Automatic Junk Mail Filtering at the University of Waterloo
Most mail servers at the University of Waterloo use a blacklist service to filter
incoming mail and reduce the amount of junk mail each user receives.*
You can exempt your userid from this, and receive every piece of mail
addressed to you.**
*It is impossible to remove all junk mail from the
incoming stream. Junk mail usually comes from a bogus address, and
often by way of an "open relay": a machine willing to deliver mail
from anyone, to anyone. Mail that is properly addressed and coming
from a legitimate address is always delivered.
**All mail addressed to your email@example.com
will be exempted from filtering, as well as mail addressed to your
userid on servers which subscribe to the exemption service.
You can filter mail yourself with your UNIX,
or Mac mail software. Cut down on the amount of junk mail you
receive by guarding your electronic identity, and
keeping yourself out of junk mailers' userid lists.
