DCC Trusted and Blocked List
You can create exceptions to DCC’s bulk classifications by using the Trusted and Blocked List. In
many cases, it may be easier to specify such exceptions using Pattern Based Message Filters, in
which case the mail bypasses both DCC and STA.
Note: In most cases, use the Pattern Based Message Filter menu for creating exceptions.
The DCC trusted and blocked list feature is useful for removing legitimate bulk mail, such
as mailing lists, from consideration as bulk while letting it be scanned by STA for spam
characteristics.
