Hi.

Im now running Exim 3.36 with POP before SMTP.
When people have Poped they can send mail with is good :) , but they can send mail that aren't my domain.
As before my domain is reboot.nu, and people send mail thru me with blabla@???
How do I stop this? So the senders only can use my domain name?
