Create my own email server

Hi everyone!!

ok. I just register my domain name, soon will be having internet cable(comcast). I will like to set up a email server for my family. I have been reading a bit but I,m I little confused with the xm records, dns, And so on. Is for my family use and not for business. And plus for my expirience to learn this stuff. Is there any guide avaliable for dummimies or, for some of the members of this forum to point me to the right direction.

PS: I am a newbie!!! 🙂

Thanks in advance
