The other problem is it involves adding computational infrastructure to 
correct minor user-error behaviors, which (as a sometimes educator) I'm 
opposed to philosophically.  The MUA I use (Thunderbird) even includes a 
"Reply List" button to prevent this.  Thanks for that response.  It's 
very clear to me that I *don't* want this feature.  FastMail is a 
completely different use case, but I'm not sure I would turn it on 
there, either.

So, presumably if I use

    duplicatesuppression: 0

Then the duplicate_db skiplist won't even be created in the first place?
