Ouch :-)
To some extent this is a quality of implementation matter. The server has
a clear time budget for whatever processing it wants to do, so it ought to
have a sensible way of coping with running out of time.
If the client plays tricks with its timeout then the MTA doesn't have a
clear budget to work to. So I think the idea of adaptive timeouts is
misguided.
