Problem you are trying to solve

When I want to forward multiple mails to one receiver as attachment, I have to do it for each mail and can't select all messages I want to send at once.

Maybe it goes against design decisions? Because multiple attachments can interfer easier with possible upload limits for example.

I would be happy to take implementation, if its a possible good first issue. I'm a java dev but android not so much.

Suggested solution

After selecting multiple message, I also have the option to forward in "..." context menu.
At the moment "Forward" only appears in the "..." context menu, when I select only one mail.

No response

Start by locating the message-selection overflow menu and the existing single-message Forward action in the Android app. Trace how one message is converted into an attachment, then determine the behavior for multiple selected messages. Done means selecting multiple messages exposes Forward and sends them together as attachments.
