NIS 2014 21.3.0.12 Problem with Anti Spam

For the last two days I have run into the receiving of emails to be very slow, tried everything and then visted board and it shows that in 2012 a proble with antispam, I turned it of and imm speed returned, I tested as normal sending myself an email. I found this on both computers.

 

WIN 7 Pro

HP desktop 64bit windows live mail latest version

Toshiba 32bit  Windows live Mail          "         "

 

Can I turn of antispam or should I reinstall NIS checked no virus or problems on machines

 

Hope someone can point me in the right direction
