Well, one really doesn't have anything to do with the other, and in many cases would be different addresses. My old pop3 server was "pop3.bellsouth.net", and my smtp was "smtp.bellsouth.net". If the pop3 worked, then changing the smtp wouldn't have any effect on the pop3 settings. It sounds like you are changing both settings.

As for the link...where are you trying to add it?

If you want to add it to a template, the simpliest thing to do is figure out where in the auction you want it to appear, and add a "other hyperlink" component - just fill in the blanks and you got your link!

Hope that helps!
