设置新服务器，但遇到了一些 postfix 问题。使用与我拥有的另一台服务器相同的配置进行设置，运行良好。
无论如何，当我尝试发送到某个域名时，我总是收到
Feb 14 10:28:55 web postfix/smtp[6276]: B9056A041A: to=<[email protected]>, relay=mailserver.innovative-payroll.com[213.171.216.114]:25, delay=0.29, delays=0.06/0.01/0.01/0.21, dsn=5.0.0, status=bounced (host mailserver.innovative-payroll.com[213.171.216.114] said: 550 <[email protected]>: Sender address rejected: Domain not found (in reply to MAIL FROM command))
innovative-payroll.com 域名的 MX 记录似乎设置正确
在域上使用 dig 我得到以下内容。
; <<>> DiG 9.6-ESV-R4-P3 <<>> mailserver.innovative-payroll.com

编辑文件 /etc/mailname 并将其设置为服务器的域 (hoodoowebdesign.co.uk)，现在它可以正确发送。我假设它已经自动填充了
kickseed.vpstest.local
当我使用其中一个快捷方式在服务器上安装 LAMP 环境时。
答案1
确保您的机器配置为响应主机名 web.hoodoowebdesign.co.uk，并确保主机名在 DNS 中正确配置。显然，主机名目前有所不同，因此来自您的邮件最终来自 kickseed.vpstest.local。
