SOT - Mimecast, blacklist

Sorry to post OT, but anyone having issues with mimecast?

I normally send via my providers mail server (Specturm aka TimeWarner). Email to certain address never arrived, no bounce.

Setup to send to their domain and/or IP via their published MX and immediately got "451 - IP temporarily blacklisted". So far no response to my support query to them.
