Hello, I send mails with the next command: #mutt -x -i /tmp/mail -e 'my_hdr Reply-To: dir@xxxxx <dir@xxxxx>' -s'Prueba' pepe@xxxxxx < . and the "reply to" of the mail is "dir@xxxxx". I would like that when the direction of which send the mail is incorrect, to be able to indicate the answer direction of which send the error message that send the server. It is possible? Thanks
