Gnus not selecting `from' address after upgrade

[Paul Bibbings]

Hello

Can anyone suggest why the following:

    (setq gnus-posting-styles
     '(("^nnml.*one"
         (name "Paul Bibbings")
         (address "paul.bibbings@one.net"))
       ("^nnml.*two"
         (name "Paul Bibbings")
         (address "paul.bibbings@two.com"))
       ("^nnml.*three"
         (name "Paul Bibbings")
         (address "paul.bibbings@three.com"))
       (".*"
         (name "Paul Bibbings")
         (address "paul.bibbings@default.com"))))

with the following groups:

     nnml+mailbox:one
     nnml+mailbox:two
     nnml+mailbox:three

might have become broken after an upgrade of gnus?

   No Gnus v0.11
   GNU Emacs 23.1.1 (i386-mingw-nt6.0.6002) of 2009-07-30 on SOFT-MJASON

This used to work, but now everything shoots through to the default and,
as I have a configuration that selects the smtp server based on the from
name, much is going awry! :(

Is it possible that this was just wrong in the first place and merely
worked on a quirk?  (IIRC, I merely adjusted this code from something
that I snaffled from the internet.)

Regards, and thank you
