Rated 5 out of 5 stars

Works perfectly. Thanks!

I later disabled it and used the Config Editor setting "mail.override_list_reply_to"="false", as suggested by Sechstein. That works perfectly also.

Any idea what motivated the Thunderbird team to make this change in the first place? Ignoring the standard Reply-To header seems like an odd thing to do.
