BTW: s/was/is/ - it's still there ;-)

Exactly. It doesn't hurt, but it's not needed. (Not only in the Reply-To 
check.)

The only place where - has a special meaning in regexes is inside square 
brackets like   [a-f]   which matches the letters a, b, c, d, e and f. 
To make it more interesting, you can't escape - inside []. Instead you 
have to add it at the beginning or the end if you want to match a - 
inside [], for example [a-f-] or [-a-f] will match a, b, c, d, e, f 
and - (using [a-f\-] would also allow a \).

close to my keyboard... how did you call it? Mouse? :-)
