More mail header options for managesieve

[counterpoint]

This has been asked before, but I think the only answers are now out of date. The question is how to extend the drop down in the managesieve rule configurator beyond the existing list of To, From, Subject, Body, Size, Current Date. (There is also ... but I don't understand what that is).

That "..." is what you need. There you can put any header name.
