I wouldn't worry, this rule currently scores 0.001, and I doubt it's ever going to have a significant score as it stands. For me it hits more ham than spam. It's actually pretty easy to fix it so it doesn't FP on SRS, mailing lists etc, by looking for the from domain anywhere in the envelope address rather than matching on the end of the envelope domain. For me this would remove most of the FPs without significantly affecting the detection of genuinely mismatched domains. However it would still hit a larger percentage of my ham than spam.
