MIME::Lite->send()
        When used as a classmethod, this can be used to specify a different default mechanism for sending message. The initial default is:
            MIME::Lite->send("sendmail", "/usr/lib/sendmail -t -oi -oem");
        However, you should consider the similar but smarter and taint-safe variant:
            MIME::Lite->send("sendmail");

        Or, for non-Unix users:
            MIME::Lite->send("smtp");
