我在 mail.ans.co52.com 设置了一个测试服务器,运行 Postfix 并使用正则表达式规范收件人映射:
在 /etc/postfix/recipient_canonical-正则表达式:
/[0-9]+@mail\.ans\.co52\.com/ catchall
直接发送电子邮件至[电子邮件保护]工作正常,但如果我发送邮件到[电子邮件保护]失败并显示以下日志消息:

答案1
它的意思是:
Dec 13 07:06:20 ans-www postfix/smtp[16803]: certificate verification failed for mail.ans.company52.com[205.186.183.147]:25: untrusted issuer /C=US/O=Equifax/OU=Equifax Secure Certificate Authority
您的证书无效(无论是什么原因造成的),但 Postfix 会推迟递送/发送。请修复它。
