mail alias problem

[Ken Hinson <hinsonkp@math.vt.edu>]

I am using zmailer 2.2 on a SunOS 4.1.3 system.  I am unable
to get the following alias to work:

   testuser: "|/usr/local/bin/mail2box"

'mail2box' is a 'sh' script to print the message to a printer.
When I send mail to 'testuser', zmailer returns the mail with the
following message:

-------------

A copy of your message is being returned to you due to difficulties
encountered while attempting to deliver your mail.

The following errors occurred during message delivery processing:


<local - "|/usr/local/bin/mail2box" 29999>: mail to program disallowed


-------------

Can anyone suggest what I need to change to get this to work?
