Recently because of insufficient balance in credit card, mail gun rejected many transaction mails in my account, and this effected our business badly.

So i request for two features:

1. Re-send rejected mails (please add code in your docs)

2. View rejected mail content

http://blog.mailgun.com/how-to-view-your-messages/

It seems currently you store only delivered mail content in your servers, Please add this feature in rejected mail.
So that we can copy the html and send it again.

Thank you.
