Hi, yesterday i received a failure-notice; Remote host said: 554 5.7.1 <i...@domain.com>: Relay access denied --> this is the error-message which i received from the final recipient. The email was send from our webserver. The webserver (postfix) sends the email via relayhost (another external postfix Server) to the world outside. Does this mean that the email provider from the recipient doesn't allow the use of relayhosts? Is it generally better to not use relayhosts? ..we had problems with spam some years ago if we sent mails directly with postfix, so we used our external email provider as relayhost. But i think this was because we didn't have a valid RDNS entry. So should i switch off the relayhost?
