A lists reply_to_address accepts only a single address.
The value in the list's reply_to_address
is parsed by email.utils.parseadder
into a display name and address to be added to the Reply-To: header being built for the message. email.utils.parseadder
returns only a single display name and address pair regardless of what the list's reply_to_address
contains. We should instead be parsing the list's reply_to_address
with email.utils.getaddresses
and adding all the pairs returned.
