Blat - A Windows (32 & 64 bit) command line SMTP mailer. Use it to automatically eMail logs, the contents of a html FORM, or whatever else you need to send。 没错，这个就是这个开源小工具的开发者(blatman, mussont)在sourceforge.net发布的时候的描述。
下载链接(包括了可执行文件和源代码)：
Sourceforge: http://sourceforge.net/projects/blat/?source=navbar
简单使用方法：
在控制台中切换到Blat.exe V2.6.2文件所在地址（仅需Blat.exe文件）；
配置Blat的SMTP服务器：
blat -install sever usr try port [profile]
163邮箱举例：
blat -install smtp.163.com user@163.com 3 25
其中的smtp.163.com是163的smtp服务器地址；user@163.com是自己的邮箱名，3是指尝试发送的次数，25是端口号；
[profile]指的是这个配置文件的名称，可以不填，也可以自己用一个名字，等到发送邮件的时候，就可以使用-p选项来指定配置，如果同时使用多个邮箱的话，这个就很方便了。
发送邮件：
blat C:/mail.txt -to demo@demo.com -attach "C:/fujia.txt" -s "zhuti" -u user@163.com -pw password -charset Gb2312
其中的mail是写好的邮件文件（邮件正文，已文件方式保存），-to demo@demo.com是收件人的地址，-attach "C:/fujia.txt"是附件地址，-s "zhuti"主题，-u user@163.com登陆服务器的用户名，-pw password密码， -charset Gb2312是中文编码
显示信息：
Blat v2.6.2 w/GSS encryption (build : Feb 25 2007 12:06:19)
Sending C:/mail.txt to demo@demo.com
Subject: zhuti
Login name is user@163.com
Attached binary file: C:/fujia.txt
如果只是以上信息，而没有错误提示，那么邮件就发送成功了。

If both -f and -i options are omitted then the RFC 821 MAIL FROM statement will be defaulted to use the installation-defined default sender address.
