I'll setup and configure SpamAssasin into postfix smtp server or any-other linux server. SpamAsasin will filter spam with prescribed spam score (0-9).
if you are getting lots of spam messaging into your private domain smtp account then you need to have SpamAssasin must.
SpamAssassin is an anti-spam tool which helps filter out unwanted messages.
SpamAssassin screens each incoming message and scores it based on its spam characteristics. By default, SpamAssassin considers messages with a score of 5 to be spam; however, i can adjust the spam score limit according to your preference.
