Can Send Email, But Not Recieve; Relay access denied
I'm stuggling to get ISPConfig up and running. I followed the Ubuntu Perfect Setup. When I send test emails to user accounts that I have set up, I quickly get a bounce message back. Here's the complaint in the return mail:
PERM_FAILURE: SMTP Error (state 9): 554 <email@example.com>: Relay access denied
I've searched this forum and found lots of similar problems, but mostly about SENDING mail rather than RECEIVING it. I've tried some of the solutions suggested in the similar topics, but nothing has worked, so its possible that I've messed things up worse.
Again, I can send emails, but not recieve. Any help would be appriciated!
