They're not, but that doesn't mean you can't get them...

Here's a snippet from my gnus-posting-styles that should give you an
idea of how to do what you want:

    (gnus-article-reply
     (signature-file
      (let* ((net
              (save-excursion
                (set-buffer gnus-article-buffer)
                (car
                 (cdr
                  (mail-extract-address-components
                   (message-fetch-field
                    "From"))))))
             (rec (car (bbdb-search
                        (bbdb-records) nil nil
                        net nil nil)))
             (sig (if rec
                      (bbdb-record-getprop
                       rec 'signature))))
        (cond (sig sig)
              ((string-match "@.*\\.?mitre\\.org" net)
               "~/.signature-mitre-i")
              ((string-match "nnml:personal.*"
                              gnus-newsgroup-name)
               "~/.signature-personal")
              (t "~/.signature-mitre"))))

What does it do?  If the message is a reply (that's the
gnus-article-reply part), set signature file in a particular way.  It
goes to the article buffer and gets the From line (who I'm replying
to; I ignore Reply-To for this purpose; haven't been burned yet, but I
know it will happen :-)  Then I look for that person in my bbdb.  If I
find her, I look for a signature-file record in bbdb.  If there is one
I use it, otherwise I set signature file based on whether the person
is someone I work with or if the gnusgroup is one I use for non-work
mail and finally, if all else fails, I put my work address in the
sig.  I do have to change that last one by hand occasionally, but
haven't come up with a perfect formula for determining it otherwise.

Hope this helps,
