Sorry to hear about your problem.
In the example you show below, there's a sequence of HTML text,

Lots of spammers encode their messages to avoid being detected by
simple text string matches.
Per the docu
Hi,

full SYMBOLIC_TEST_NAME /pattern/modifiers
Define a full-body pattern test. "pattern" is a Perl regular
