i'm not sure, if this is a good idea. what about outgoing mails, that get
delayed (i.e., cannot be sent immediately)? don't they need a running
daemon? of course, they probably would get sent when a new mail is sent,
but this may be ages later ...

i like the idea of denying all incoming packets on port 25.
alternatively you can setup relay/delivery blocking rules in the
sendmail-config. but it's just a question of time, when the next security
hole is found in sendmail, so i prefer low-level-blocking.
