exchange 2016 邮件传递延迟

您好

 向国外的邮件服务器传递邮件延迟，返回下列信息：

test@contoso.com
Remote Server at ex01.contsoso.com (192.168.10.3) returned '400 4.4.7 Message delayed'
2021/01/12 06:00:11 - Remote Server at ex01.contsoso.com (192.168.10.3) returned '451 4.4.0 Primary target IP address responded with: "454 4.7.0 Temporary authentication failure." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint attempted was 192.168.10.3:2525'

其中contoso.com是目的端接受域名，源端域名是wiki.com，以上报错是源端用户收到的邮件提示，这种情况下该如何分析。
