Default attack my mail server (help)

hello forum, for one day is having problems send mail local or external , I make netstat and I see many addresses connected ip to the port 25 of my server trying to send mail to users' account that neither they exist in my domain ,

the account of mail of the postmaster captures all the messages with spam and virus, and I have received as 6000 false mail, that I can make to stop this attack?

in these moments I have closed the port 25 with my firerwall , closing the port, I can send local and external mail, but I cannot receive, because they throw away me the server


comand netstat
