Write a very small wrapper program (in C for speed, or Perl) to wrap the
program and catch the signal, then return a normal error code. Exim can
be configured with temp_errors to treat certain exit codes as temporary
errors. If your program returns EX_TEMPFAIL (commonly 75) then this is
one of the values in the default temp_errors.

Exim doesn't support treating signal exit as a temporary failure, hence
the need to wrap it. You can take the opportunity to use setrlimit() to
ensure there are no core files, too.
