I have a question regarding aliases in Mailcow. It looks like email addresses included as “Goto addresses” in Mailcow UI alias definition can also send emails on behalf of the alias. It is possible to remove visibility of the alias in SOGo, but it is (probably, haven’t checked it) possible to use some mail client to send emails using that alias as From by email accounts included in the alias list.
Hence the question: is it possible to define alias that is used just to receive emails and cannot be used to send them? If it is possible, how can I do that?
