bullet Fully automatic Backscatter (NDR) protection. Automatically kicks in when excessive NDR traffic is detected to any account.
bullet Our proprietary MXRate Sender Reputation Database. MXRate is a system that analyzes over 25 million spam messages daily to provide real time reporting to Alligate servers on the message sending habits of any particular sender.
bullet A unique implementation of a procedure called Greylisting. Our system avoids the typical pitfalls of other greylisting systems by only imposing greylisting if certain user defined criteria are met.
bullet Variable time "Tarpitting" is also employed to effectively discourage spammers and slow down attacks.
bullet Numerous verification systems allow flexible recipient checking, sender country testing, sender reputation lookup, DNSBL support, dictionary attack prevention, relay protection, authentication, "port 587" support, reverse DNS lookup and dozens of other techniques.
bullet Message/header progressive scanning system with user defined penalties and regular expression support.
