postfix：在國內發給自己正常，在國外發給自己就報錯
postfix一個非常奇怪的問題：
基於postfix的郵件系統，在國內收、發、轉發和發給自己都沒有問題；
但是在國外可以收郵件、發送給其他人，不過發給自己就報錯。
maillog中也沒有抓到相關的報錯信息，在國外的outlook上測試，返回的錯誤信息為：
"send test email message: Unable to send test message, please verify the Email address field.「
經檢查發現E-mail Address欄位正常
真是非常奇怪。
請高手指點！！

《解決方案》
請檢查DNS解釋或者說是不是IP地址給加入一些黑名單！
《解決方案》
確認不是IP或DNS被列入了黑名單
原因尚不清楚
