Add option to forward an email

[kdybicz]

Useful option to help preserve potentially important information.

Option not viable at this point in time, as enabling sending emails would require manual steps in form of Requesting production access to the SES service. Without it, the main blocker for using it widely is:

• You can only send mail to verified email addresses and domains, or to the Amazon SES mailbox simulator.
