           Summary: IMAP access often very slow or hangs
           Product: kmail2
           Version: 4.8
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: folders
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: aaronw at doofus.org


Version:           4.8 (using KDE 4.8.0) 
OS:                Linux

Often when trying to read my email which is stored on an IMAP server (Microsoft
Online Services) I run into problems where KMail will just hang saying
"Retrieving Folder Contents  Please wait..."

Fairly often KMail will take many seconds to complete the operation and in some
cases KMail will hang and never recover. Even clicking on a different email
does not make it recover, even if it was previously opened.

I am also using several filters on incoming email to move emails from various
mailing lists into folders.

I do not have any problems when using Thunderbird connected to the same server.

When it hangs I typically need to restart Akonadi in order to recover.

Note that I have a fair number of emails in several IMAP folders. My inbox has
about 7300 emails and my largest subfolder has 33,967 emails (8862 unread).

Reproducible: Sometimes

Steps to Reproduce:
Click on various emails until it hangs.

Actual Results:  
KMail will frequently be very slow to open the email and will periodically hang
completely and not recover.

Expected Results:  
It should open and read emails in a reasonable amount of time (a second or two
at the most).

OS: Linux (x86_64) release 3.1.0-1.2-desktop
Compiler: gcc
