You can set up users on either system.  You've got two issues:

1. Telling the email system on which system to deliver the email.
2. Telling the users on which system to log in to read the email.

1.  Is the hardest part.  You can only have one primary mailserver for
your domain.  You can have the old users use (for example, only)
name@xxxxxxxxxxxx and the new users use (again, for example only)
name@xxxxxxxxxxxxxxxx, and create MX records so mail to surfmore.net
will go to one.surfmore.net, and mail to new.surfmore.net will go to
two.surfmore.net.

This is the best approach, because it puts NO additional workload on the
old RaQ.

However, it means some users will have a different domain.  This, by the
way is the way RoadRunner does it.  One of my friends has an email
address name@xxxxxxxxxxxx (he's in southern California) while one in New
York may have hisname@xxxxxxxxxx

Problem is that if customer wants a second mailbox once you've loaded
the first machine, he may have to have his second email address at
another domain name.

2. Another way, much less recommended, but easier on your customers, is
to set up the new users on the second system (i.e., two.surfmore.net),
and add a line to the bottom of /etc/virtusertable for each new user:

user@xxxxxxxxxxxx           user@xxxxxxxxxxxxxxxx

(use a tab in the middle, not spaces)

Of course if you do this, you've got to rehash the file:

# makemap hash /etc/virtusertable < /etc/virtusertable

And then restart sendmail (you can do that from the gui), or you can do

# kill -HUP `head -n 1 /var/run/sendmail.pid`

(those are both back-single-quotes, to the left of the "1" numeric key
on the top alphanumeric row of your keyboard)

The second way uses more resources on your first machine though, as all
user mail will be forwarded through it.
