And that was working fine for all the IP addresses? :-?

This is the format I always use.

Mmmm... there has to be something wrong (then or now) given the other 
format worked for you but after reading the decription from Postfix 
manual I understand the allowed options (regarding long lines) are either:

# long lines
mynetworks = ip/block ip ip/block ip ip/block ip ip/block ip
 ip/block ip 
^
 (whitespace goes up there)

# long lines
mynetworks = ip/block, ip, ip/block, ip, ip/block, ip, ip/block, ip,
 ip/block,ip 
^
 (white space goes up there)

And Postfix is very nitpitcky with the correctness of the file formats :-)
