(with pop3 clients) I can fill in any made up name/account i want in my pop3 mail client's userid and address and send it by way of my server to anywhere and apparently it delievers it and says it's from fake_user@www.my_domain_name.com or what ever even though fake_user doesn't exist on my system. if possible, how can i set things up to only allow known/valid users to send pop mail through my server? I'm running FreeBSD 2.2.6-RELEASE and qpopper-2.41b1 thanks in advance, rwmcfa1@sac.uky.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
