Relay access denied ?
When your server says "Relay access denied" this means a misconfiguration in your settings...
Relay access denied means:
The Postfix mail system did not want to relay a foreign domain to a foreign domain.
This means that if email@example.com want to send a mail to firstname.lastname@example.org, both domains are not handled by your server.
If it is a mail that came from email@example.com to firstname.lastname@example.org, you need to verify:
- You have correctly added you domain in your organization.
- You have compiled the postfix settings
The top icon with a down arrow is a command to order to apply the whole settings on your Postfix system.
The Postfix mail system did not want to send outgoing mails.
If you need to send out a mail and you receive this error, this means that your network is not correctly set into the Postfix Network settings.
The Networks section under Routing & Network allows you to
define your internal ranges/addresses allowed to send email to foreign domains.
