We just moved from a NAT router (Cisco 2621) to a PIX 520 firewall. Now when we send email to EarthLink, we are being blocked with a:

 

"550 Dynamic IPs/open relays blocked. Contact <[EMAIL PROTECTED]>."

 

message in the logs.

 

The only difference that is known between the NAT and PIX configuration is that traffic used to be shown as coming from 199.44.118.253 using NAT. Under PIX iit is coming from 199.44.118.252.

 

Does anyone have any ideas? Is there a change to IMail I should have made?

 

Thanks.
