I just did a "cvs update" in trunk. First off, I get the following
message
byte-code: Error in ~/.gnus: Please use `smtpmail.el' bundled with Emacs.
as smtpmail.el got restored in the contrib directory when I did the cvs
update.
But other than that, Gnus now starts up fine with no need to set
imap-enable-exchange-bug-workaround to t.
Thanks,
Bjorn.
