Config File Questions

[Tim Miller <Tmiller @ nethawk . com>]

I have a few questions in regards to the 'taboo headers & taboo body'
section of the config file.  I have read what documentation I have on this
and have not seen the answers (perhaps I've overlooked it).

I have been told that every entry in the taboo sections must have the
character '/' at the start and end of the string you are looking for (like
below).  Is that true and if so why?

/badword/

I am also told that email addresses must be formatted like the below
example.  Again, if this is true, why?

/address\@nowhere.net/

Thanks in advance.
