You're referring to $myclass::Sender. A possible solution is what
Steffen suggests: explicitly write $::Sender or $main::Sender.

Another possibility is to look at the modularized mimedefang-filter
that I've developed, which allows you to selectively "import" the
mimedefang variables in your own package. It's at:

http://www.xs4all.nl/~johnpc/mimedefang-modular/

You'd use it like:

    package myclass;
    use Mimedefang '$Sender';

    sub test1 {
	print "$Sender\n";
    }


PS, helpful hint: do not use function prototypes (the brackets after
"sub SUBNAME"), they're useless (and ignored) for object-oriented
programming and deprecated for every other purpose.
