I‘m using a domain with a single mailbox and a catch all alias.
Sometimes, I need to answer with one of the used aliases.
At the moment, I create a explicit alias for that purpose, select it in SoGo and send the mail.
But is it possible to disable to from address check in SoGo and allow all?
If I modify the from address, the sending button is greyed out. It still works, but use the default/main name (in my case info@domain)
