Well when I moused over the e-mail addresses it showed a yahoo mail type link in the lower left of my browser.

I use the e-mail riddler myself yes, I have it on every page for the contact me link, and post it in certain articles as well.

It brings up my default e-mail, which for me is Outlook also. With help from the folks here I also set it up to auto populate a message and my phone numbers into the body of the message.
