我遇到了 laposte.net 免费法国电子邮件提供商的问题：几个星期以来，他们的 smtp 服务器不再接受空邮件MAIL FROM。以下是示例 telnet 会话：
$ telnet smtpz4.laposte.net 25
Trying 194.117.213.1...
Connected to smtpz4.laposte.net.
Escape character is '^]'.
220 lpn-prd-vrin016 ESMTP Postfix (Ubuntu)
HELO XX.XXXXX.XXX
250 lpn-prd-vrin016
MAIL FROM:<>
501 5.0.1 Emetteur invalide. Invalid Sender. LPN007_403
421 4.7.0 lpn-prd-vrin016 Error: too many errors
Connection closed by foreign host.
我知道必须接受这些电子邮件，而且我已联系他们几次，但没有任何进展。
对我来说，问题在于邮递员邮件列表：由于邮件以空的形式发送MAIL FROM，因此所有地址均被拒绝laposte.net（其他域名工作正常）。
您是否知道一种解决方法，可以作为 Mailman 配置选项，或者使用 Postfix 特定的重写规则，将MAIL FROM发送到该域的邮件更改为空白？
编辑 ：这里是 Mailman（我的系统上是 2.1.15 版本）发送的邮件的完整标题：

看看Postfix 的 PCRE 映射。它允许您根据正则表达式定义来自地址重写的邮件。
