Email::Stuff, as its name suggests, is a fairly casual module used to email "stuff" to people using the most common methods. It is a high-level module designed for ease of use when doing a very specific common task, but implemented on top of the tight and correct Email:: modules. Email::Stuff is typically used to build emails and send them in a single statement, as seen in the synopsis. And it is certain only for use when creating and sending emails. As such, it contains no email parsing capability, and little to no modification support. To re-iterate, this is very much a module for those "slap it together and fire it off" situations, but that still has enough grunt behind the scenes to do things properly.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
