[SLUG] Program delivery with Sendmail

[Peter Rundle <peter.rundle@xxxxxxxxxxxxxxxx>]

Does anyone have any good urls to on-line docs on program delivery using
sendmail. www.sendmail.org is terrible.

I've put an entry in the /etc/aliases file 

  user: "|/bin/myprog" 

but I always get an error mailed back to root, the guts of which is,

     ----- Transcript of session follows -----
  sh: myprog not available for sendmail programs
  554 "|/bin/myprog"... Service unavailable

The program exists and is executable for all (ok maybe not a good idea
but lets get it working first ;-)

So what gives?
