I seem to be having a problem with Blacklist and my Exchange Server. It seems that my emails being sent out to certain domains are being blocked because the Private IP of the exchange server is blacklisted. Here is my setup
Exchange 2003 server with a Private IP of 220.127.116.11
SonicWall NSA2400 Firewall with a Public IP of 173.25.38.xx
Message from Email Bounce Back
554 Service unavailable; Client host [mail.company.com] blocked using Barracuda Reputation; http://bbl.barracudacentral.com/q.cgi?ip=18.104.22.168
I have searched for an answer now for some time, but have no luck. Any help would be appreciated.
