常用smtp\pop\imap及imap连接测试脚本

确认是否ssl方式连接很简单，
25端口（SMTP）：25端口为SMTP（Simple Mail Transfer Protocol，简单邮件传输协议）服务所开放的，是用于发送邮件。
465端口（SMTPS）：465端口是为SMTPS（SMTP-over-SSL）协议服务开放的，这是SMTP协议基于SSL安全协议之上的一种变种协议，它继承了SSL安全协议的非对称加密的高度安全可靠性，可防止邮件泄露。SMTPS和SMTP协议一样，也是用来发送邮件的，只是更安全些，防止邮件被黑客截取泄露，还可实现邮件发送者抗抵赖功能。防止发送者发送之后删除已发邮件，拒不承认发送过这样一份邮件。
