I have used the following for email only users.
Maybe a twist on it will work for you

=============================================
Creating a user for mail ONLY
=============================================
adduser -M -s /bin/badsh newuser
passwd newuser
password newpassword
password newpassword

edit /etc/mail/virtusertable, look for, add a new line after
# Put custom additions below (Do not change/remove this line).
newuser@xxxxxxxxxx newuser

then run
makemap hash /etc/mail/virtusertable < /etc/mail/virtusertable
Insure that the domain name is in /etc/mail/local-host-names
If you edit local-host-names, restart sendmail.
=============================================
