This should be an easy one :) - email notifications

During the initial setup of TKL you're asked for your passwords & email notifications address. The email notification address was missed so now I want to set it post setup.

Had a search but not found a definitive answer, this is the alerts I'm talking about /docs/automatic-security-alerts

I've gone into the Webmin and created an email address alias for root pointing to my email address (I copied from another vm I run) - will this work or is there more to it?

Can the initial setup be run again post setup to change these parameters?

Thanks

Donald
