I copy a local folder in my imap account.
In my webmail account i see the folder is created and filled with all messages. Good.
I copy another local folder in my imap account.
In my webmail account i see the folder is created and not filled with its messages!


In the two cases the messages are old and tagged as read.

Where is problem?

Note:
my webmail account is a zimbra account at my ISP

i wait for one day. no sync.

Today i move mails with today date to the second folder in my imap account then they were all synced!

How to force sync from kmail to webmail of the old mails?

Thanks
