I am a newbie. There are several things I don't understand. Please explain them to me.
I read through http://forum.spamcop.net/forums/index.php?...findpost&p=1018 .
It is my understanding (possibly misunderstanding) that spammers test for valid e-mail addresses by randomly putting together combinations of letters to form an e-mail address, sending a forged e-mail to that randomly put together e-mail address, and adding e-mail addresses to their list which they do not receive bounce messages about in the mailbox for the forged address. I thought that bouncing messages would trick spammers into thinking an address is invalid. Please correct me if I am wrong.
Therefore, if the spammer sets up an account at the forged address, wouldn't the chance that an innocent victim would receive a bounce message be very small? Or am I wrong?
Why would an ISP have repercussions for users who send out bounce messages which are "effectively forged" to fight spam because aren't ISPs interested in fighting spam as well?
I don't understand why e-mails saying a virus you sent was intercepted are a bad thing. It is my understanding (possibly false understanding) that those messages help people unknowing infected with a virus by notifying them that they have a virus. It is also my understanding (possibly false understanding) that those e-mails help people whose e-mail addresses are forged by viruses by notifying them that their e-mail address has been forged by a virus. Please correct me if I am wrong. Thank you.
