Description of problem: I can open kmail and it shows the inbox having 2 emails received yesterday. I then close it and start the program again and it now shows I have > 100 emails received yesterday. Every time I open kmail, the number of emails in my inbox varies. Version-Release number of selected component (if applicable): kdepim-3.5.6-0.2.fc6 Additional info: kdepim-3.5.5 had the same problem I think, but it seems to be getting worse. I wonder if the timeout is too short when doing imap sync and it skips emails when imap server is somewhat slow.
I think a buggy IMAP server was causing this. I think it could do a better job of reporting issues with IMAP servers and be more robust in this department. But I will close this issue since it was largely external to kmail.
