Thanks to Ed (Head of Central Antispam) and Ryan (New Host), we now have a brand new host for our central antispam list. It's a separate host from the main site, so we might get better performance on the one or the other if not both ;)
Because it's a new server, you will need to do some small modifications to your b2evo installation if you want to take advantage of it.
Pick your easiest solution:
Solution 1
You're not in a hurry: just wait for the next 0.9.2 [Update: available now] or 1.8-alpha release and you'll be fine.
Solution 2
You care a lot about antispam, but not so much about pinging b2evo when you publish a new post.
Just go into your /conf/_advanced.php file, and at the end of the file replace this line:
$evonetsrv_host = 'b2evolution.net';
with this line:
$evonetsrv_host = 'antispam.b2evolution.net';
Solution 3
You're running version 0.9.1 and you want it all:
Go the end of your /conf/_advanced.php file, and add the following lines:
$antispamsrv_host = 'antispam.b2evolution.net';
$antispamsrv_port = 80;
$antispamsrv_uri = '/evonetsrv/xmlrpc.php';
Note the $antispamsrv prefix. It is different from the existing $evonetsrv lines.
Download this file and use it to replace your existing /b2evocore/_functions_antispam.php file. (If you have trouble with downloading the PHP file, you can get this ZIPped file instead).
CVS
Note: CVS servers are not up to date right now because SourceForge has had them down for the whole week... stay tuned.
Update: 0.9.2 is now up to date on CVS (look for the v-0-9-1 branch).
