I have godaddy's economy hosting based on linux cpanel. I have created an email address as info@mydomai.com and I send my contact form queries to that mentioned email using the php mail function. This works properly. But when I send emails from the mentioned address, it takes around 2 hours to be received on the target address.
How can this time be reduced? Is this a problem on godaddy's side?
If the mail works properly with mail($to,$subject,$message);, I think you should contact Godaddy support team in regards to this issue but before that please double check your Outlook settings.
