Skynet got blacklisted - Google mail servers entered RBL of Sorbs.net

When yesterday my client sent me the headers of blocked by eSafe (Aladdin) mails I was quite surprised - the message said " Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 574 574 MAIL REFUSED - IP (74.125.82.172) is in RBL black list recent.spam.dnsbl.sorbs.net (state 18). " What? Google servers got blacklisted ? No way .
I also expected Sorbs.net to be wiped out from the Earth rather quickly for such act of aggression against Skynet , also known as Google.com but nothing actually happened. So just for the fun of it I checked another IP of theirs - 74.125.82.48, also blocked. In short the class-C 74.125.82.0 got listed (screenshot follows). From practical point of view - make sure if your device is using www.Sorbs.net to put this pool in exclusion list, as I did in the eSafe of the client.
