You are actually trying to do 2 things. The first thing is the automating the year part of a copyright and the second is showing an email link for webmaster. To me these are totally separate things with no connection between them.
Niether of your examples will work for automating the copyright year. Your second example is fine as far as the email link part, except I would note that you are inviting spam displaying this email link. You could just link to a page with a contact form on it instead.
This morning I implemented in 5 minutes a control to do what you want to do with the copyright, however it won't be available until the next release of mojoportal so adding this to your layout.master right now would only cause an error, it would not work. After you upgrade to the next release of mojoportal, you will be able to add a copyright label to your layout.master like this:
<portal:CopyrightLabel id="cl1" runat="server" BeginYear="2006" CopyrightBy="Source Tree Solutions, LLC" />
and it will do the magic of incrementing the year automatically for the current year.
