TYPO3 Powermail and Powermail Conditions

Build only the requested form change. Obtain the installed Core/PHP versions, both package sources and lock references, form UID, field markers, language, mail transport and expected visibility rules before choosing examples. Preserve existing forms, recipient routing and data.

This independently maintained guide documents their work and the separate webconsulting forks; it does not transfer their GPL-2.0-or-later source code into this guide's licence.
