I'm definitely leaning towards SMTP being the culprit. Have been for a while.
I tested out SendGrid rather than routing these emails through Office 365. I saw a much better level of performance. I've changed our email provider to SendGrid on the Live site and we should see a lot better performance now.
I don't imagine we'll exceed the 400 emails per day cap for our free sendgrid account anytime soon, so that should be pretty well in hand.
I'm optimistic that this will drastically reduce the amount of duplicate submissions that we get. :+1:
I'm not sure if it's the webform module or if it's the SMTP module, but it's pretty slow and resulting in duplicate submissions because people are waiting forever.
We should investigate and resolve the trouble.
