Question
Why won't postfix deliver mail to own domain?
So I followed the tutorial here to set up Postfix as a send only smtp server.
I’m currently using Gmail for business as my mail client for my domain. Any email sent from my droplet (my domain) to an email address on my domain doesn’t get sent. I never get the emails in Gmail. I can get emails sent to other domains from my droplet though.
The only workaround I’ve found so far is to edit the /etc/postfix/main.cf file and change mydestination from “mydomain.com, localhost.mydomain.com, localhost” to just “localhost”.
I’m just unsure if in doing that I’m opening up some sort of security hole. Is this the correct way to handle this? Is there another, better way?
Thanks

Hi!
Per the Postfix documentation on
mydestination, it should contain the list of domains whose emails are hosted on the local Postfix server so that they are handled internally and not relayed out to external systems.The workaround that you found is actually the correct solution. By removing your domain from
mydestination, Postfix will send any emails to it to the servers that are listed in its MX records, which would be Google Apps in your case.
