I was about to say the same thing, as Net::SMTP is a core module, I usually prefer to use core modules, if it provides the functionality I want.

But as you said it already, I gained more time to look into the Mail:: stuff, source code and document, and think about those a little bit more.

Hey, I do like it. The Mail::Mailer and other supporting classes are done in a “real” OO-style. They had all the entities abstracted, for example, they have this Mail::Address class to wrap RFC822 mail addresses. That’s what the OO-style codes are supposed to look like, at least in theory. The design is neat.

I am not saying Net::SMTP is bad, on the contrary, for myself I would still use Net::SMTP, as it is slim.
