Postfix problem Hi, Update.. I am able to send emails and I can only receive emails been sent to firstname.lastname@example.org and not email@example.com When sending the email to firstname.lastname@example.org I get this error Remote host said: 550 #5.1.0 Address rejected email@example.com Any way to solve this? Thank you in advance! #### Solved .. I have been using my ISP SMTP server and all went fine when I changed to smtp.mydomain.com at my domain control panel.
