After much research, I've found some interesting tidbits. Out of the 88 blacklists mxtoolbox reports against, 6/7 relays reported 3 problems - 1) Efnet blocks Tor exits and reported. No exceptions. - 2) CBL detected a single trojan/malware/spam, etc, and reported - 3) Spamhaus ZEN detected CBL's detection, and reported 1 of the 7 relays also had two hits from Mailspike - 1) Mailspike Z found a distributed spam wave, and reported - 2) Mailspike BL aggregates other Mailspike lists, and reported Essentially, all 7 of my relays were taken down because of trivial issues, all but 1 being single instances of reported problems from a single source. Both CBL and Mailspike offer de-listing services that are easy to use, and straight forward. I spoke with MasterCard yesterday, and they've mailed off the paperwork I need to fill out to do the charge-back. I won't get into the specifics, but they were encouraging. I will also be moving my unrelated business dealings away from OVH as soon as possible. Speak Freely
