All outgoing links have our site address????

After linking to another site within a post it appears just fine on my page and looks correct in the html editor of the post, but if you click on the link after publishing it does not take you directly to the website URL. Instead, it redirects you through a link from our site. For example, in the post below:

https://www.metszilla.com/2012/01/30/mets-are-still-looking-for-a-lh-outfielder-ankiel-anyone/

When you click on the link to Rick Ankiel, the following URL comes up as you’re redirected:

https://www.metszilla.com/?SKuUIYSt

I want the URL for the actual site to come up, not our redirection script.

How can I change this? Thanks in advance for the help,
