我有一个laposte.net免费的法国电子邮件提供商的问题：自从几个星期以来，他们的smtp服务器不再接受空MAIL FROM 。 这是一个示例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.
我知道这是必须接受这些电子邮件，我已经多次与他们联系，没有任何运气。
对于我来说，问题在于邮递员邮件列表：由于邮件是用空MAIL FROM发送的，所以他们都被laposte.net地址拒绝（其他域名可以正常工作）。
你知道一个解决方法，无论是作为邮件configuration选项，或者可能使用Postfix特定的重写规则，以更改发送到此域的邮件的空MAIL FROM ？
编辑：这是Mailman（我的系统上的版本2.1.15）发送的邮件的完整标头：

看看Postfix的PCRE地图 。 它允许您定义基于正则expression式的地址重写邮件。
