[ILUG] [not directly on topic] IMAP implementations

[David Ryan]

Does anyone know of any good books on IMAP implementations ?

My problem is that we have a server which is misbehaving (showing the
sender instead of the recipient in many users sent mail folders) and I need
to be able to tie down where the problem lies.

First instinct says it is a client displaying the incorrect column header,
but this is not the case.
Second instinct says it is the server sending out incorrect information,
but this also appears not to be the case since different clients give
different views (sender vs recipient) of the same folder, and at least one
of them gives the correct view.
Third instinct says it is either the server or the client not recognising
that the user who is requesting the folder information is the same user who
sent the mail.  Problem is that this issue does not appear to be covered in
the RFC, so it doesn't look like a server or client compliancy issue.

I have checked the RFC for IMAP and it gives no special status to any
folder other than INBOX

However, I *know* the various clients (and I have tried a lot) do work
correctly with many of the normal server implementations or else they
wouldn't be accepted.

So, here I am with a server which appears to comply with the RFC and with
clients which appear to work with other RFC compliant servers, but when the
two of them get together something goes wrong.

I have had a brief look at the O'Reilly site and it seems to have a book on
programming for IMAP which is not what I need.  I need a technical
discussion of the way in which clients and servers interact to see if it is
a server side problem or a client one.

Thanks,

David
