Akismet wipes the comment spam queue every 15 days. This snippet changes the interval to daily, forcing Akismet to delete all spam messages every 2 days rather than every 15 days.
Go to theme's folder and find the file functions.php - that's where you put all your custom functions.
[code] add_filter( 'akismet_delete_comment_interval', 'custom_set_delete_interval' );function custom_set_delete_interval() {
return 2;
}
[/code]
Save the functions.php file and then check that it works - go to http://your-site.com/wp-admin/admin.php?page=akismet-key-config and scroll down to where you can set options. You'll see it say "Note: Spam in the spam folder older than 2 days is deleted automatically."
