mail spam

Hi all,
I am using mikrotik as firewall and router which is directly connected to ISP and a AAA server(Linix base) running PPPoe which connect to mikrotik using a Public IP.Everything is working fine but I am getting mail spaming problem over AAA server which is being routed by MT-2.9.38.
How can i stop mail spaming ?


Thanks in advance

RouterOS is no capable of spam filtering as it has nothing to do with routing or low level networking (OSI level 2 and 3)
