OK, you can connect to the MX server. Of course if you tested it from your server.

And what about logs?

This is exim mainlog resulted by running

<?php mail('[email protected]','Test email','This is a test.'); ?>

I did not understand if I have to do anything regarding to this comment? Do you need anything else?

According to your logs you did not disable Local Delivery for tolue.com domain. So I suggested that you re-read post #12 once more again and follow instructions from it.

Thank you Alex. Your first suggestion was the best solution that I strangely could not determine it. I though I have to remove MX record from DNS settings, and did not find "MX Records" option in DA
So sorry for my mistake, and thank you so much for your assistance.
Problem solved completely by unchecking "Local mail server" option.
