It's one of the mechanisms used for "you've got mail" notifications.
IIRC there's a "biff" option you can set to stop Postfix trying to do
this kind of notification, but I could be wrong.

Postfix is pretty secure by default. You could always firewall out any
incoming connections on port 25, but if you don't want to worry about
firewalling I wouldn't worry too much.
