Something I'd be interested in is why your boss "direct[ed]" you to SendMail.pm. Does he know of particular features of that package that make it superior to the ones available on CPAN? Or was it the first one he heard of?

Note that a significant bonus of using Net::SMTP is that it is a well-known and widely used package, and thus carries a strong presumption of having gone through a battle-tested QA process. Of course, that a module is on CPAN is no *guarantee* of its high quality, but Net::SMTP is one of the modules that has a good pedigree and is widely used.

That said, it's probably worth taking a look at SendMail.pm and running it through, say, Dominus' "repair shop/ red flag" process (see his home node for more; here is a link to one of the articles he wrote for perl.com) to get a handle on the quality of the code.

HTH.

I mistrust all systematizers and avoid them. The will to a system shows a lack of integrity
