It temporarily blocks the receipt of a message based on the triplet IP
+ sender + recipient (storing the combo in a database).
Keep in mind that just as other anti-spam techniques require white lists
this  one  does  too.  Large  organizations often have multiple outgoing
servers causing the retry to come from a different IP address.
Which postgrey has a whitelist. Plus it only looks at the first 3 octets of 
the ip to minimize such occurances.

Postfix (the underlying MTA) runs only on *nix OS so it does require a
learning curve but all software is free but can run on hardware that
has become underpowered to runs MS OS's. Mine runs on a Dual Pent II
233 MHz with 384Mb ram.
Our nameserver is running on a ancient 200 MHz Compaq Presario with only
48 MiB ram.

More support to the efficiancy of *nix based OS's that can be configured to 
only install and run the required software for a particular function.
