出现类似553 can't verify FROM domain in DNS或者domain does not exist等等退信,一般都是你的域名的DNS不稳定造成的,就目前的DNS来说,新网,万网时不时的出现抽风的现象,如果你的域名用的新网或者万网的DNS,一旦抽风,就可能导致邮件给对方拒收。
在对方接收邮件的时候,都会对SMTP对话中的MAIL FROM的域名进行反向验证,查看是否有MX记录等,同时也会对邮件头的From信息进行验证,看看邮件上显示的From是不是一个有效的域名。为了你的邮件收发的稳定性,可以使用DNSPOD或者DNS盾等来解释你的域名。
下面是其它常见的这个类型的错误:
***@hkstar.com, 553 zeng.pionmi.com does not exist
***@se.abb.com , remote server said: 550-Verification failed for jqh@bpeg.cn
550-It appears that the DNS operator for bpeg.cn
550-has installed an invalid MX record with an IP address
550-instead of a domain name on the right hand side.
550 Sender verify failed
554 refused, the sender's domain MX does not exist
