使用 上的“我忘记了密码”按钮时/admin/users/login，所有发送到外部电子邮件地址的电子邮件都会失败。例如，如果用户有 的密码重置电子邮件，则me@internalDomain重置代码会顺利发送。但是，如果他们有 的密码重置电子邮件，则me@externalDomain它会失败。发送到外部域的所有其他类型的外发邮件均正常。
在邮件日志中，我看到发送普通邮件时，有一个发件人地址(<me@mydomain> -> <me@externalDomain>)。发送密码重置邮件时，发件人地址为空白(<> -> me@externalDomain)。
我们还使用 Dovecot、SendGrid 作为邮件中继，并使用 amavis 作为内容过滤器。由于发件人地址为空，SendGrid 的发件人授权拒绝了该电子邮件。有人知道如何设置密码重置的发件人地址吗？或者可能是什么设置错误导致仅在这种情况下发件人地址为空？

答案1
检查是否config.local.php $CONF['admin_email']设置了。postfixadmin 使用它作为发件人，不幸的是，如果没有设置，就无法回退到 postmaster 等。
根据 RFC 5322 第 3.6 节，发件人是两个必需的标题之一，因此这些邮件被正确拒绝。
