If an administrator explicitly requests an override (despite
some documented caveats), he should be willing to accept the
risk that a milter might first request some changes to a mail,
then changed its mind and rejected or tempfailed it.
I think a warning in a log would suffice. For me, it would be
acceptable one way or another (with or without milter edits
to a message being applied).

In this particular case the header size is limited to 32 kB,
although I don't think it is worth the effort to anticipate
anything that might go wrong in a milter and have a workaround
available. Today is a header size, yesterday was a header field
length, tomorrow will be something else.
