Release 3.0 is incompatible with Perl 5.8. Unable to locate v2.03 - appears to be removed from the Internet!!!
Module is missing any diagnostic output for when things go wrong. Rather than inheriting from Net::SMTP, this module creates a new (incompatible) subclass status to calling code.
A good point is that the module does not have as serious of the problems of the smtp_client.pl code it is based on.
