Yes, please close it.

For the record, two implementations are here:
https://github.com/trusteddomainproject/OpenDMARC/blob/master/libopendmarc/opendmarc_policy.c#L574
http://www.tana.it/svn/zdkimfilter/trunk/src/zaggregate.c#line=725
(if your browser doesn't implement RFC 5147, search "check_addr")
