I'm using mail and postfix to send and receive messages. When I use the command below the email is not sent.
My linux is ubuntu 18:
mail -s "Test" -A /opt/bin/anexo.txt xxxxxx@hotmail.com < /opt/bin/arquivo.txt
I can send only with an attachment or just with the body of the message, but not both at the same time. Please, can someone help me?
