Hi Matt.

I am using Vendr 2.4.1 and Vendr Checkout 2.1.2 and the default workflows, e.g. no custom pipeline.

I have copied Application.Web\App_Plugins\VendrCheckout\views\emails\VendrCheckoutOrderConfirmationEmail.cshtml to Application.Web\Views\Emails\VendrCheckoutOrderConfirmationEmail.cshtml and configured the template to my requirements.

I have updated the Order Confirmation email template view path to ~/Views/Emails/VendrCheckoutOrderConfirmationEmail.cshtml .

Now, whenever I submit an order through the checkout process, or Send Email via the backoffice on an existing order, I get the following error:

System.AggregateException: AsyncHelper.RunSync method threw an exception. (The SMTP server has unexpectedly disconnected.)

   at Vendr.Core.Events.Notification.Handlers.Order.SendFinalizedOrderEmail.Handle(OrderFinalizedNotification evt)
Although it would suggest an issue with the SMTP server, no change has been made to the SMTP server and it was working fine with the default template before this change to a custom template.
Even if I switch back to the default Vendr email template, I still get the error.
Any ideas?
