[solved] I can't get emails!

[Naradam]

All of the records for the domains are set to be my ip by the domain registrar, btw the reverse dns of the machine was bad, I just fix it. (was an old domain, that I dont have at the time..)

Or you mean by my isp should the dns be changed? (not same as my registrar)

or I ask What should I see where?

( my hostname is reolving, even with -f, in the hosts there are set, in the resolv.conf I have my isp-s two nameservers set... should there be the registrars too? or?)
