There's something off about this sentence 🤔. It's similar to the setting above[1], so should probably be more like "list of TLDs (top-level domains) which will be ignored by the metadata parser."
This sentence seems weird too. Maybe "Enable sending emails from your instance." or something?
Here we go to lowercase for the name of a software, I'm wondering what the reasoning is. I see on their site that they also write it with lowercase[1], so I assume that's the reason why we also lowercase it here?
Map.get/3 doesn't work in this case. The key can contain nil. So in that case the description would be nil instead of an empty string (and the rest of the code expects a string).
i…Note: This test broke with removing the filename from this field. But this is not what it tests, and as afaict it doesn't even actually tests what it's supposed to do. Therefore I decided to just remove it instead of leaving it in what seems to be a broken state.
