Problems with imap and davmail

[Mario Peter <empee0@googlemail.com>]

Hi everybody,

after 10 years of happly using gnus in our firm i'm now forced to use
davmail to get imap access to our exchange server :-(( . Unfortunally
it seems not to be as so easy as I thought, all try's to get an active
list of the mailbox get failed. My setup is quite simple (gnus is
recent from git)  :
------
(setq  gnus-secondary-select-methods
      '( ....
        (nnimap "localhost"
                (nnimap-server-address "localhost")
                (nnimap-server-port 1143))
      ....
------
I get authenticated without problems:

----
* OK [CAPABILITY IMAP4REV1 AUTH=LOGIN] IMAP4rev1 DavMail server ready
9 NOOP
9 BAD command authentication required
10 LOGIN "user" "pass"
10 OK Authenticated
11 NOOP
11 OK NOOP completed
-----

thats all. other imap accounts start at this point with LIST "" "*%"
.   The nnimap output is as follows:
-----
======================================================================
1 -> nnimap-server-opened: server="localhost"
1 <- nnimap-server-opened: t
======================================================================
1 -> nnimap-request-list: server="localhost"
| 2 -> nnimap-possibly-change-server: server="localhost"
| 2 <- nnimap-possibly-change-server: " *nnimap* localhost"
| 2 -> nnimap-before-find-minmax-bugworkaround:
| 2 <- nnimap-before-find-minmax-bugworkaround: t
| 2 -> nnimap-pattern-to-list-arguments: pattern="*"
| 2 <- nnimap-pattern-to-list-arguments: ((nil . "*"))
---

And here is what gnus says when entering the server in server buffer
(look at the 'agent-min' value for imap-mailbox-put...):
-----
Debugger entered--Lisp error:

The davmail setup seems to be ok, because thunderbird works perfectly.

Is there any idea what goes wrong here?  Thanks in advance for looking
on this !!!!!
