You need to move the more general match "^nnimap\\+Fastmail:INBOX" to
the end of the list:

(setq gnus-parameters
      '(("^nnimap\\+Fastmail:INBOX\\.D-BARF$"
         (to-address . "D-BARF@yahoogroups.de")
         (subscribed . t)
         (gnus-use-scoring t)
         (gcc-self . "nnimap+Fastmail:INBOX.Sent Items"))
        ;; [...]
	("^nnimap\\+Fastmail:INBOX"
         (gnus-use-scoring nil)
         (gcc-self . t))))

> Soring is enabled for the two groups, so the matches should be correct.

The difference is that `gnus-use-scoring' is a group local variable,
whereas `gcc-self' is a group parameter (dotted list).  Surprisingly,
they behave different:

(setq gnus-parameters
      '(("^nnimap\\+.*:INBOX"
	 (tmp-variable 11)
	 (display . 11))
        ("^nnimap\\+.*:INBOX\\.test$"
	 (tmp-variable 22)
	 (display . 22))))

When I enter INBOX.test `M-: tmp-variable RET' returns 22 whereas 
`M-: (gnus-group-find-parameter gnus-newsgroup-name 'display) RET'
returns 11.

I think this inconsistent behavior should be fixed.  IMHO it would be
better if we choose the same behavior `gnus-posting-styles'.

Bye, Reiner.

I tried that, and then the gcc-self works correct. Unfortunately then
gnus-use-scoring in nil in D-BARF. So it seems the group parameters
(dotted lists) have to be set for the most strict match first to the
most general last.

Instead group local variables need to be set the other way round.

So I tried separating group parameters and group local variables
strictly:

,----[ C-h v gnus-parameters RET ]
| Value:
| (("^nnimap\\+Fastmail:INBOX\\.D-BARF$"
|   (to-address . "D-BARF@yahoogroups.de")
|   (subscribed . t)
|   (gcc-self . none))
|  ("^nnimap\\+Fastmail:INBOX\\.emms-patches$"
|   (to-address . "emms-patches@gnu.org")
|   (subscribed . t)
|   (gcc-self . none))
|  ("^nnimap\\+Fastmail:INBOX"
|   (gnus-use-scoring nil)
|   (gcc-self . t))
|  ("^nnimap\\+Fastmail:INBOX\\.D-BARF$"
|   (gnus-use-scoring t))
|  ("^nnimap\\+Fastmail:INBOX\\.emms-patches$"
|   (gnus-use-scoring t)
|   (gnus-thread-sort-functions
|    '(gnus-thread-sort-by-number gnus-thread-sort-by-total-score
|                                 (not gnus-thread-sort-by-date)))))

I did some short testing and it seems to work. :-)

Please do that.

Yes. That's exactly what I expected when I did my setup because the docs
don't tell a difference.

In my first try I only used `gnus-parameters' and mixed my posting
styles in with (posting-style ...) blocks. Of course it didn't work
properly. If it had the same behavior as the posting styles, it should
have worked.

Bye and thanks,
