1、通过SSL加密方式 https://gmail.google.com （首选）来登陆Gmail，可以防止黑客通过Sniffer等工具窃听用户名和密码。

2、移动版Gmail：http://m.gmail.com

3、Gmail的Feed地址为https://mail.google.com/mail/feed/atom

4、POP方式收发GMail邮件的重要参数：

“pop.gmail.com”

“smtp.gmail.com”

选中SSL

SMTP字段：465

POP3端口： 995

5、如果无法访问Google，那么请把下面这一行：

　　216.239.63.104 www.google.com　或者　64.233.171.99 www.google.cn　或者　216.239.53.99 google.com

　　添加到：C:\WINDOWS\system32\drivers\etc\hosts文件里，就着访问Google看看是否正常。（其原理是提供较为少用的Google镜像访问）

6、附录：Google的IP地址一览表：
