This is my first post, please be gentle :) I have sendmail set up on Ubuntu 18.04. I use a remote relay to send mail (mail.noip.com 587). Mail sends out ok from command line. I have two webmail addresses attached to my server. How do you get server notification emails (fail2ban, cron etc) to leave a copy on my webmail addresses, they are delivered locally ok but I am not sure how to get them on my relay server web address's?
Thanks in advance
