Sendmail doesn't provide an option for that. It provides three options for 8BITMIME handling, one of which is "strict". That option makes sendmail reject the message if it is not valid 8BITMIME; it does not provide any hooks to manipulate or inspect it (e.g. to determine the contents of the header). The other two options accept the mail anyway (DJB's just-send-eight) or convert it if necessary (impossible since the data is not MIME). I'm asking you to please fix your mail server so that it doesn't send or relay invalid data. exim tends to be broken WRT 8BITMIME, which is exactly why I don't use it. I honestly think it's completely legitimate to reject data that doesn't comply with the standards, and making the sender bear that burden is the right thing to do, IMO. Otherwise the sender has no motivation to change their behavior. I understand Postel's Law, but that was before security concerns and spam and it assumes everyone is acting in good faith, which is demonstrably not the case on the Internet today. You, of course, are free to do nothing and nothing will change. But as I said before, I'd like you to please give some thought to fixing it. If you choose not to, you are free to mark the bug as wontfix but please do not close it (since it is not fixed). -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
