesn't do it, try contacting someone at the domain in question (mediaphex.com) to ask how to avoid this problem. Their domain registration record indicates "domain@mediaphex.com" as their sole contact; their actual zone file indicates "bdavis@mediaphex.com" as the address of their hostmaster; you might also try "postmaster@mediaphex.com".
