I need this feature, too. There is some support for the same functionality built into notmuch. The big problem for me is that .notmuch-config does not support wildcards (e.g., *@mydomain.com or user-*@mydomain.com). Compounding this issue is that, other than notmuch reply's internals, notmuch pretty much suppresses the Delivered-To header, which is crucial for knowing in a non-heuristic way where an email was actually delivered to. I want to compute my From: header based on the Delivered-To, so I created a mail-delivered-to-reply-from alist that maps one to the other. It's pretty horrifying what I had to do to get this to work, but it looks something like the following. (Apologies for any mistakes, I had to strip out additional complexity I have for other things in there, so it's not verbatim the code that I'm using, but it's pretty close.) If someone knows a better way of doing this with stock notmuch, please let me know. I know it's simpler to fix notmuch-reply, but I really don't want to start depending on a custom-forked version on the notmuch binary, as I read my mail from multiple operating systems and I'm sure I'd forget to update one of them.
