I will also send this to the mailman admins, as obviously this message will be filtered by properly-acting servers. The mailman system is not handling DKIM email properly. DKIM is an anti-mail forgery measure. Using DKIM, my server attests that mail coming from me - directly - must be from my own servers, or it should be rejected as below. Mailing list systems mus change the headers to work properly with DKIM. There is information online on how to get Mailman working properly with DKIM.
