Hi,

Do the external senders recieve and NDR? Do you have your MX records setup correctly? Are you using an edge server? Do your MX records point to your external FW IP and then the FW forwards mail to your hub transport server? We really need more info.

ok my dns is hosted with att only my internal do i control.  we had a big problem today that OWA for exchange 2007 was not working from the outside.  that got fixed by the firewall people and now we cannot receive mail from teh outside.  we can send fine.  what should i do??

If somethings been changed on your FW I would be checking that first. Are you able to telnet to port 25 on the external IP that your MX record points to?

Try putting your SMTP domain in here: -
