Copies standard input to a qmail-style maildir

Safecat copies standard input to a qmail-style maildir as reliably and quickly as qmail itself. It can be used to deliver mail messages to qmail folders, or to spool data securely for later use by non-email-related applications. Safecat was originally written as a spooling utility for a CGI-based data collection application; it was inspired by the super-reliability of Dan Bernstein's maildir algorithm.
