Email users have raised concerns about services that fail to ensure spam is not sent from the provider's network, otherwise known as outbound spam.
Eight in 10 email users responding to an Osterman Research poll, commissioned by Commtouch, said they believe it is important or extremely important that their service provider ensured that outbound spam was not sent out.
More than three-quarters of service providers polled placed importance on identifying spam senders within their networks, while 75 per cent said implementing an outbound spam solution would help them improve customer service.
"Many providers that have tried to prevent outbound spam using various techniques are still suffering from false positives and poor detection levels," said Asaf Greiner, Commtouch's vice president of products.
"The only way to effectively keep off of blacklists is to block outgoing spam while simultaneously targeting the sources of the problem the spammer accounts, compromised accounts and zombies," Greiner added.
Michael Osterman, president and founder of Osterman Research, added that eliminating outbound spam can help providers cut costs and improve the level of service they give to customers.
A recent report from Symantec revealed that one in every 1.11 emails sent in May was spam from new and previously unknown sources. The research also discovered that nine in 10 spam emails now contains a URL link, just five per cent of which lead to genuine websites.
