As a general rule, the vast majority of spam sourced from the zombies
does *not* have the From of the computer which sourced the spam.

You do not determine the source of a spam from the From. You determine
the source of a spam by carefully examining the headers to determine the
source IP.

The small minority of spam which comes from a mail account in which the
From actually *does* represent th source of the spam comes from cracked
webmail passwords, so the source of the spam in those cases is the
From's webmail account.

In such a case the machine in question is not the source of the webmail.

As a general rule, except for the cracked webmail account example above,
the source of a spam is *not* the From.
