We have the same problem (and not that far away from you either
:-). By the way the maximum line length is configurable in Netscape's
server but we were told it is a security risk to allow longer
lines. Its not a major problem for us as the only message we receive
with this long a line is generated by one of our own systems which
I've hacked up a little to avoid it.

As for solving it in Exim I'm not sure how you'd do it apart from
using embedded perl.
