Each of my systems sends alerts to my mail server for delivery to my email address through a special user account on my mail server with no shell account which is only used for this purpose. Can I limit all mail sent by authenticating through this user account so that it can only be delivered to my email address? The user's password is stored in plain text in ssmtp.conf on each of my systems but I figure that doesn't matter if it can only be used to send mail to my address.
