| I know of. The backslash is harmless here, although you should be

The second, third, and fourth backslashes are harmless there, but the first
one is better than harmless: it is vital! Otherwise a bare leading exclama-
tion point will be taken for a negation.
Actually, if there were no backslashes at all, procmail would take the
condition to mean not-not-not-not null, and all mail would score supremum.
A regexp of four adjacent exclamation points is best written
\!!!!
or
()!!!!

| Change this to * +200^1 [$][$][$] and you're fine.
or \\$\$\$ or ()\$\$\$, but dollar signs are a peculiar problem, so Era's
suggestion is best.
