How can I
configure Exchange Server 2003 to block
spam?
Microsoft
Exchange Server 2003 now has built-in
Open Relay Filter (ORFilter) or DNS
Blacklist and Realtime Blackhole List
(DNSBL, RBL) capabilities, which
releases us from the need to rely on 3rd
party software for the spam filtering.

Intelligent Message Filter
Microsoft
Exchange Intelligent Message Filter
(IMF) was released at the end of May
2004.
Microsoft Exchange
Intelligent Message Filter is a product
developed by Microsoft to help companies
reduce the amount of unsolicited
commercial e-mail (UCE), or spam,
received by users.
Intelligent Message
Filter is based on Microsoft
SmartScreen Technology from
Microsoft Research. By using e-mail
characteristics tracked by
SmartScreen technology, Intelligent
Message Filter can help determine
whether each incoming e-mail message is
likely to be spam. Based on this
likelihood, you can choose to block
e-mail messages at the gateway or at the
mailbox store. |
