Again, `gnus-sorted-header-list' is only relevant for article buffers
(reading mail), not message-mode buffers (writing mail).

Yeah, you didn't want to generate them beforehand.

Hm, not sure.  I'd expected to be queried only for (optional . Foo)
entries, but I've never customized anything here.

BTW, why do you want Cc and Bcc to show up everytime?  Do you really
need to Cc and Bcc different people in each and every mail?

Most probably, you really want to use posting styles again.  That way,
you could define that when mailing from all of your uni groups, a Cc
header with value your-prof@your-uni.de will be inserted or something
along these lines.

The sorting *is* correct in *article* buffers, cause that's what you've
customized.

Yeah, it specifies what extra variable Gnus should store in its overview
files.  For example, if you'd want to display the contents of the
X-Foobar header in your summary, then you'd need that to be in
`gnus-extra-headers', because else Gnus would have to fetch any article
in order to get that header in order to display it in summary.  Clearly,
that wouldn't scale if a summary contains thousands of messages.
