我们这里用的台湾邮箱,域名为repon.net,上网人少了就正常,人多了一点就断了,最近老是断掉.头都大了,也不知道那里出现问题.
我用上这个网www.dnsreport.com检测repon.net域名.出现一个错误提示
ERROR: One or more of your mailservers does not accept mail to postmaster@repon.net. Mailservers are required (RFC822 6.3, RFC1123 5.2.7, and RFC2821 4.5.1) to accept mail to postmaster.
repon.net's postmaster response: >>> RCPT TO:
<<< 550-"The recipient cannot be verified. Please check all recipients of this 550 message to verify they are valid."
不知道啥意思!
