help with getting Wanderlust to connect to my IMAP server

[Kevin Buchs <buchs.kevin@mayo.edu>]

I was really hoping I could get an IMAP email client running in emacs. I'm
stuck with Wanderlust failing to connect to my server. It doesn't even
prompt for my password any longer. I get a message back: "Cannot open:
elmo-network-initialize-session". I've tried both the configuration of
the default options in ~/.wl and a plain folder in ~/.folders as well
as a more deluxe folder entry in ~/.folders.

I've configured other email clients, like Thunderbird, to work with my
server, a MS Exchange IMAP-protocol host.

Any suggestions or pointers to further documentation would be appreciated.

My user name on the IMAP server is not my email address. I substituted 
the string "user123" for it below. My server has been replaced with the 
string "server123":

Here is what I have at this point in .wl

(setq wl-icon-directory "~/.emacs.d/el-get/wanderlust/icons")
(setq wl-smtp-connection-type 'starttls
      wl-smtp-posting-port 587
      wl-smtp-authenticate-type "login"
      wl-smtp-posting-user "user123"
      wl-smtp-posting-server "server123"
(setq wl-from "Kevin Buchs <buchs.kevin@mayo.edu>")
(setq wl-user-mail-address-list
      (list (wl-address-header-extract-address wl-from) wl-from))
(setq
      wl-fcc-force-as-read    t
      wl-default-spec "%")


Here is what I have in .folders

%inbox:user123/login@server123:993
