If this is as designed, then what is the best way to reset/undefine

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.
thanks for the recommendations, David.
