Blocking by content
3
In the subject line box, type the subject lines (one per line) that Symantec
Mail Security for SMTP should block.
You can use the * and ? wildcard characters. The * wildcard character
matches 0 or more of any character. The ? wildcard character blocks any 1
(exactly 1) character.
For example, *hot* would block any subject line that contains those three
letters consecutively in the line (For example, any line that contains the
word shotgun would be blocked.) The wildcard string ?hot? would block the
subject line shots, but not hot, hots, or a line that contains any of those
words.
(Using the ? wildcard character to match a high ASCII character does not
result in a block.)
Subject-line blocking is not case-sensitive. Fw: and Re: are added
automatically by the software.

Under Take the following action when a subject line violation occurs, select
one of the following:
■
Drop message
■
Log only
■
Forward message
5
If you selected Forward message, in the To email address box, type one
address to which the blocked message will be forwarded, and then, in the
Subject line box, type the subject line of the rejected message to be
forwarded.
