The better option is to configure amavisd-new to accept bad headers. I'm pretty sure amavisd-new accepts bad headers by default, but here are some settings you can look for. # amavisd.conf $final_bad_header_destiny = D_PASS; @bypass_header_checks_maps = (1); You could configure postfix to reject such mail, but then you'll lose otherwise legit mail. -- Noel Jones

No, raw 8 bit characters are not allowed in headers. They must be encoded such as they are in this message. Subject: Re: postfix strip =?utf-8?B?w6bDuA==?= =?utf-8?B?w6U=?= (highbit chars) Most MUA's take care of encoding the headers automatically, but it's a common enough problem that blocking mail with 8 bit characters in the header is not recommended. At any rate, unless 8 bit characters in headers are causing some specific problem, it's not worth blocking them. -- Noel Jones

The functionality exists for you to be strict on this. By all means, go for it. The rest of us still care about ensuring delivery of legitimate mail, however 'broken' it might appear to you. :)
