From my perspective, SSL mail is relatively recent, and still is not default in most mail setups. Also, I just handed you the link, containing the script. All you need to do, is change the MIME::Lite::TT::HTML; object to a simple MIME::Lite object..... it is not that complicated. Thats probably why there is no package for it.... the code is available for you to use as a simple script.

I don't mean to offend, but this is a site for perl programming...... it's not the Tech Support dungeon in the basement of your corporation. So, if you can't figure out enough to swap the MIME objects, then hire a programmer. Google for "perl MIME::Lite attachment" and see all the code that has been written for free, for you to learn from.
