Ah, gotcha.

 > 212.1.128.0/19        (255.255.224.0)

You should be able to just enter this as the IP "212.1.128.0" and such 
"255.255.224.0" as the submask.  You can ignore the /19, IMail will figure 
that out from the subnet mask.

>212.157.128.0/18    (255.255.192.0)

And for this, you would use 212.157.128.0 as the IP, and 255.255.192.0 as 
the subnet mask.

>212.159.128.0/17    (255.255.128.0)

... and 212.159.128.0 with 255.255.128.0 as the subnet mask.

So if you just take off the "/xx" you should be fine.  IMail can figure it 
out by counting the number of binary 1's in the subnet mask.
