TippingPoint Advanced
Threat Protection for Email
maintains a routing table based on domains and email addresses.
TippingPoint Advanced
Threat Protection for Email uses this routing table
to route email messages (with matching recipient domains or email addresses) to
specified destination servers or to destination servers that match specified mail
exchanger records (MX records).
There are two message delivery methods:
-
Look up MX record
When delivering an email message using MX record lookup, TippingPoint Advanced
Threat Protection for Email queries the
specified MX record, and then delivers the email message to the destination
server identified by the MX record.
-
Specify servers
When delivering an email message using specified servers, TippingPoint Advanced
Threat Protection for Email first sends the
email message to the destination server with the highest priority. If the server
is unavailable, TippingPoint Advanced
Threat Protection for Email
chooses the remaining servers in descending order of their priority. If multiple
destination servers have the same priority, TippingPoint Advanced
Threat Protection for Email randomly
selects a server for message delivery.
Email messages destined to unspecified domains and email addresses are routed based
on the records in the Domain Name Server (DNS). For example, if the delivery domain
includes example.com
and the associated SMTP server is 10.10.10.10 on port 25, then all email messages sent to example.com
deliver to the SMTP server at 10.10.10.10 using port 25.
