CentralNic's email automaton used to be a pipe filter for Sendmail, but it
used to break a lot - if there was a lot of simultaneous requests the
loadavg of the server would go through the roof.
I rewrote it as a daemon that polled a POP3 mailbox instead and it's a lot
more reliable. If the script falls over or something gets corrupted, the
mail then gets queued instead of lost, and the server now doesn't even break
a sweat because it's not constantly recompiling the script. Downside is the
memory footprint of a permanently-resident copy of pop3d and the compiled
script.
