Why is my IP blacklisted if I don’t use it as for outgoing email server purposes?
Your host IP was not really blacklisted because our blacklist code is 127.0.0.2 and your IP was just flagged as 127.0.0.4, that means “probably no outgoing mail server running here”. This flag code is used by our customers to feed preventive security mail systems. The DNSBL technology is used only by unauthenticated SMTP transactions, that is not your case for sure. So no harm to you.
