Encoded words

Hi all,

We had a discussion (starting with <[email protected]>; in
german) about (fake) encoded words in Message-Ids and I came to the
conclusion, that it would be the best to ignore headers,  for decoding,
where an encoded-word may not appear, because, even though it may look
like one, it is clearly not an encoded-word, but plain ascii.

Another problem that arose, are mail addresses. See
<[email protected]>, the mail address in From: is
<[email protected]>, but slrn shows
<dö[email protected]> and attempts to send a reply to that address.

#v+
[rob@woody:~]$ vrfy dö[email protected]
5.1.3 Syntax error in mailbox address "[email protected]"
(non-printable character)
d\C\[email protected] ... Service unavailable
[rob@woody:~]$ vrfy [email protected]
2.1.5 <[email protected]>
[rob@woody:~]$
#v-

What do you think? Is this a problem that is in need of a solution?

A simple solution for Message-Id: and References: would be to skip these
headers for decoding. See patch below.

It's funny there was no one left to notice
when they came for us.
