Hi Experts,

Recently I got a security alert for open SMTP relay on port 25000 in our server.I checked for it and got the result as given below.

netstat -Aan|grep 25000

f1000e00337b3bb8 tcp4       0      0  *.25000               *.*                   LISTEN

Can you please let me know how to stop the incoming mail service on this port.

Thanks

Hi All,

For your information.I resolved this issue by changing the port no of SMTP to "0".This will allow out going mail but will restrict the incoming mails.

Thanks
