At first glance, it looks to me as if nginx is doing exactly what you
told it to. I suspect that a small reconfiguration of mailman will work
for you.

The configuration shows that "/" is (externally) rewritten to
/mailman/listinfo, which is why that appears in the browser bar.

The browser then makes a fresh request for /mailman/listinfo, which is
handled by your location /mailman/ {} block, where fastcgi_split_path_info
sets $fastcgi_script_name to "/mailman/listinfo", and $fastcgi_path_info to
"", and things work. Presumably the fastcgi server is able to process
the file /usr/lib/cgi-bin/mailman/listinfo.

Here, /listinfo is handled by the location / {} block, which does a
rewrite (internally) to /mailman/listinfo, which is handled the same as
in the previous case, and things work.

Analogous to /listinfo, internal rewrite to /mailman/admin,
$fastcgi_script_name is "/mailman/admin", $fastcgi_path_info is "",
things work.

The first two have separate location blocks; the third is similar to
the redirected initial request above.

Same as /listinfo case, handled by the location / {} block, internal
rewrite to /mailman/cgi-bin/mailman/listinfo, $fastcgi_script_name is
"/mailman/cgi-bin", $fastcgi_path_info is "/mailman/listinfo", and
things don't work on the fastcgi server because it can't find the file
to process. There probably is no file /usr/lib/cgi-bin/mailman/cgi-bin.

To make things work for you, you could probably try a new "location
/cgi-bin/ {}" block which rewrites to the same url without the "/cgi-bin"
at the start.

But it seems more sensible to just...

....remove the string "/cgi-bin" from two lines up there. (And you could
probably even remove the "/mailman" too.) Your nginx is not configured
to serve from the /cgi-bin urls, but is from the others.

(Note: I haven't tested any of this.)

The page http://wiki.nginx.org/Mailman suggests to configure mailman by
following a separate website. Possibly the information has gotten out
of sync.

Good luck with it,
