The mailing list for listmasters using Sympa

[Miles Fidelman <address@concealed>]

Anybody here find themselves having list messages bounced with error 
messages like this:

550 5.2.0moUv1n01G12CPsn0coUwb1 Message rejected due to DMARC.

It looks like things can get pretty hairy if someone sends email to a list, 
from a site that has a published DMARC policy.

This just started happening for a couple of our lists, to one specific ISP 
(Comcast).  Any thoughts?

Thanks very much,

Miles Fidelman
