How To Hack The Internet Through Software R Mail?

Dude, hacking is illegal, so it's safe to say no one here is going to be an accessory by giving you detailed instructions on how to hack into someone else's stuff.  In the USA:

Hacking is covered under law Title 18: Crimes and Criminal Procedure: Part 1: Crimes: Chapter 47: Fraud and False Statements: Section 1030: Fraud and related activity in connection with computers.

The federal punishment for hacking into computers ranges from a fine or imprisonment for no more than one year to a fine and imprisonment for no more than twenty years. This wide range of punishment depends upon the seriousness of the criminal activity and what damage the hacker has done.

I would suggest you try googling the topic and doing your own research if you're interested in being a criminal and/or going to prison, rather than asking others to be an accessory to your criminal acts/hobby.
