When sending mail from shell, e.g.,
echo '123' | mail -s 'subject' name@mail.com
The recipient gets an email from "my-local-username@my-machine-name.local", e.g., "bob@macbook.local"
How can I change this to an email address of my choosing?
Change “from” address in Terminal `mail`
command lineemailterminal

Tack an escape to the end of your mail command to pass a header to sendmail.
See this answer and others that use the -- terminator to tell the mail program those arguments are for the next program.
