You may actually run into a OS/shell limitation after you try to extend
the exim one. There is a limit on the length of commands there too but I
don't know if off hand. I have run into it before though when trying to
pass lots of arguments to programs.
If there are many many options, you might be better off putting them all
in a file that your program parses while the mail body is passed via the
pipe. Might be counter intuitive but it will prevent hitting the overflow?
