Hi, I'm trying to set up the mail service with SL Server. I got it to work so that mail can be sent internally to each user, but I can't send mail outside of my network or receive it. I'm assuming you need to set up the relay thing, of course, but I don't know how to do this or what it really is. Btw, I did port forwarding of my router to forward all requests for port 25 to my server's IP address. Additionally, I correctly set up the MX record for my mail server with my domain registrar. Also, I know that the mail services is apparently easy to set up, but I don't know how. I took a certification course in Mac OS X Server and am going to take the certification exam on the 8th, so I'm not a random idiot who thinks he can set up a server, so no hating! Thanks for your help!!
