Robert Haskins, ZipLink
ZipLink is currently working on a technical solution to the problem of
outbound spam. We are a wholesale dialup ISP, and as such, can be a
source of spam. Our idea is to track, utilizing RADIUS accounting
records fed into an Oracle database, the IP addresses and usernames of
all customers logging into our dial up ports. Then, when a customer
attempts to send email, their outbound mail connection is redirected to
a mail relay which checks their current number of outbound messages
against preset limits in the database. If they exceed any of the limits,
the message is bounced/dropped. If they do not exceed the limit,
the message is allowed to go through and their email counts in the
database are updated to reflect their most recent activity.
We have successfully prototyped this functionality in a lab environment,
and are just now beginning limited POP testing before a full scale rollout
to follow later this year.
