Some time ago I was trying to send root mail to an isp smtp mail.m.mynet.net.au. I have succeeded in sending the email when doing a test, but I get the following error. 553 sorry, your envelope sender domain must exist (#5.7.1) The domain of the machine is localhost.localdomain. I want only to be able to send email (to my email address and a work address) logs to myname@xxxxxxxxxxxxx I do not want to receive mail only send root mail and log files. Is there a simple way of doing this. I have had assistance previously which helped a lot.
