The problem is that a use Net::SMTP; statetement is evaluated at compile time.
That means even if you write something like
if (0) {
use foo;
}
The compiler will try to load foo;
You can avoid it with using require:
if ($^O =~ /MSWin/i) {
...
require 'Net::SMTP';
Net::SMTP::import();
}
Require is evaluated at run time.
Note that the import call is necassary.

PS: BTW, it's better when the subject gives a short description of the problem.
Of course, you're asking What am I doing wrong ? because you posted in beginners.cgi.
