a fresh user account on KDE 4.8.2, IMAP Resource created and successfully synchronized with Server. All mail there, all subfolder there, fine. Created a filter rule for the account to filter mailing lists into the subfolder. After a restart of KMAIL2 the rule worked, and filters the the mailing lists into a subfolder. But: All new mail in the incoming folder is now corrupted! Only the From, to and subject is displayed, see attachment 1 [details]. This corrupted mail is synced back to the IMAP server, see attachment 2 [details]. I verified by sending a mail to the affected account, content was removed as well. Mail marked as 'read' is obviously not affected. This is really a severe problem...please help! Reproducible: Always Steps to Reproduce: 1. start KMAIL 2. get new mail 3. Actual Results: See above
Created attachment 70499 [details] The way new mail is received
Created attachment 70500 [details] and how it is synced back (means corrupts the mail on the IMAP server as well)
What is you filter rule ?
If subject = [a word] move file to folder yxz Additionally Bogofilter Spam filter is configured
After disabling all *all* filter rules - including Spam-Filter - mail is *not* corrupted any longer. BTW, is it possible that the systems needs to be rebooted to recognize deleted filter rules? 'Just' a logout did not help....
The mails appear but with an empty body. No text, nothing. Checking on the server via webmail confirms the deletion of the text by kmail.
