Yes, each AIX user is an email account. I think Notes, and the
sendmail.com product can maintain their own user database. But the
sendmail.org sendmail relies an a Unix user existing for each mail
account, as far as i know.

True, and if i start adding multiple mail servers, i may look at this.
However, for the first machine (the NIS master), you still need a way to
get all the users on there!
I believe i have it solved by creating /etc/passwd manually, and using
usrck, pwdck, and grpck to get the /etc/security files in order. Then
creating home directories manually (with a script). I don't think mkuser
was ever intended to add this many users! Also i am not adding each user
to /etc/group, but the gid in /etc/passwd does point to a valid group.
Not sure if this will cause any fallout, but i don't plan to use group
permissions much anyway.
