New column "Sender[@]" part of AddOn or built-in?

[pstover]

I have seen a (new) column "Sender[@]" which shows the email address of the sender rather than his name.

Is this new column only available through an AddOn or is it built-in in Thunderbird?

Since which version is it part of the available columns?

I think it's due to this add-on: https://addons.mozilla.org/en-US/thunde ... ress-only/

[pstover]

yes, that's it

Thank you
