Dynamic Reputation leverages Proofpoint's machine-learning driven content classification system to determine which IPs may be compromised to send spam (i.e. part of a botnet). The purpose of IP reputation is to delay or block IPs identified as being part of a botnet or under the control of spammers. We do not intend to delay or block legitimate email that our customers are expecting. For more information, please read our Frequently Asked Questions | よくあるご質問(日本語).
