The downside: some valid mail may never make it to
your inbox.
You can also employ a more aggressive interactive spam filter, such as
Cloudmark Desktop (http://www.cloudmark.com/), which won??™t allow any
email to reach your inbox unless the sender is on an approved-senders list.
(Many ISPs and some web-based email providers offer this type of service to
their customers as well.) If a non-approved sender tries to send you a message,
the program sends back an email requesting that the sender fill out a
web form. This not only trips up spam (which is sent by machines), it lets
you reject humans with whom you??™d rather not correspond. Of course, you
can also easily add any sender to your approved list, but that in itself introduces
extra work. This approach can turn a flood of spam into a trickle, but
it won??™t ever let valid automated messages through, such as newsletters, registration
codes you paid for, or order confirmation emails from online merchants.
And spoofed messages, wherein the sender is made to look like
someone likely to be on your approved list (such as other people in your
domain), won??™t be stopped by these types of filters.
If you??™re running an online business, think twice before you
deploy one of these aggressive spam filters. The last thing
you want is a spam filter deleting your customers??™ emails!
And eBay users take note: spam filters are the number-one
cause of negative feedback for both buyers and sellers.
