我正在尝试使用 mailgun 设置入站邮件。我想通过 support@mydomain.com 接收电子邮件。(出于隐私原因更改)
match_recipient("support@mydomain.com")动作是forward("me@gmail.com")但是,当我在现实生活中向 support@mydomain.com 发送电子邮件时,我收到失败通知。错误信息是:
Your message cannot be delivered to the following recipients:
Recipient address: support@mydomain.com
Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;550 5.7.1 Relaying denied
Remote system: dns;mxb.mailgun.org (TCP|17.172.80.96|58312|52.5.239.85|25) (ak47 ESMTP ready)
Run Code Online (Sandbox Code Playgroud)
我在这里缺少哪一步?
