How to make mutt save emails when sent from terminal?

Question

bash

Good day to all.
There is a configured mutt. When working with mail from the program itself, everything is fine. But, if you send a letter from the terminal, then it is not saved in Sent. How can you overcome?
I send it like this:
echo "Test" | mutt -s "test" [email protected]
Config mutt.

Answer 1

In .mutt/set add an option
set copy = yes
