如題,我們公司的信箱發給自己公司的郵件或其它客戶都是正常的,但唯獨寄給Gmail信箱都會立馬退信,內容為:
mx.google.com
Remote Server returned '550-5.7.1 [118.163.78.210 7] Our system has detected that this message is 550-5.7.1 likely unsolicited mail. To reduce the amount of spam sent to Gmail, 550-5.7.1 this message has been blocked. Please visit 550-5.7.1 https://support.google.com/mail/?p=UnsolicitedMessageError 550 5.7.1 for more information. r3si10700716pga.554 - gsmtp'
我嘗試檢查有無被設黑名單,結果是沒有的。
該修正都修正了!!!
我不知道還有哪裡是我沒注意到的,煩請各位大神賜教感謝!
補充:公司的Mail Server是用Exchange server 2013架設的。
