I guess a big part of the problem is not perl-related.

First you have to setup your mail server correctly, for example ensure that it works properly if the receiving server uses gray listing, sender verification callout and the like.

And then make sure that your $subject and $body don't look like spam.

Why do the spam filter classify your mail as spam? because of the headers? Or because of bayes classification of the text?
