  The terse disable-MAIL dept 
 The Question is:
 
Is there a way to disable Mail for general user accounts?
 
 
 The Answer is:
 
  Yes, assuming you are refering to remote email -- simply remove
  the NETMBX privilege from the offending user(s), and the user(s)
  will be unable to perform network operations.
 
  Yes, assuming you are refering to receiving email -- you can use
  the AUTHORIZE flags DISMAIL and DISNEWMAIL to disable the reception
  and notification of email.
 
  Yes, assuming you are willing to entirely disable email on the local
  host -- you can remove the MAIL-related images from the list of
  installed images, and deinstall the images.
