Doesn't seem to be working

I really appreciate how quickly this was put together. However, the latest update doesn’t seem to be working. Activity Monitor shows that Spamsieve (but only Spamsieve, not the helper) is active, but it is not accessible from Apple Mail, and all messages are being diverted to the spam folder.

It sounds like you need to install the Apple Mail plug-in. Please see this page.

Yes, this sorted it – although it was a bit more convoluted. The Terminal command wouldn’t work, so I had to reveal the app dock icon, install the plugin and reboot.

But it’s fixed – so thanks very much!
