i'm so tired trying to set up bind server, i can send and receive mail from server and receive mails from internet but when i tried to send mails from external all mails are rejected
550 5.7.1 <firstname.lastname@example.org>. Relaying denied. IP name possibly forged [201.129.204.xx]
I just looked at documentation and saw sendmail by default does not support it but i changed 127.0.0.0 to 0.0.0.0 in smtp, but i did not work..
As far now i just chequed lunix firewall and opened aaaalllllll !
by the way i have linux 9
