geek678 I added SOGoMailAddOutgoingAddresses=YES to /opt/mailcow-dockerized/data/conf/sogo/sogo.conf but has no effect on the SOGo user ui : Preferences > Mail > General > When sending mail, add unknown recipients
geek678 I’m running 2023-10a the problem was with an account that enabled the option then disabled it before we set SOGoMailAddOutgoingAddresses=YES it works well with new accounts and accounts that did not change their default preferences
