我对新服务器管理员以及 nginx 很熟悉,但除了通过 iPhone 访问我的邮件之外,其他一切都很好?
我已将域名更改为“domain.com”
问题是我可以通过我的外发 IMAP 服务器发送邮件,但无法连接到接收服务器?我只收到消息"the mail server at mail.domain.com is not responding"

我还向服务器发送了邮件进行测试,并收到了此错误,这有帮助吗?
Technical details of temporary failure:
[mail.domain.com. (10): Connection refused]
我还查看了 /var/log/mail.log,它有多个条目:
postfix/smtpd[12239]: connect from 5acefc9a.bb.sky.com[90.206.252.xxx]
Mar 23 06:47:09 new-domain postfix/smtpd[12239]: lost connection after CONNECT from 5acefc9a.bb.sky.com[90.206.252.154]
注意新域名这是不正确的,但配置中的服务器主机名和主机名是正确的?我最近移动了服务器,主机已将服务上的主域设置为 new-domain.com,所以这可能是问题所在?
就像我说的,它可以连接到发送服务器,但接收服务器却出现无响应错误?任何想法都将不胜感激!
答案1
“通过我的 iPhone 访问我的邮件”是指在客户端接收邮件吗?这通常使用 POP3 或 IMAP,而不是 SMTP,而且 Postfix 不是 POP3 或 IMAP 服务器。您需要类似多夫科特为客户提供POP3或IMAP访问。
