I have a person who is emailing to one of my clients (and me as well to test) from a citi.com (Citibank) email address. My server is blocking that address with the following bounceback to the user:

[my server IP] does not like recipient.
Remote host said: 550 Email blocked by SORBS - to unblock see
http://www.example.com/

the originating IP address is 192.193.219.200 and I checked Sorbs.net to confirm that they are not on their list.

I tried whitelisting through spam assassin the email sender's email address, but had the same results.

Any clue as to how to resolve this? I'm pretty sure Citi has reputable IP addresses . . . thanks for any help.
