Chapter 5. Using mail file rules to prevent spam
73
If a user established a rule that was too broad, for example, that user would
undoubtedly receive e-mail that was incorrectly categorized as suspicious. On
discovery of false positives, the user must make adjustments to the mail file rules
to avoid such invalid categorizations in the future.
Similarly, if a user was receiving uncategorized (regular inbox) e-mail that
appeared to be spam, those e-mail messages should be reviewed for
characteristics that might be used to categorize them as spam so that they are
deleted or placed in the suspicious folder in the future.
Denying mail from certain addresses
Some spammers use certain e-mail addresses from which to send their spam,
and sometimes they send mail from domains which the organization or individual
may not want to block entirely. For example, some spammers use public domain
e-mail sites to create and send their spam. A lot of times these spammers
change addresses frequently, but sometimes they use the same addresses
repeatedly. To deny mail from these addresses you can create a mail file rule that
denies mail based on the sender.
