So this is the second or third time that @Mike Edge has had to request an unblacklist of our domain. Apparently, emails with spam content have been going out. "Amaury, John Doe replied to a thread you are watching at KH-Flare. [Spam content." Any ideas on how we can combat this would be highly appreciated. Although I don't understand how emails like that are going out. People shouldn't be watching spammers' threads. We have been getting regular spammers, but we deal with them ASAP. A common spammer appears to be from X4facts(dot)com.
