[Bug 1568445] [NEW] DMARC mitigation can check an invalid domain if the From: local part contains a quoted '@'.

Public bug reported:

A message with a From: address with an '@' in a quoted local part has
been observed. While this is probably bogus, it confuses the DMARC
mitigation code that splits off the domain at the first '@'. The code
should probably split at the first '@' from the right.
