Subject: IMAP addon ofr Win95 Exchange

Is there anywhere an IMAP addon for Win95 Exchange ? I would like to use Win95
Exchange as an IMAP client to connect to our test IMAP server imapd.
TIA

IMAP is not within Exchange's scheme of things.  

Exchange bases its operations on storing mail locally (like POP3 
allows).  IMAP requires that mail remains on the server.  On that mail 
server the IMAP client can make their own folders etc but they remain on 
the server.

Exchange creators pride themselves on that universal Inbox, and IMAP just 
does not work with that logic.  Now if they did an IMAP client that added 
other folders besides the user's personal folders (like the shared 
folders on an MS Mail server) then maybe I can see it.  Which reminds me; 
didn't Microsoft make an Exchange client that allowed viewing of shared 
folders on an MS Mail server?

IMAP doesn't have any such requirement.  It can be used to download
mail to a local folder just like POP3 can.  IMAP does allow the option
of keeping mail on the server, which is more problematic with POP3.

Some preliminary investigation has been done by the e-mail group at
UW.  On the surface it looks feasible to write an IMAP <-> MAPI
interface.  We will be investigating it further after the Pine 3.92
release...

Exchange lets you have multiple mail stores...

>folders on an MS Mail server?

You can indeed have multiple mail stores, local and remote, and
multiple inboxes, with exchange.  There is indeed a plug-in that lets
you access folders on remote MS-Mail servers.

An IMAP plug-in is theoretically possible.  We just need to find
a programmer who cares about both IMAP and Exchange -- in my
experience, folks who care about one tend not to care about the other.

We would be very interested in this work. Could you post any progress please?

No.

At least some of the relevant Microsoft folks seem to be unaware that
IMAP even exists. We've passed on the relevant RFCs. 

If Microsoft starts supporting IMAP, there will be joy throughout the 
land, because this will legitimize the standard and convince people who 
know what they're doing to support IMAP as well.

No, but my WinBiff program will at least get the IMAP headers;
it works just fine under Win95.

Look at http://www.tucows.com/files/wnbff33.zip.

I'm not sure this is strictly accurate. The Exchange model appears to allow
not only alternative transport providers, but also an alternative message store
provider, and indeed an alternative address book provider. I would have thought
that the universal Inbox could still be used for incoming messages, and then an
IMAP store provider could allow access to a central store for storage. This is
presumably analagous to the difference between using local folders and using 
an Exchange server (whenever!).

Lots of coding of course......
