Thanks. Sadly, it doesn't really provide any clues (I assume that you also tested with MailFollowUp moved out of ~/Library/Mail/Bundles/). All I can say is try to disable/enable some options...

The default setting of QF will regard any line with (at least) two hyphens as a signature separator, which—as you already found—may be a bit too liberal for some e-mails....

I was actually considering installing Big Sur, after having skipped Catalina, but I keep reading about BS bricking Late 2013 MBP's, which I happen to have. So not feeling very...

Can you provide a bit more information? I don't see any trailing whitespace when using `${message.from}` myself, so it may be a specific use that could be causing the problem...

Right, I see the problem too. The actual problem is because caused by an escaping issue, you can probably solve it (temporarily, as this needs to get fixed nonetheless) by...

@gravesit sounds like #31 is causing more problems than just with the custom signature separator, so I'll look at that ASAP.

I'm not running High Sierra anymore, but I used QF myself on it extensively, and it worked acceptably. Not sure why specifically the quote fixing isn't working.

Yes, I believe this is a known issue with Catalina (and probably Big Sur). I'm still running Mojave so can't debug or fix :(
