You can have free email with your Free hosting account but you cant have free account with your own domain like
[email protected] unless from where you bought your domain they give you that facilities which i never see now a days because of cheap domain name.
anyway :
about Mx record, its define where is your Mailserver
suppose you made your own mailserver and your public ip is 66.77.66.77
now you will have to tell your domain company to change the MX record to 66.77.66.77
what does it mean taht : when i will email to your doamin [
[email protected]] , my mailserver will check who is responsible for Dns management for the domain abc.com
so from Nameserver it will know Example ,fasthost.co.uk is the responsible for the Dns management of this doamin
so it will go to fasthost.co.uk Server and will ask for the domain abc.com
then fasthost.co.uk will say well , we have the Dns record, then my mailserver will ask : where is the mail server for abc.com, so fasthost.co.uk server will say, according to our record (MX) it at public ip 66.77.66.77
then my mailserver will go to address 66.77.66.77 and will get your mailserver and will submit myemail to your mailserver
its the theory!!
