Track Specify whether VStream Antispam should log spam, by selecting one of
the following:
• Log. VStream Antispam should log spam.
•
None. VStream Antispam should not log spam.

matches or exceeds this threshold, the email is considered spam.
Setting a higher SCL reduces the number of legitimate emails erroneously

Enabling/Disabling VStream Antispam on page 531.
