Yup, the problem I see with trying that is that the mail coming in via
SMTP would be rejected and sent back to the sender.  That is, you lose
the mail.

Easier just to firewall it off I should imagine.  Something like

/sbin/ipchains -A input -J DENY -p tcp -s 194.217.242.0/255.255.255.0
-d your.dotted.ip.addy 25

should do it.
