What one could do, though, is an ldap lookup in $recipients to find a user
preference (a list of charsets that they don't like). Unfortunately, we
can't do this in the recipients ACL, because we don't have the body.
However, most messages have only one recipient, so that shouldn't be too
much of a problem.
For multiple recipients, one could maybe 4xx the message, store a message
ID and charset in a database, and reject per recipient when we see it next.
To avoid loss of mail (when the sending server doesn't resend temporarily
rejected messages), one could even 4xx it, deliver it to people who want
the message, and 5xx the rest of the recipients next time around.
