- If X is a spammer she will eventually run out of money and will have to
pay her provider again (for sending mails).(Assuming we use some sort of
SMTP extension or some other mechanism for authenticating X's account)
- If Y replies to X's mail the same transaction happens the other way round.
So, if I am a normal user I am not likely to run out of money in my
account because i'll be sending as well as receiving mails. If there is
some deduction in my account but i know i didn't send any mails then it's
most likely that my machine is infected(assuming there is no way to
prevent zombies from sending authenticated mail ).
And I would love to be spammed because that will only increase the amount
of money in my account.
And so what happens for 'free' community mailing lists and other such affinity
groups, which get one mail from a group member and send it out to the other
thousand members of the affinity group?
Not all E-mail send/receive traffic is anything remotely like symmetrical.
