No, that is precisely what does NOT happen. The director is not run if
the suffix does not match. That's what I said before. It is purely a
textual matching process. The validity of what is left as the local part
is not checkable at this time.

Is it worth it? How often does this problem arise in practice? [As it
happens, I have re-organized that code recently, for other reasons, so a
straight patch won't work in the next release.]
(I hope you aren't now also going to suggest a change to regular
expression matching in PCRE to go for the longest possible match... :-)
