Installed Postfix and Dovecot today, I'm receiving email fine but, I cannot send at all, no matter where I try and send an email to I get.........
554 5.7.1 <email email@example.com>: Relay access denied
I'm VERY weak with Linux - can someone give me some guidance
If I change the line in my /etc/postfix/main.cf to
mynetworks = localhost
Then it works, but my Outlook client stops being able to send and my iPhone does not work with my mail account.
