Hi, i did the SPAM test, and the result shown that i am blacklisted in the SORBS (http://www.sorbs.net/lookup.shtml). Is this system run by Proofpoint, Inc. creditable or just a gimmick to get us to sign up for their services?
Cause among all the other 24 most common IPv4 blacklists, only this SORBS is blacklisted... fishy? Can anyone from AcyMailing team advise about this? Will there be any consequences if ignore that black list?
