which software for professional Mailling?

[Matthias Mann]

HiYou!   I like to work with big archives of mailadresses and need a program that is able to send SPAM and organize to let it be, that people they don´t like my SPAMS will get never a Mail of me again. And i could need a tool that can scan the web for mailadresses. Is there somthing like that on the 4CD set of Debian 2.2r0 potato?   Thanx for every useful tip!
