I am using Kopano solely with db backend. So, I created a group via kopano-admin and gave it an e-mail address with the -e parameter. I would like to send emails to this mail address from outside. As I am using Postfix I think I need to have a virtual alias map as described here: https://kb.kopano.io/display/WIKI/Postfix. However, this example just works for normal user accounts but does not resolve distribution groups, or am I wrong? Does anyone know an appropriate sql query for resolving the members of a group? Or is there a different way to send mails to all members of a group?
Any hints are highly appreciated. Thanks!
