creators of Papercut of why did they build a useless app?
Since I don't know what a `Papercut` is, I'm not excluding such possibility
Especially, considering that a simple
{$ifdef debug}
Email.SetHeader('Debug-Save-Original-To', Email.Recipient);
Email.Recipient := 'yourmail@domain.com';
{$endif}
Email.Send;
covers your requirements (as you described) without it.
