Akismet has lost it’s mind over the past several weeks or so.

Lack of whitelisting (as you discovered) is one of several pitfalls of using a remote service.

You could look at how my skip-akismet plugin works and check when $_POST contains submitted $_POST – if ‘post_content’ has only those whitelisted domains, you can unhook akismet as I do for mods, etc.

There’s also another possibly I have been considering – only send to akismet the first few dozen posts by any new member. After that many they’ve probably met with your approval and any other moderation should be done manually, not automatically.
