Adding "ReplyTo"

[Taidgheen]

Many spam emails have a different ReplyTo which is the scammers actual email address eg:
From: [e-mail]
ReplyTo: [e-mail]

Even though the spoofed [e-mail] can often be important the scammers actual email [e-mail] can be more important.

Even if the "From" is a genuine email such as [e-mail], the scammer will have a different ReplyTo as the senders mail will get shut down for spamming.

In practice, the victim of a scam may only research the email address after they have already been emailing the scammer. That is why the ReplyTo is often important.
