[Mimedefang] Setting variables

[Jim McCullars]

Hi, I have a question about setting variables in mimedefang-filter.  If I
set a global variable in, say, filter_relay, will it be there in all other
routines?  Or if I set it at the beginning (just under $Stupidity in the
example), will it be there for all of them?  I'd like to set a global
variable $LocalRelay one time and have it available in a couple of places.
