Okay, I am need of some real assistance here. I requested removal from the CBL/Spamhaus blocklist on 7/26/2005. It appeared we were removed shortly after the request. However, I just went out and checked our Public IP/NAT against the website http://www.moensted.dk/ and it shows we are currently being blocked by the following lists: CBL XBL DNSBlaut1 Clue-all Nerd-ZZ We have shutdown port 25 for SMTP relays ... only our Exchange Server is allowed to send emails outside the firewall. So, what in the world could be causing our public IP/NAT to continue to be blocked by these lists? Any help is greatly appreciated. We are a non-profit family and childrens agency and the ability for us to email folks on the outside of the agency is very important. Many thanks for any recommendations/suggestions! Brian
