Resolve Spam Problem
INo, I still consider the spam problem as one of the major pests of the Internet (more like a rash, maybe not bubonic plague), due to two reasons.
- Even in the major email services some spams get through, just the success rate got smaller in recent times.
- Spam consumes considerable resources for email service providers (MX machines as well as user database resources, if the spams get through also storage space), anti-spam solutions cost quite a bit for professional services and service outages due to spam attacks are still happening occasionally.
Most definitely not - The latest quarterly threat report from Proofpoint shows malicious message volume is up 85% from Q2, while the use of malicious URLs in spam email is up 2,200% from last year. If anything, the spam problem is getting worse. That said, spam filtering solutions are getting better.
Email authentication such as DMARC helps businesses to determine whether emails have been sent from trusted sources, and there are some highly effective advanced spam filters available that are much better at detecting and blocking spam email than they used to be. Provided businesses use a spam filtering service, it is possible to block the majority of malicious and nuisance messages and keep inboxes spam free.
Google’s filter for gmail is also a lot better than it was, and fewer spam messages are getting through. Unfortunately, as spam filtering solutions get better, cybercriminals find new ways to bypass defenses. The spam problem is never likely to totally solved.
