Can you?! This is how other servers/mail clients connect to your SMTP server anyway. What you could do if you have firewall (or not) is to have your ISP be MX for your domain and then forward (statically) mail to your SMTP server. This way you only get connections to your SMTP host from single machine. Thus limit access to your SMTP from that machine only. Hope it helps.
