I am thinking about the future of EXT:powermail and howto deal with the massive configuration array aka TypoScript constants and setup.
I am tired of all the "undefined array key warnings" in php8. If the extension is well configured, it works quite well now. The code is not very clean, with all these workarounds. And in case an integrator removes a whole configuration branch, it will lead to many exceptions. (1/2)
