MUA issue, as someone else said; failing that, Procmail?

Something like (untested):
:0 fh
* ^X-Mailing-List: whatever <listname@example\.org>
| formail -i "Reply-To: listname@???"
in ~/.procmailrc

That should insert the relevant line, and rename any pre-existing
`Reply-To:' headers to `Old-Reply-To:' so that you can still find it if
you want.

You can then use similar entries for each list.

If, and ONLY if, you are absolutely sure that X-Mailing-List: will
_always_ contain a line which is valid as a recipient, then you can just
have one rule instead. But this does _not_ hold in general. Doing it
lists local to your organisation may be valid:
:0 fh
* ^From .*@my-organisation.example.com
* ^X-Mailing-List: \/.*
| formail -i "Reply-To: $MATCH"

Anything further to this is off-topic for Exim-Users. Which is one good
reason to not always set Reply-To. :^)
