I can think of lots of ways to do what you want to do (if I understand
your question). For blocking all but a certain IP, the hosts.allow file
comes to mind. You allow a specific IP, then deny the rest. In VPS2:

sendmail : 12.34.56.78 : allow
sendmail : ALL : deny

(IIRC, on VPS1, replace "sendmail" with "smtp".)

See http://www.viaverio.com/support/vps/advanced/controlling_services.cfm
for more information on VPS2; also the /etc/hosts.allow file itself ...
