Hi thanks for looking into it but my folders were all enabled, as you can see in this screenshot I took. I've tried sending a few more test emails through mxhero, and now what is happening is that they appear in my Sent mail but are not actually being received by the email addresses I'm sending the tests to. 

I'm really freaking out because I'm started to realize that a number of emails I thought I had sent were just sitting in my Drafts folder. This is a serious problem as I've been trying to follow up with people and now I don't know who received my emails or not.

Can you please let me know what the status of this issue is and why my emails are not sending?
