Directory Harvesting Attack Prevention
A Directory Harvest Attack is a method spammers use to determine valid email addresses at your domain and add those to a database to send future spam. Reflexion provides its customers the capability to prevent such attacks, which can number in the thousands, outside of your network and protect the corporate mail server from latency or backlogged queues. RTC has the capability to deny delivery and send a non-delivery receipt, or to simply vaporize the message so the spammer doesn't know which address is legitimate and which is not.
