RP Filter

RP Filter is an effective, low-cost email filtering service provided by Reliable Penguin. RP Filter stands between your email servers and the Internet, acting as a guardian to protects your users and infrastructure from email threats like spam, viruses and phishing attacks.

RP Filter evaluates each and every email message using the latest in scanning technology. If the message is deemed legitimate, it’s delivered to the recipient’s email inbox. If the message is deemed spam, the subject line is tagged, and a user-configurable header is added to the message for delivery by your existing mail server to the user’s inbox, or designated spam folder. You may also chose to have spam delivered to a web-based Spam Quarantine where the recipient can periodically log in to view messages flagged as spam. If a message contains a virus, it is simply discarded, protecting your users from infection.

RP Filter is:

  • Flexible – Can be used with your existing mail server or with your Reliable Penguin email service.
  • Easy to Deploy – An experienced engineer will guide you through the setup process.  Just add mail boxes and point your DNS record to RP Filter.
  • Affordable: At less then half the price of competing serivces, RP Filter is the affordable choice.

Prices start at just $1 per mailbox per month with no setup fee and no minimum number of mailboxes.
