hate getting the DSN from systems that don't realize that Spammers also
almost always use some innocent persons email and they get the notification
as Spam.
People that send notifications (Virus, Spam, etc...) are Spammers too.
DSNs for forged email are easy to ignore. Notifications that are
*not* DSNs are spam. It is easy to stop the backscatter (from me
and other SPF checkers) altogether by publishing an SPF record that FAILs for
IPs you don't want backscatter from.
