Change the “From:” address in Unix “mail”

Question

Sending a message from the Unix command line using mail TO_ADDR results in an email from $USER@$HOSTNAME. Is there a way to change the \"From:\" ad

Answer 1

Here are some options:

• If you have privelige enough, configure sendmail to do rewrites with the generics table

• Write the entire header yourself (or mail it to yourself, save the entire message with all headers, and re-edit, and send it with rmail from the command line

• Send directly with sendmail, use the "-f" command line flag and don't include your "From:" line in your message

These aren't all exactly the same, but I'll leave it to you look into it further.

On my portable, I have sendmail authenticating as a client to an outgoing mail server and I use generics to make returning mail come to another account. It works like a charm. I aggregate incoming mail with fetchmail.
