Looks like you’ve got it working fairly well — nice job. Most people don’t get that far…
Are you currently set to ‘both’ (rather than ‘inline’)? I just tried it and didn’t see that message. Were you seeing that message on the screen or in your error logs somewhere maybe?
I’m not looking at the code, but if I recall correctly I think that message comes up when the server rejects sending the email. Are you using a shared hosting company for your site? My guess is that they are probably blocking the outgoing email. You probably need to install either Custom Sender For Email Before Download plugin or the Postman SMTP plugin so that you can set the From: value of the email. I’m guessing that will fix it (this is a big guess since I don’t have a lot to go on based on your description, but I suspect that might be it).
To be clear, EBD will send 2 emails when you are set to ’email’ or ‘both’ in the EBD settings. One email (which I call the “notification email”) is sent by Contact Form 7 and it gets it’s From: and To: values from the ’email panel’ of the CF7 form that you created. The other email is sent by EBD code itself and it picks up some default From: value (from the unix account of the system sending it — which is why it’s wrong on shared hosting). You need to use one of those two plugins to set the From: value so that it is a -real- email address that matches your domain name. In other words, it needs to be an actual working email address that can send & receive email and it needs to be at aiasurety.com
That -might- fix things. One advantage of using Postman SMTP is that it has extensive diagnostic capabilities, so if things still don’t work, it can probably tell you why…
