我在我们的网络服务器上发送邮件时遇到问题。某些邮件的发送和发送没有任何问题(例如Gmail),而其他邮件则推迟了“发件人地址被拒绝:未找到域”
我了解这是一种垃圾邮件防护措施,可以在发送域上进行查找,但是我们的域具有MX记录:
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
premiumconnect.co.za mail exchanger = 10 za-smtp-2.mimecast.co.za.
premiumconnect.co.za mail exchanger = 10 za-smtp-1.mimecast.co.za.
Authoritative answers can be found from:
(顺便说一句,为什么我们没有权威的答案?可能是这个问题吗?)
以及A记录:
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
Name: premiumconnect.co.za
Address: 196.28.97.202
以下是尝试发送的特定邮件的日志:

我对Sendmail(或一般而言,MTA)经验不足,不确定其他信息是否有用。
