Using hyperlinks in rmessage body

[Hall]

Is there a way to have a selected text in my message body have a hyperlink
using an http address? Fo example, my message has the word "pizza" and I
want clicking on pizza to open the browser to Domino Pizza's web site.

I don't mind if the message body format is html or rich-text.

When I did this in a message in html format, the text had a link when viewed
with Preview but when I opened the message, the hyperlink didn't work (mouse
didn't become a finger pointer and clicking did nothing).

Thanks!
