At the bottom of my html email I have my address, web address and email address as html text. The web address and email address are links. When I view the links in Apple Mail the link to the website is obvious - the curser turns to the hand icon and the text changes color - but when I move the curser over the link to the email address it doesn't change to the hand icon or change color. It can be clicked, but nothing visual happens to denote that it is a link.

I've changed the email address, to one other than my own, but this makes no difference.

I've just relooked at this. Weirdly the first time I open the email the curser and text color on the link changes, but not after the first open.
