Forward Mail to multiple Chat/GroupIDs + readme.md update

[phant]

Hint: python3-python-telegram-bot could be available with Bullseye (Testing, 25th of May 2012)

Maybe 2022 ?

forward_to_chat_id: <Chat/User ID>

Only one Chat or User ID possible ?

Thanks for that note, readme was updated as python3-python-telegram-bot is part of Debian Bullseye.

Yes for now only one Chat/UserID per agent is supported. Just tagged this issue as enhancement to check multi target for upcomming releases.
