I was having great success sending emails through several custom pages, a CMS (Open Atrium), and a custom email newsletter sender on my website. Today I tried to send out a small newsletter mailing and it failed when I ran a test to myself. No errors, but no email. The same goes for my contact page, and my CMS. Nothing has changed except that I don't get emails now.
I tried calling customer support. I haven't exceeded any quotas or email sending limits. Everything is "working". They won't support this issue however because they don't support "custom scripts".
For kicks I tried a simple script (below) in my root directory. No errors. No emails either.
Any thoughts on how to proceed? Do I need to call again and talk to someone else? I haven't had any issues until just recently. Do I need to switch hosting services?
mail("email@example.com", "Test Message", "This is a test message. Can you see me?");
