After I created a new folder with the web interface to my mail account (web.de), the new folder is not shown by kmail.  But it is shown when I select "Serverside Subscriptions" - grayed and with a selection marker, because I do not have serverside subscriptions enabled.  "Local Abonnements" does not show the new folder.

Reproducible: Always

Steps to Reproduce:
1. Create a new folder via the web interface on your IMAP account (with kmail/kontact it's not possible -see my other bug ... :(
2. Open kontact/kmail, right click on the IMAP account, select "Local Abonnements" and "Serverside Subscriptions"
3. compare the folders shown
Actual Results:  
see above

Expected Results:  
a new folder on the IMAP account not created via kmail shall be shown and accessible (selected by default) if "Serverside Subscription" is disabled and the whole mailbox/account in "Local Abonnements" is checkmarked.

I consider the bug major because I can not use my mail with KDE mail app.
Every major network service should be accessible with a KDE app, because KDE has still the best integration.  But as it goes the last few years since KDE 4,  I'm thinking more and more to switch...  Once upon a time, KDE had the highest quality upon all desktops, even compared to Mac and Windows.  What happened???
