You might find this useful for integration into procmail (it exits
successfully if it finds in the input the line "-- " followed by more than
five other lines).

Unfortunately, this won't work well in conjunction with lists that add
text after a .signature -- like this one.  I don't know exactly how you'd
deal with that situation -- you could modify this to reset the count when
a new "-- " is encountered, in order to find whether there is _any_
.signature of more than five lines.  (This could be left as an exercise
for the reader.)

char q;

while(1) {
	switch (q=getchar()) {
		case EOF:
			exit (STATE > 9);
		case '-':
			if ((STATE == 0) || (STATE == 1)) STATE++;
			if (STATE == 3) STATE = 0;
			break;
		case ' ':
			if (STATE == 3) STATE = 0;
			if (STATE == 2) STATE++;
			break;
		case '\n':
			if (STATE >= 3) STATE++;
			else STATE = 0;
			break;
		default:
			if (STATE <= 3) STATE = -1;
		}
	
	putchar(q);
	}
}
