I can't speak for Anthony, but it *may* be that the CIDR code in  
milter-spiff is confused by their bass-ackwards CIDR declaration.

ObDisclaimer: Yes. 198.151.235.0/22 is perfectly valid.

NORMALLY, you declare networks in CIDR notation using the first IP  
address of the range. If that were the case, it would be declared as  
198.151.232.0/22.

Again, their declaration is perfectly valid, just as I could  
legitimately describe RFC1918 space as "10.123.45.67/8" and it would  
still be a perfectly "accurate" representation of the entire network.  
It's just brain-dead. :-P

Cheers,
D
