how-to white list our e-mail address with Yahoo's e-mail service
Scroll down this page to see how to white list our e-mail address when using Yahoo's e-mail service.

After you log in to your Yahoo account, click on the "Options" button located on the right-hand side of the page near the top.

Now, click on the "Filters" link that will be on the page now shown.

Next, click on the "Add" button.

You'll now see four rows of drop down menus with empty fields next to them.
We are only interested in the "From header" row.
For that row, make sure that "contains" is chosen for the drop-down menu list (it is by default) and then enter our e-mail address in the empty field next to it.
For the drop-down menu near the bottom of the screen, select "Inbox".

After you have done that, click on the "Add Filter" button located near the bottom of the screen on the left hand side.
You will then have "white listed" our e-mail address, and all of our future messages should go straight to your inbox (your main Yahoo e-mail folder).
