Reject... (I change corrupt but readable, by mail to trash), No, I don't like
the idea,...
Well, rejecting it make the sender aware of the problem.
Otherwise you receive it corrupted: either way the message is invalid so
it id not a big problem if it is corrupted even more.
But seem that in this case the one that violates more the RFC is JavaMail, that places
"quoted-printable" instead of "7bit" in a message without
Content-Transfer-Encoding when modify any header of msg.
Well, I don't like JavaMail, and I lost a lot of days try to workaround
its MANY bugs, but I think this time it is not javamail that is doing it
wrong.
It is clearly stated everywhere that you cannot have 8bit chars in the
text of a message unless you use Content-Transfer-Encoding: 8bit. If no
content-transfer-encoding is there there is no rule about what to do.
Javamail adds quoted-printable simply because it find the 8bit char: try
removing the 8bit char and I bet that Javamail won't add the
Content-Transfer-Encoding anymore.
So the source message is wrong: if you add Content-Transfer-Encoding:
7bit you will change the message and corrupt it more anyway... There is
no (I can't see it) clean solution/workaround for this: you can fix some
mail, but mangle much more the others if you add workarounds.
