Dear Thunderbird Development Team and Community,
my suggestion is to add different outgoing mail servers for the mobile app like it is the case on Thunderbird Desktop. So one can have a different outgoing mail server for an alias address.
Connected to this, I would suggest to change the design of the "select outgoing mail address" dialog in the app to make it a bit more intuitive, but this is only a minor thing.
Thanks for this awesome app!
I love it!
