[Business] Comcast SMTP server is blacklisted

This is just an FYI post if you are getting undeliverable emails via smtp.hmc1.comcast.net - Apparently at least one of their servers (76.96.53.6 - omta01.westchester.pa.hmc1.comcast.net) has found its way onto some blacklists. First it was on blacklist.lashback.com - That got fixed, and now it's on 4 more:

»mxtoolbox.com/SuperTool. ··· toolpage

Comcast knows about it, but it's taking some time to fix...
