Postfix: Relay access denied whenever sending e-mail
Hi, today my e-mail server stopped sending outbound e-mail. I am using Postfix for the sending side and Dovecot for receiving Whenever I try to create a new message in Evolution and send it, it says "RPCT TO <e-mail address> failed: Relay access denied". This only happens if I use Evolution to send e-mail. If I use the SquirrelMail webmail program I have on my web site, everything works fine. What's wrong?
