yes legit problem also
This is probably a stupid question, but are those characters really
allowed in email headers?
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==?=

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.
