There's no builtin support in Exim. In fact, not all possible lines
*can* be folded - you're only allowed to insert a line-break before
(certain specified instances of) whitespace.

You could play with ${sg} and split on *any* whitespace, once a
long-enough line had built up - but you might break something
by not recognising these special "foldable white space" cases only.


Or you could refuse such messages in the first place, and make
it the sender's problem.
