It seems that your sys admin has initiated a policy to block all links due to spam emails, which is a very good policy.  A lot of people click on those links without truly knowing what they are doing and wind up introducing a lot of problems for those that have to clean it up.  With the customer, they only see a shortcut blocked.  Try thinking of it from our point of view this time and you will see he logic behind it.  If you really want it that bad, you can cut and paste the link into your browser or just forward the email home.
