| How ISPs can eliminate spam, lift profitability and improve ...
Australias Internet service providers could save their customers significant time, money and frustration in dealing with the common menace of unwanted email - if only they could eliminate spam. The good news is that they can achieve this apparent miracle. By switching from the filter-based anti-spam solutions that most use, to challenge-response technology, ISPs can reduce the torrent of spam deluging their clients to a mere trickle. The benefits for those ISPs that make the switch can be far-reaching: higher profitability, possible staff reductions, plus improved customer service which can deliver a significant competitive edge. My own experience suggests that challenge-response is a far more effective than filtering at curbing spam. Email is the life blood of PR communications, and our circulation was growing more sluggish by the day.

Email server administrators commonly configure their servers to reject messages from IP addresses listed on one or more blacklist to help minimize spam.
Study: Image spam levels rocket
Image spam levels have soared over the past six months, now accounting for over half of all spam, according to new research. Figures released by Marshal show that image spam has jumped by 175 percent since September last year, representing 56 percent of all spam sent over the past six months.This rise in picture-based spam coincides with the decline of messages containing embedded URL links, the study claims. In 2004, 96 percent of spam messages included a website hyperlink for the recipient to click. This figure has dropped to just over half, according to the research.Spammers are constantly morphing their practices to overcome anti-spam filters, said Bradley Anstis, director of product management for Marshal. And we can expect image spam levels to continue to increase this year.
