后缀:在中继邮件上重写收件人域

Question

我有一个邮件中继器(mx2.mycorp.com)，它接受somelist@lists.mycorp.com的邮件。这些帖子被转发到一个渐近邮件列表服务器，该服务器接受mycorp.com域的帖子。

这已经工作了相当一段时间，在一个较旧的版本的渐近和Ubuntu14.04，但问题是，这两个堆栈需要升级和废弃，在这两个软件部分已经破坏了大部分的设置。

我从Ubuntu18.04开始，但不太清楚如何让lists.mycorp.com的后缀传输用于中继到交收服务器，这样交感会会接受邮件列表的投递。现在，渐近服务器只是将投递转发到出口邮件服务器，因为它没有配置为接受“lists.mycorp.com(onlymycorp.com`”的邮件。这是出于虚荣心的原因而配置的；项目中的涉众不希望为他们的邮件列表设置子域。

是否有一种方法可以让后缀在确定需要中继消息的位置之后重写目标域？

我不知道我写的这篇文章是否与这个问题有关，但是我在升级tuubuntu22.04和替换mailman2时遇到了类似的问题，我不得不用指向其他解决方案的链接来记录解决方案的这里：
