Please help, I've installed new server CentOS 7, MailScanner 4.85.2, ClamAV, postfix, SpamAssassin. Some of my colleagues start to receive messages with text: "MailScanner was attacked by a Denial Of Service attack, and has therefore deleted this part of the message." In log file I've got: "MailScanner: Content Checks: Detected and have disarmed KILLED tags in HTML message" In "Removing dangerous content" section I've trued to switch of (setting to yes) , one by one, sections like IFrame, From, Script and etc. But nothing happens. I hope you know how to fix it.
