Hello,

I have a domain with my own mail server domains (mail.mydomain.com)

aC worked previously without flaws, then once I moved the script to an upgraded plan with the same hosting company it stopped working. PHP mail worked maybe once or twice, then stopped and SMTP stopped working as well.

Then I tried setting it up with Gmail, and it worked great for about 4 days. Now it has stopped working again.

Anyone have any ideas what could be going on? Is my host maybe blocking this?

Usually hosts are not easy to work with when it comes to third party scripts, so I need to know good questions to ask them.

How can I narrow this problem down and find out if its on their end?

Thanks
