Addresses with the same domain as my vhost are causing Postfix and QMail to revert to a local network instead of just outright sending the mail. I thought I had this problem fixed with the Luke Tarplin method, but commenting out those lines in the
/etc/postfix/main.cf have stopped working since the 10.4.4 update to PLESK for some reason.
I've seen other suggestions including adding MX records, modifying the
main.cf in different ways. I know very little about MTA's and even less about DNS settings.
Does anyone have any advice on a solution to making Postfix treat all email recipients the same and just send the email instead of reverting to local?
Below is from my maillog, I have it sending to 2 emails, 1 a gmail, one with the same address as a vhost. As you can see, one gets sent, one does not.

UPDATE: This is 100% a PLESK issue, and it applies to almost all versions of 10 and 11. The QMail MTA also reverts to a local handler if the vhost domain matches the email recipient.
