Oh, this is good to know! I haven't encountered this issue personally yet, but maybe once I've updated my mailserver, I won't encounter it in the future.
Now to figure out how to stop the same thing happening in SMS.
If you're texting with an iOS user and they use a reaction, Apple "helpfully" forwards the reaction as text. Which is OK. What I don't like is that it also quotes the complete text that the person reacted to.
True. There's no solution to this that appeals to everyone. Personally, it wouldn't bother me at all to not know which message got "liked" (because "liking" something doesn't really say anything that important), but I can see how it could be important to others.
