夾縫中求生存

前言：在上一篇隨筆中，以163個人郵箱作為發送郵箱地址，當收件郵箱為QQ郵箱時，極有可能會被直接扔進郵件垃圾箱裏，為了解決這個問題，申請註冊企業郵箱，可以減少發出的郵件被當作垃圾郵件的可能性。本文以騰訊企業郵箱為例。

• 既然是企業郵箱，首先前提是你得有一個自己的域名。然後就可以去申請免費的騰訊企業郵箱賬戶，傳送門。
  
• 按照免費騰訊企業郵箱的申請要求，驗證域名所有權後在域名提供商處設置好MX解析。下圖是我在阿裏雲的域名設置。
• 設置好網站郵箱管理員後，可添加一個成員賬戶，比如命名為[email protected](xxx.com是你的域名)，該郵箱地址將作為對外發郵件的賬戶。
• 記得要確保設置好開啟該郵箱的賬戶smtp服務，郵箱->客戶端設置裏設置。
• 下面就可以愉快的玩耍了。
