I tried scrubbing undesirable parts when the project started,
but it caused signature failures when replaying to mlmmj
subscribers, so I started rejecting those mails instead.

For pure mirrors, there is "filter = PublicInbox::Filter::Mirror"
which doesn't do any modifications at all:

[publicinbox "foo"]
        filter = PublicInbox::Filter::Mirror
	...

I mainly use it with -watch, but it should work with -mda (if
PublicInbox::Filter::Vger does).

But it should work better for NNTP readers who want to check
GPG and DKIM sigs on the original message with HTML.
