You need to upgrade SSL on your server.

As far as the actual error is concerned, this shouldn't affect reply-to
munging. Also, it should only affect organizational domain processing.
What this means is, for example, for a domain like sub.yahoo.com, the
organizational domain is yahoo.com. This means that if sub.yahoo.com
doesn't publish a DMARC policy and mail is From: the sub.yahoo.com
domain we should look at the DMARC policy of the organizational domain,

The absence of the organizational domain data affects the lookup of
organizational domain, but is only an issue if the organizational domain
has more that two labels. I.e., this does not affect xxx.com, xxx.edu,
xxx.net, etc. type domains but does affect domains like xxx.co.uk and
many others.

Bottom line is I don't think this is affecting either your reply-to
munging or your DMARC mitigations. Is there anything about DMARC in
Mailman's vette log?
