I have set up my kopano-server with Postfix so that email inboxes are sourced from /etc/postfix/virtual, which looks like this:
email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org
Receiving emails on these virtual inboxes works well and they are delivered to my kopano account called “user”. What I am struggling with now is what I have to do in order to be able to send emails / reply to emails sent to these virtual inboxes from within my user’s account (in WebApp, DeskApp and from my iPhone).
The only solution I can think of would include setting up accounts on kopano for all these virtual recipients and then configure the WebApp in settings / send as. Is that the right thing to do, i.e. will this achieve what I want to do here?
Next step is to then set up fetchmail to retrieve mail from external servers. Does that have any implications on what I want to do here?
