[erlang-questions] Erlang for a SMTP Server?

While erlang seems the perfect language and I always enjoy implementing 
alternative solutions to problems that have previously been solved, if 
you are under the gun to produce something for your job you might want 
to look at OpenBSD.

There is a spamd (spam daemon) that comes with the installation.  Setup 
your firewall to relay packets to your SMTP server, but use the spamd to 
block spam.  It uses whitelisting and greylisting, forces everyone to 
try twice before they get into the whitelist and stutters very slowly at 
spammers.  It's been around for a while, it works and it takes very 
little load on a machine.  At the same time you will be able to take 
full control of firewalling and logging all packets that come through 
your external machine.
