There's two ways that spring to mind....

     1) change the password to something complex and don't tell the user 
what it is :-)
     2) Make the user a member of 'sendonly' group then define a rule 
for sendonly group like this:

g_access_group group="sendonly" access_pop="*" access_imap="*" 
access_smtp="!*" access_incoming="*"

I think that will do what you want.
