Hallo, Platonides,

Kind of. If the spammer uses a proxy, and the proxy
provides a
X-Forwarded-For header, with the IP of the client on behalf of which
it is forwarding the request (or more, if there were several proxy
hops), MediaWiki will use that IP instead, provided it trusts the
proxy. Your apache access_log will report the proxy in such case.
This is most interesting for the case where you have a
reverse proxy
(such as squid or varnish) in front of your site.
A proxy is considered trusted if its ip appears on
$wgSquidServers or
$wgSquidServersNoPurge.
Thank you - I'll ask my provider. Now I know what to ask him ...
Viele Gruesse!
