I mostly agree with the latter remark, but when using server side  
filtering, I can imagine that people revert to this. It is a PITA that  
one has to add each folder where messages are filtered into to the  
list of folders that are checked for new mail.

It has happened to me several times already that after adding a new  
filter I forgot to do this and only after a while found out that lots  
of unread messages where filtered in folders that are not scanned for  
new messages.
