It seems very explicit that the explicit reply address is singular.. would making it e1@x.com, e2@y.com work?
It won't work. The code uses email.utils.parseaddr() which accepts various display-name and address formats, but only one address. 'e1@x.com, e2@y.com' will result in only 'e1@x.com' in the Reply-To:.
I think we should check if this is the same in Mailman 3, and change it if it is. If we have an attribute whose main function is to populate a header field, it should accept any valid value for that field (POLA). Unless there's a Very Good Reason[tm], in which case "Errors should never pass silently." :-)

I just filed <https://gitlab.com/mailman/mailman/issues/689> for this. It suggests parsing the explicit reply to address with email.utils.getaddresses instead of email.utils.parseadder.
Arguably, it shouldn't parse it at all and just copy it, but this creates potential issues if we aren't first stripping the original Reply-To: or if we're adding other items to Reply-To: due to DMARC mitigation.
