Mail Can't be received using postfix on fedora core 2
I am trying to setup a mail server for sending and receiving at my home computer with fedroa core 2. My website and mail host are on the same system.
I have configured postfix to send mails and working fine. I can send mail to any internal or external e-mail addresss, but when I send an e-mail from my yahoo account to a user on my domain, I can't receive it. I would really appriciate your help as I have been trying a lot but things are not working.
I red on some post that postfix can not receive e-mail , it this true, if yes then what should i be using for receiving e-mail from any internal, external e-mail address.
