FW: Insert artificial delay into IMAP server responses (to workaround OL2002)

I should have said that Outlook is too slow. The problem here is definitely
not with Cyrus, I was just hoping for a workaround in Cyrus to compensate
for Outlook's problem.

Here is a thread from a NG between a couple of people suffering from this
problem, and a tech at MS that is working to resolve the problem:

bvCHA.1624%40TK2MSFTNGP10&rnum=1&prev=/groups%3Fhl%3Den%26lr%3D%26ie%3DUTF-8
%26oe%3DUTF-8%26selm%3D%2523NarMtbvCHA.1624%2540TK2MSFTNGP10

After re-reading the post, I see that the admin did not insert a delay, he
put an artificial load on the server to slow it down. This resolved the
problem, but introduced/revealed other problems...

I have exchanged emails with the MS tech, and he requested details of my
setup, which I sent. However, I'm not expecting any resolution from them
anytime soon, as it seems this problem has existed in the OL family of
products ever since OL98.

I wouldn't even know where to begin with these files, as my programming
skills are close to nil. I was hoping for some parameter in a conf file
like:

KludgyOutlookIMAPHack = 1   #Compensates for MS's faulty IMAP client code by
adding delay to responses

But it sounds like there aren't too many people using the Cyrus/Outlook
combination, or you probably would have heard of this problem sooner.

The workaround may just be to use POP until MS fixes their IMAP code...
