A need has arisen here recently for me to need to “change” the headers on an email, so I can tell two people at work apart. Both have their name in the email header the same. Let’s call them “John Doe.” So in order to tell them apart, I’ve added a reverse alias rule to mutt to handle this. First enable the use of them by using
Then set up the alias. This can be added to your alias file, or straight into your .muttrc
alias fake_john firstname.lastname@example.org (Fake John Doe)
Now all mail that comes in from email@example.com will show up as from “Fake John Doe” but the headers will remain the same, and no one is the wiser.
