The trickle of failure reports I get are from addresses like these: forensicdm...@seznam.cz mailn...@segv.crash.com dmarc-nore...@linkedin.com opendm...@hamartun.priv.no prvs=1020be0dc4=nore...@manthorp.com I would expect that any mail sent to those addresses is unlikely to provoke a failure report, no matter how mangled it is when it arrives. We've had failure reports for almost seven years and I don't ever recall someone getting into a mail loop so it's not a problem in practice. _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
