| Image spam becoming a growing challenge
There are hundreds of millions of spam email messages being sent every day. This has been a significant problem as spam covers 90% of all emails worldwide. Now this has become an even bigger challenge due to increased volume of image spam.
Image spam is a serious and growing problem, not least because of its ability to circumvent traditional email spam filters to clog servers and inboxes. In just half a year, the problem of image spam has become general enough to be representative of 35 per cent of all junk mail. Not only this, but image spam is taking up 70 per cent of the bandwidth bulge on account of the large file sizes every single one represents.
Apart from taking up valuable bandwidth, the time taken to filter out and destroy spam represents a significant burden on both IT staff and personnel in businesses and organizations.
Spam on IP telephony
Spam filters can easily be trained to give better than 90 per cent effectiveness with zero false positives, and for those who still suffer from a lot of spam in their inboxes, they are either not updating their spam databases often enough, or they just do not see the value of getting 90 per cent fewer email messages. There was also a bout of Spasms (spam over SMS) - less of a problem for businesses, where this does not seem to have been endemic, but pretty nasty for many children who find that they get messages asking for a response, and then find that up to £10 has been taken from their mobile account as a result. .
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.
