Description: extremely simple MTA to get mail off the system to a mail hub
 A secure, effective and simple way of getting mail off a system to your mail
 hub. It contains no suid-binaries or other dangerous things - no mail spool to
 poke around in, and no daemons running in the background. Mail is simply
 forwarded to the configured mailhost. Extremely easy configuration. 
 
 WARNING: the above is all it does; it does not receive mail, expand aliases or
 manage a queue. That belongs on a mail hub with a system administrator.
