Restore Receiver As Sender
A maskwire tool to always restore the original receiver of a message as the sender when replying on it
What does this do?
Assume you have email addresses that you use for specific services, for example [email protected], or Fastmails Masked Emails.
If you receive an email onto this address and hit "reply", maskwire will rewrite the sender that is used to send the message back to "[email protected]"
The result is, that all messages will be sent from whatever received them in the first place.
What does this do exactly?
Maskwire will inject a custom "Reply-to" header into the message, that is the long reply-to address that starts with a "🎭" emoji

When hitting reply, your email (should) draft a new message to the reply-to address which is the maskwire injected one. Sending an email to this address is telling maskwire that you want to restore the original receiver of this email back as sender.
