如何解决这个问题？
如果您对设置有任何建议，请随时提出建设性的批评
最佳答案
返回的错误是由 Sender Address Verification 引起的。收件人服务器对发件人地址的 MX 记录执行回调以验证信封。邮件发件人地址 <<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ed8f8298838e88c6d8d4d8d8d9dbc3888fdbd5d8d8c082808c9fd0808c838c8a88809883c3829f8aad808ac3808c838c8a88809883c3829f8a" rel="noreferrer noopener nofollow">[email protected]</a>> .
在这种情况下，收件人服务器尝试回调“mg.managemun.org”，但由于子域没有 MX 记录而失败。因此，通过将 Mailgun 的 MX 记录添加到您的子域 mg.managemun.org，这些电子邮件服务器的 MX 查找将成功，并且服务器将接受您的邮件。 Mailgun的两条MX记录可以引用here :
Value : mxa.mailgun.org
Priority: 10
Value : mxb.mailgun.org
Priority: 10
