Internet biggies and banks across the world have all geared up to fight spam on a large scale. Yes, some firms like Facebook, Google and Microsoft have joined hands with financial institutions such as Fidelity Investments, Pay Pal and created a set of protocols and industry standards which prevents spammers from sending spam e-mails and messages.
This novel approach helps in reducing online crimes and frauds such as credit card account information, credit card password stealing, personal information stealing etc.
This approach involves the use of two modern technologies namely the Sender policy Framework( SPF) and the DomainKeys Identifies Mail( DKIM) to fight spam. According to this, every e-mail that claims to have come from a corporate sector must be SPF or DKIM authenticated, if not the e-mail is not delivered to the target recepient/recepients.
