External Connection / Mail Server

Dear colleagues,

I have an internal e-mail server and in the last few days, I have received several login attempts in an attempt to send emails through IPS port 25 coming from other countries where we do not have employees. I would like to know how I could block connections from other countries only for login attempts/sending messages through our internal server.

  • You could try using a country block filter at the top of your firewall rule list or just s port 25 block rule from those countries.
