After more than 2 days with the MX record set to aspmx.l.google.com, the test php script
mail('firstname.lastname@example.org', 'Test mail', 'Hello! This is a simple email message.');
does still not sent anything to myname (at) yahoo.com (a working email on Yahoo I don't want to reveal here). The Google Apps works since some days so I don't know where is the problem.
Also please note that you will have to set either the "TO" or the "FROM" field of your e-mail form to be an operational e-mail address created with your account with us, so the mail form could be operational.
I don't quite understand: An operational email adress created with Freehostia means that I have to set the MX record to mbox.freehostia.com. Since there is only one MX record, how then can I set it at the same time to gmail?
I would really greatly appreciate clear instructions about this.
