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?
Why the z-spelling over s-spelling? I thought the z-spelling was purely a North America thing. (personally I always try to use the s-spelling.)
This is maybe more clear/correct: "Rich media is cached without the TTL, but the rich media may have an image which can expire, like AWS-signed URL."
I wonder how much sense it makes to capitalise package names here. Backticks generally mean code. So I think it should either be the package name like how you'd use it in a command (pacman -S postgresql), or not be between backticks. For packages I think it make sense to use backticks and the names like how you'd use in commands.
