I added @beta.toadworld.com to my Safe Senders list just now (because I'd rather get these emails the same day. They've been getting stuck because of our firewall, and I get them a day late).
Here are the steps I took - I'm also testing adding an image to a post.
In the Forum (online), I'm using the 'Paste from Word' button on the toolbar.
That worked for the content, but not for the image I copied, so I used the first 'Insert/Edit Media' button (there are two).
In Outlook (2007):
Go to **Tools | Options | Preferences - Junk E-mail | Option - Safe Senders**
Click Add and type @beta.toadworld.com
Click **OK** (of course).
