Specify the from user when sending email using the mail command

You can specify any extra header you may need with -a

$mail -s "Some random subject" -a "From: some@mail.tld" to@mail.tld

linux email redhat

Essentially:

echo "This is the main body of the mail" | mail -s "Subject of the Email" recipent_address@example.com -- -f from_user@example.com

linux email redhat

mail -r from@from.from -R from@from.com

-r = from-addr-R = reply-to addr

The author has indicated his version of mail doesn't support this flag. But if you have a version that does this works fine.
