It's best not to use too many global variable.  (I know that's a funny
statement coming from the author of MIMEDefang, but hey... everyone makes
youthful mistakes...)

If you must use global variables, I recommend defining a function
like this:

use vars qw($GlobalVar1 $GlobalVar2); #etc

sub init_global_variables
	$GlobalVar1 = undef;
	$GlobalVar2 = undef;

Instead of "undef", use whatever initial value makes sense.  In fact,
MIMEDefang has an internal "init_globals" function that does something
like this.

Then be sure to call init_global_variables where appropriate.
