Blocking spam emails.

I am successfully blocking some spam emails by putting them in the spam guard on my lsp but one is constantly getting through. Can someone explain why this is the exception. It takes the form of http://go.ab.by/11a11. I've change the middle letters between the dots so nobody actually tries to click on this but you know what I'm meaning or those who are likely to be able to provide answers for me will understand what I mean. The number after the slash is never the same. I thought that the what was after the slash didn't matter. I'm sick of getting these f. spams, usually 4 - 6 daily.
