Remote Mail server is 93.42.237.19, and it seems they have blocked virginmedia's address block as a spam source, is it on a block list service somewhere? Error when sending email I know this is an old thread, but the same or similar thing seems to be happening again. I'm getting " 535 5.7.8 Error: blocked by Block Address check from 84.116.50.41" from a company I am trying to converse with's mail servr when I try and email them.
