Study Finds Service Providers Struggling to Deal with Spam Sent from Their Own Networks
- 4 percent said it is costing them more than $250,000 per year. Costs due to outbound spam include such things as IT helpdesk and anti-abuse team time.
- Almost 40 percent of respondents have had their IP addresses listed on Real Time Blackhole Lists (RBLs) in the past 12 months alone. RBLs are published lists of the addresses of computers or networks known to be sending out spam.
- A service provider may be "blacklisted" as a result of outbound spam, and thus have its customers' legitimate email blocked by other service providers.
- Nearly 70 percent of service providers are in the process of evaluating solutions for their outbound spam problem. 50 percent expect to deploy a solution within the next 12 months.
