Hey everyone! I'm running ImprovMX.com, an email forwarding service and I'd appreciate your advice on a situation I can't find a solution for.
Some of my users are using Spamcop to notify them of spam abuse, which is good thing to do to fight spam. Unfortunately for us, Spamcop believe we are the one sending spam when they trace back the Received headers, because we are the last hop before landing to that user's inbox. Is there a way to tell in the headers that we are merely forwarding emails (we do have spam protection in place, but some of them always manage to get through) ? Or is there someone from Spamcop in this list I can discuss with about how to find a working solution? I thought about ARC, which would be a good solution to this, but ARC is useless (can't trust the signing domain) so it's out of the question. Thank you for your help! Best regards, Cyril
