mDNS or Multicast DNS can be used to discover services on the local network without the use of an authoritative DNS server. This enables peer-to-peer discovery. It is important to note that many networks restrict the use of multicasting, which prevents mDNS from functioning. Notably, multicast cannot be used in any sort of cloud, or shared infrastructure environment. However it works well in most office, home, or private infrastructure environments.

Postgrey Greylisting
Greylisting in short means that when someone wants to deliver a mail to your mail server it will simply reply -Please come back later-?. That is something all RFC-compliant mail servers do and when they do come back the mail is accepted. Most spammers and spam software are not compliant and not patient enough to try again. You will be surprised to see how effective this is.
Expose a local server behind a NAT or firewall to the internet.
