Lucas Veiga asked:

Im trying to set to my postfix send e-mails from my server, not from Google SMTP and it keeps trying to send over Google’s SMTP:

I dont want it to user Google’s SMTP.

I answered:

The email for your domain lucasveiga.com is handled by Google according to its MX records. Thus in order for it to be delivered, it has to be sent to Google!

If you don’t want to use Google for your domain email, then you will need to stop using Google Apps to host your domain email, and switch to another provider.

Of course, the real problem is that you did not follow the advice given for your first question, and you should do that now.
