I am using the labelling / tagging (I do not know the exact translation, it's "Schlagwörter" in German) of Thunderbird to filter my mails.
When I reply to an email or forward it, I would like to have the sent message, stored in my Sent folder, labelled with the same tags/labels as the original incoming message.
Is that somehow possible?
As an alternative, I thought about a filter condition like "Messages that are replies to messages that are labelled like xyz", but I could not find that as well.
