I have less than 30 users, all of whom need to be able to mail others within our domain, but only some of whom should be able to send and receive mail externally. The box is set up with Sendmail 8.8.5 and QPopper 2.2, and all out of domain traffic goes to our ISP via UUCP - there is no other connection to the internet. Everything appears to work fine, except that I can't figure out how to restrict external access. Can anybody point me in the right direction regarding this? - Ian
