Call Toll Free 800-793-1947  

Purespeed makes every attempt to ensure that our customers can trust the email that they receive is from a valid source.  Just as paper mail is unauthenticated, so is email.  However, there are certain techniques that can be performed to minimize the amount of email that is spoofed or send from untrusted sources.  Purespeed applies the follows mail policies to all incoming email. 

1) Per RFC 821, http://www.ietf.org/rfc/rfc0821.txt, mail servers are required to send a HELO message prior to exchanging email.  The HELO message sent by the sending mail server must use a valid domain name.  The following documentation describes how this policy is implemented: http://www.postfix.org/uce.html#smtpd_helo_restrictions

 2) When receiving a message, the mail must be sent from a sender with a valid return address.  Email without a valid return address will be rejected per http://www.postfix.org/uce.html#smtpd_sender_restrictions

 3) Mail servers that are identified as "open relays" by ORDB, http://www.ordb.org, will not be permitted to send mail to our customers as they are targets for spam relay.
