Program to process mail?

[dl rubin x-2566]

To all the mail wizards;

I am looking for a program that will automatically monitor and respond
to incoming mail.  It should be able to read the header and/or text of
the message to determine what should be done, process the mail and then
send a reply back to the sender of the mail.

I have assummed the existance of such programs from other discussions
on the net.  Is there one available at an ftp site, or could someone 
send one to me at dlr at sooner.udev.cdc.com.

Thanks.
