Emails showing from host.myserver.com instead of mydomain.com

Not sure if this will make sense, but when I try to send an email from [e-mail] it says sentby [e-mail]

Is there anyway to fix this?

Answer 1

Try sending mail like this and see if it works for you:

<?php
mail($to, $subject, $body, $headers, "[e-mail]");
?>

Do you have a “From: [e-mail]” in the $headers as well?
