I am using a separate server for SMTP outbound relay, which is actually using AWS SES. This provides one path to AWS SES and AWS SES helps prevent false blacklisting. The instructions for how to setup a separate SMTP relay are very good ( https://wiki.centos-webpanel.com/how-to-setup-remote-smtp-server-as-relay ), but they do not tell you that this additional config line will be removed by rebuilding the Postfix/Mail configuration.
I knew how to add a relayhost to Postfix, I went looking for official documentation so that I would NOT get into this situation.
Once I realized what had happened I was able to fix it, but I lost a bunch of outgoing email because of it. The above documentation should include a VERY VISIBLE note that you will have to do this every time you rebuild the Postfix configuration.
