夹缝中求生存
前言：在上一篇随笔中，以163个人邮箱作为发送邮箱地址，当收件邮箱为QQ邮箱时，极有可能会被直接扔进邮件垃圾箱里，为了解决这个问题，申请注册企业邮箱，可以减少发出的邮件被当作垃圾邮件的可能性。本文以腾讯企业邮箱为例。
- 既然是企业邮箱，首先前提是你得有一个自己的域名。然后就可以去申请免费的腾讯企业邮箱账户，传送门。
- 按照免费腾讯企业邮箱的申请要求，验证域名所有权后在域名提供商处设置好MX解析。下图是我在阿里云的域名设置。
- 设置好网站邮箱管理员后，可添加一个成员账户，比如命名为service@xxx.com(xxx.com是你的域名)，该邮箱地址将作为对外发邮件的账户。
- 记得要确保设置好开启该邮箱的账户smtp服务，邮箱->客户端设置里设置。
- 下面就可以愉快的玩耍了。
