Just wanted to throw this out there, has there been any talk of using Sogo instead of roundcube/nextcloud? Cloudron uses it for their mail solution and they preconfigure it with email addresses you create in the admin interface. The only thing I see as a problem with (I don’t know anything about the backend / intergration) is that the UI doesn’t seem to support adding aliases like roundcude does. But it would be super cool if the aliases you make in the Miab admin area get preconfigured into Sogo. (Already has a dropdown selection for the from address, but only currently for multiple user accounts not aliases.)
I saw some folks mentioning it in other posts but figured I would make a dedicated topic. Thanks!
