We moved our email server to another location in our company, and it got a new IP address. Our internet connection remains in the same location.
When the move occurred, I altered the existing PIX rules to account for the IP address change and modified the static NAT entry so that it would send to the new IP address but now our outside relay can no longer connect to the inside email server and we are not getting our external email.
Internal email works great as does outbound email.
I verified that the PIX in question can ping the email server at the new address.
I don't know what to try next. Please help!
