Hello, Ive been using Webmin and Virtualmin for over a year now but never bothered to setup email for my domains. Today I installed Postfix and I can send email from my server but when trying to receive an email from outside I get an error message that reads like this:
The error that the other server returned was: 554 554 5.7.1 <email@example.com>: Relay access denied (state 14).
I spend a whole day googling and trying to troubleshoot this error. My hosting company doesn't support my server and points me to a tutorial that doesn't answer my question.
Can you tell me where to find the solution to this error?
