Okay, please excuse my thick-headedness.

So the "^" means that the expression must commence at the beginning of a 
new line.

So the "$" indicates that the end of the expression is also the end of the 
line?

What would cause the following to work sporadically?

/Offending String/ REJECT  (in body_checks.regexp)

It seems that it depends on whether the offending string is in an 
attachment or not.  Must I do something different to look for an offending 
string inside an attachment?
