[MlMt] Download Images still downloads 1 pixel ones

What I did was add a list of tracker sites to pf.conf, e.g.:

```
block drop from any to t.paypal.com
block drop from any to epl.paypal-communication.com
block drop from any to iqconnect.lmhostediq.com
block drop from any to doodle-2b4fcd38ea57.intercom-mail.com
block drop from any to intercom-mail.com
block drop from any to links.forwardcdn.com
```

But I still want to make a MM command that will take a new address and 
stuff it into a list to block.
