I posted this question in the sendmail forum but got no responce so I thought I'd try it here. I am using sendmail for my smtp server and qpopper for my pop3 server. I can send mail to the outside world and also receive mail. I want to be able to let some people use my server just like they would their ISP's mail server. When I try to use it from a remote machine, it won't connect to the smtp or pop3 server. I get nothing in my mail log. I've also checked my firewall to see if it was blocking relaying and it was ok. I'm at the point where I'll take any advise, even if it's wrong.
