Not receiving email from yahoo, gmail, aol, pacbell.net, hotmail, etc...

Recently we upgraded from a Frame-relay T1 to a AT&T MIS T3. Our DIA service  (IP Block) was moved to this new router and the same exact routing statements were setup there as well. The configurations are exactly the same between the old router and the new. The only thin I changed on my PIX 515E was the new IP address and static routes. Our email leaves out of a Charter Cable Modem and incoming email is coming through the T3. The MX records did not change. There are PTR records for the cable modem and T3. I can telnet to our spam device on port 25.  The problem that i am having is that i get email from dell, att, charter, but noting from gmail, yahoo, hotmail, pacbell.net, etc...

You say the IP block was moved, then you say "was the new IP address " 

The bottom line is, the IP address that you MX references - did this change? If so, you need to update your MX record.

I think you may have given your domain in the question there, and I tried to connect to your MX and could not. smtp.citxxxxxx

a new static IP was given to us and we own a class C that is routed to our new router. the MX record resides in that class C. The only changed on teh network is the IP address of the internet connection from AT&T

You hav a Class C.

Ok, well xxxxx.cityxxxxx points to xx.xx.xx.11

That IP does not have port 25 open.

Either open port 25 on that IP or change to whatever IP you have configured for inbound mail.
