一、sendEmail介绍
SendEmail is a lightweight, command line SMTP email client. If you have the need to send email from a command line, this
free program is perfect: simple to use and feature rich. It was designed to be used in bash scripts, batch files, Perl
programs and web sites, but is quite adaptable and will likely meet your requirements. SendEmail is written in Perl and is
unique in that it requires NO MODULES. It has an intuitive and flexible set of command-line options, making it very easy to
learn and use.
SendEmail is licensed under the GNU GPL, either version 2 of the License or (at your option) any later version.
