    I figured as much... still not what you want though...;-)

    Is that the answer you expected? 

I wasn't sure what you were trying to do, since your subject
said you were trying to block hosts by domain, whereas your
smb.conf file only seemed to have a "hosts allow":

    hosts allow = 172.25.0. .example.com

...that would only work for a user named 'susan' who has validated
against the the server.  I.e. When you go to map 'data' to a drive,
I believe you would need to 'connect using different credentials',
and enter susan's creds in the dialog.
