IronPort Anti-Spam is tuned to deliver industry-leading efficacy world-wide. In
addition to locale-specific content-aware threat detection techniques, you can
further optimize anti-spam scanning for specific regions using regional rules
profiles. The anti-spam engine includes a regional rules profile. The regional rules
profile targets spam on a regional basis. For example, China and Taiwan receive
a high percentage of spam in traditional or modern Chinese. The Chinese regional
rules are optimized for this type of spam. IronPort strongly recommends you use
the Chinese regional rules profile if you receive mail primarily for mainland
China, Taiwan, and Hong Kong. You can enable the regional rules profile from
Security Services > IronPort Anti-Spam.

Note
Because the regional rules profile optimizes the anti-spam engine for a
particular region, it can reduce capture rates for other types of spam.
Therefore, IronPort recommends you enable this feature only if you
receive the bulk of your email from the specified region.
