More correctly: 0 or more :-). But look more closely at the subject
line in the incoming message vs. his regexp...

    Subject: Internet problem year 2000

A single space between "Subject:" and "Internet". His regexp has
space-*-space. In this case, the " *" will eat up the sole space in
the target string and there'll be none to match the second space in his
regexp. Regexp should be space-space-* instead. Or better yet:
[spacetab][spacetab]* (\s+ in PCRE - may be a shorter way in Posix
regexp also--I'm no expert there).

Also, the first of his Subject: tests is redundant. The second will
catch anything the first will. (2-0-followed-by-zero-or-more-zeros.)

Regards,
Jim
