CNAME lookup failed temporarily. (#4.4.3) I'm not going to try again; this message has been in the queue too long

| 错误代码 | CNAME lookup failed temporarily. (#4.4.3) I'm not going to try again; this message has been in the queue too long. |
| 形成原因 | CNAME查找暂时失败。(# 4.4.3) 我不打算再试一次,这条信息已经队列太长。 |
| 解决办法/流程 | 该问题是域名解析的问题，并非邮件服务器的问题。
收件方域名的CNAME记录无法被发件方的DNS服务器成功解析，重复查询失败导致对方放弃尝试，直接退信。
建议：
1. 联系 收信方域名提供商查询该域名在发件方DNS服务器上解析的情况
2. 请发件方重新刷新一下他们的DNS服务器，或者对 收信方域名做定向解析后进行重试。 |
