these partners for signature updates every 15 minutes and incorporates new variants into
FOPE filters accordingly.
INSIDE OUT Three times the protection
Most organizations incorporate anti-virus and anti-spam filters, but most use only a
single reputable solution provider. There are two important things to note with regards
to FOPE multi-layer filtering. First, you get three times the protection. All email
protection service providers react in a responsive manner and need to take time to develop
and update their signature files in response to new variants. Having three providers
gives FOPE the most effective and quickest turnaround time to respond to new variants.
Secondly, it is the security partners who are providing the filters. That is their core
competency, and Microsoft simply leverages and implements that into FOPE.
Spam mail affects users' productivity and consumes unnecessary network resources. Left
unchecked, spam can easily make email systems unusable. FOPE uses all the industry spam
detection methods, including the following:
● Internet Protocol (IP) and IP subnet reputation
● Connection analysis for suspicious or non-RFC compliant attempts
● Content analysis
● NDR backscatter prevention
● Customer reporting
● Industry spam lookup blacklists
● Directory-based blocking
These are just some of the more common and well-known methods. FOPE utilizes other
methods to fight spam as well, but we will not examine every method and detail because
these are covered in the FOPE Service Description and at TechNet. The important thing to
note is that your organization does not have to maintain spam protection nor compromise
on spam protection by using FOPE. Your organization will benefit from not having to
manage and tweak every spam control method. This takes away the busy work so your email
and network administrators can focus on more important tasks.
