Frequently Asked Questions
SPAM Detection and Handling
1. How does BreņaMail determine which messages are spam?
BreņaMail employs an extensive range of tests on incoming
messages to detect spam. These include
traditional, widely used approaches for spam detection such
as message authenticity checks, header
analysis, message signature analysis, an artificial
intelligence Bayesian engine, databases of domain
names and addresses used by spammers, and whitelists and
blacklists. BreņaMail has also developed
advanced, industry-leading techniques such as real-time
message source analysis, graphics analysis,
and user-based message profiling.
2. What happens to messages that
are detected as spam? You have several
options for handling the spam messages detected by
BreņaMail. Junk messages can
be 1) redirected
to a BreņaMail-hosted quarantine, 2) redirected to an
alternative email address such
as spam@yourcompany.com,
3) identified as spam in the subject line and delivered to
the intended
recipient, or 4)
deleted. These options can be configured company-wide or on
a per-user basis, and
can be changed at
any time.
3. What percentage of junk email does BreņaMail catch?
The detection rate varies by customer and is based on the
email traffic patterns for a given domain,
and on BreņaMail’s aggressiveness for that domain (customers
can configure how aggressive the filter should be). On
average, BreņaMail blocks over 98% of junk email and 100% of
email-borne viruses.
4. What are whitelists and blacklists?
Whitelists are rules that allow messages to be delivered
based on their 'from' email address or domain name,
regardless of content. If you would like to guarantee that
all messages from yourcustomer.com,
for example, will not be flagged as spam regardless of what
those messages contain, you can simply
add that domain to your whitelist. Conversely, blacklists
are rules that block messages based on the domain name or
email address of the sender. |
