I changed my .gnus file following your instructions. As you see in the
quoting header, I wasn't successful.
The message package manual is not very enlightening in this case.
I insert the  lines from my .gnus:

(setq message-insert-formatted-citation-line
   '(message-citation-line-format
       "on %d. %m. %Y at %X %n <%a> wrote:"))

"%n" should mean "name" and "<%a>" should mean "mail address". I took
this from the syntax used by Mutt. I guess it is different in Gnus?
