If the "to" in the alias begins with a pipe ("|") then it is assumed to
be a script.  SO you can  write a script that reads stdin and deposits
the message somewhere.

freebusy:       | /etc/smrsh/publishfreebusy.sh
[awilliam@estate1 awilliam]$ cat /etc/smrsh/publishfreebusy.sh 
#!/bin/sh
cat > /tmp/freebusy.ifb

You script *MUST* be in smrsh or sendmail will refuse to run it,  this
prevents the execution of arbitrary programs via e-mail.
