You can permit relaying from selected hosts or selected subnets. If the users have permanent IP addresses, or their addresses are all from the same subnet (and there aren't any potential spammers among them), there's no problem doing this. It can be done in sendmail, but offhand I can't tell you how. In qmail you can run it off tcpserver and have a rules file for tcpserver telling it which hosts/networks are allowed to relay.
