还在为Linux下没有便捷的邮件程序苦恼，还在为复杂的邮件服务器架设Google N多网页? 对于小型，便捷的Linux下命令行邮件程序，sendEmail使得这一切变得轻松可行。一起来看看吧。
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.
[Supported Platforms: Linux, BSD, OS X, Windows 98, Windows NT, Windows 2000, & Windows XP]
总的来说sendEmail简单，轻量级，命令行，可伸缩，跨平台。

2) Copy the sendEmail script to /usr/local/bin
cp -a sendEmail-v1.XX/sendEmail /usr/local/bin
3) Make sure its executable
chmod +x /usr/local/bin/sendEmail
4) Run it
sendEmail
or
/usr/local/bin/sendEmail

Reading message body from STDIN because the '-m' option was not used.
If you are manually typing in a message:
- First line must be received within 60 seconds.
- End manual input with a CTRL-D on its own line.
