Can someone please help me resolve the following issue:
I am getting the following spam block message from my sbs server 2003 when I send an email to an address using a particular ISP:
Wed 2012-12-26 11:56:10: <-- 550 5.7.1 Mail from 220.127.116.11 blocked using Trend Micro RBL+. Please see http://www.mail-abuse.com/cgi-bin/lookup?ip_address=18.104.22.168
Their response to get over this is as follows:
Add the rDNS of this IP to clearly indicate static.
ex: mail.mail-abuse.com (O)
They suggest that I need to specify in my DNS settings that I have a static IP address and to use the script above
I have no idea what to do to get this resolved
