How does one go about separating the Domain Name from the Fully Qualified
Domain Name. For example:
Connect from 207.217.120.150:48077
EHLO parakeet.mail.pas.earthlink.net
MAIL FROM:<spamblocker-challenge(_at_)bounce(_dot_)earthlink(_dot_)net>
SIZE=3269
RCPT TO:<prolatefseuy(_at_)mail(_dot_)yellowhead(_dot_)com>
This is a legitimate message (background bounce actually), but the HELO
Domain and the MAIL FROM: Domain will not pass an SPF test. However, the
actual Domain Name <earthlink.net> will.
