exceptions, which could be configured via SpamAssassin rules.
How could a SA plugin help?
Isn't this something that should be handled at MTA level?
Well, we are using amavisd-new in prequeue filtering mode. In our
configuration a score of 5 will quarantine an email, a score of 10
will
reject the email.
You can submit a feature request in SA's bugzilla....
and in the meantime may want to look at
http://sourceforge.net/projects/opendmarc/
I proposed a DMARC plugin for spamassassin on the dmarc mailing list
last year, to make it easier for people to give DMARC a spin. They
didn't really like the idea (I still do), because a simple plugin
wouldn't do the report sending, which is an important part of DMARC.

Matt Simerson (who is on DMARC-diskuss) already did the necessary work
(Mail::DMARC) which allows to programm a full featured plugin with
reporting. Therefore writing a plugin is not that difficult anymore.
