Although I use the basic POP3 approach, I was in that same position a 
few months ago because of the "Retrieving folder contents' hangup, so 
migrated to Thunderbird, although still checking with Kmail in the hope 
it would improve.

Since then a massive KDE Plasma5 update seems to have removed the 
'Retrieving folder contents' hangup, and all seems well again - though 
still with frequent duplicate emails (which I suspect is also to do with 
filtering into subfolders).

But having found Thunderbird such a reliable and slick performer 
(albeit with a truly generally awful application interface) I am having 
difficulty persuading myself to return to Kmail.
  (An additional benefit with Thunderbird is that the whole thing is 
contained in one folder (~/.thunderbird), making it a simple matter to 
clone to another machine.)
