I don't believe that the python DNS resolver module is a stock part of
the python distribution. I may be wrong about this, but I recall
explicitly installing it here. If, for any reason, the working version
of python on which Mailman depends was upgraded or up-versioned, this
package may need to be manually re-installed for the new version.
If the symbolic link /usr/bin/python shows a creation/modification date
that coincides with the failure of your DMARC lookups then this is a
possibility, albeit an unlikely one, but it's easy to check ("ls -l
Mark's tests should help you narrow the problem down.
