Blacklist of ip address


  • I am the system administrator for the mail server mentioned below. I think someone spoofed or apammed us and got us on the microsoft blacklist. I need to get us off. Nothing from any of our domains can get to any .msn or .hotmail address. This is a case of a good intention being poorly executed.  Any help would be appreciated.
