After all this discussion my solution to the original problem would be "just reencode and break DKIM".
The reasoning: If a system does not support 8BITMIME it would probably be some legacy system and not understand DKIM either. If there are a few odd exceptions to the rule, that should not be a huge problem. You should only softfail with DKIM errors anyway; hardfail is asking for trouble. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
