That's completely unhelpful.


Just in case you missed it the last three times I said this: make the 
message compliant, then sign it.

I guess you missed where I said that you'd be better taking that up with 
Eric.

Strange. You must have missed where I suggested you take it up with
Eric. That suggestion being fix the problem at the layer creating the
problem. If your SMTP listener is presenting you with mal-formed mail,
then that's a contractual matter between you and your SMTP listener to
resolve.

You and it should agree on what to do with malformed mail prior to
bothering with verifying or whatever else you do.

Ditto your submitter. If it presents you with non-compliant mail, make
it compliant prior to signing. Conflating SMTP or SUBMIT bugs into
another protocol is entirely unnecessary when you can fix it much more
cleanly at the boundary.

All I hear you saying is that such boundary fixes should be uniform as
far as is possible. That sounds fair.


Mark.
