Pilot Run of Spam Detection Service for HKUST iMail User
In order to make it easier for our users to get rid of annoying spam messages,
ITSC has recently set up a pilot spam detection service using a heuristics-based
spam detection engine. All interested HKUST iMail users are welcome to
join the pilot run of this new Spam Detection Service.
Namely, a spam detection engine is employed that attempts to recognize
potential spam messages based on a set of heuristic rules. Suspected spam
messages would then be delivered to a special email folder (called AutoTrash)
of the recipient. These messages will be erased by the system automatically
after 30 days unless the user saves them to another folder.
There are a few points worth noting about this pilot service:
-
It will only be effective after explicitly turned on by the user. It can
be turned off at any time.
-
Only messages coming from outside would be checked. All internal
email messages (e.g. those sent via iMail or departmental email servers)
would not be affected.
-
To avoid missing legitimate messages that are mistaken as spam (so called
the false-positives), it is highly recommended that users should check
the content of the AutoTrash folder regularly. There are some ways (e.g.
tuning the proper sensitivity level, safe list, etc.) which can help cut
down the possibilities of false positives and users are advised to get
acquainted with them.
