Sendmail can be configured to look up information in an LDAP server and forward on non-local mail. However, for a small number of accounts it would probably be easier to set up forwarding between the machines. People reading email using imap will need to use the domain name of the the machine that will actually store their email, and not the generic name. Though again it is possible to set up imap proxies (such as perdition) that can look up where a person's email is really stored and connect to that server on a user's behalf. This seems like overkill for just a few accounts. Is there some reason you use two separate machines for email with just a small number of users? Even if you want to split up shell access for some reason, it might still make sense to keep all of the email on one server.
