MTNL has blocked a part of its broadband network that allows sending of emails through private email servers after ISPs in Mumbai came under a heavy DDoS attack last week, crippling internet speeds in the city. MTNL will be blocking ‘Port 25’ used for sending emails on private servers, which will essentially stop spammers and hackers from sending out bulk emails in a network using private servers.
