If you can find something that does the Sieve protocol, I think you will have found just what you want. Sieve is a protocol that lets you upload filters to the server and have them applied as the mail is delivered to the users. I have set up Sieve on my server setup (about 2 years ago), but I was using Postfix, Dovecot, and the Sieve plugin for Dovecot. So ...

This is the correct message since a third party website is connecting to your server and is not able to send out emails to external domains. Ideally, as per the configuration, if you send an email to one of your own domains, then it should be delivered. Had you been having an open relay, which means accepting emails for any domain, then it would be a big ...

Sending mail to domains not hosted on your Postfix (external mails thus) is only possible for IP and networks allowed to do relaying by the configuration of Postfix. In Postfix, this is achieved by giving these allowed IP's and networks to the mynetworks configuration directive in main.cf. In your case, it shows that only localhost is allowed to relay mail ...

Well, turns out this was indeed very easy. In main.cf include the IP address of the SmartHost: mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 xxx.xxx.xxx.xxx and add this line to the end of the main.cf file: smtpd_client_restrictions = permit_mynetworks, reject Reload postfix: sudo postfix reload Now any connections from IP ...

Sorry if it is not the step-by-step howto that you were expecting, but you need to give more details about your configuration. Also, I suggest to split your question into several post. But anyway, I have some clues / guidelines for your to help this to be sorted out : At DNS level (at your registrar), you can define different names pointing to the same ...

The easiest manner in which to accomplish this would be to go back to your router, and modify the rule redirecting port 25 traffic to your Ubuntu machine. Allow it to only redirect traffic from your smarthost, and dump the rest.

Personally, I would highly recommend us use Mandrill via its RESTful API to handle your application generated outbound mail. This would provide you with templating, tracking, analytics, and help with spam filters. The cost is very reasonable too. https://mandrill.com/
