Core Solutions is one of the first hosting providers in Estonia who is offering to its customers additional possibilities for improving the legitimacy and reliability of the emails that are sent through our servers.
The primary advantage of this system for e-mail recipients is it allows the signing domain to reliably identify a stream of legitimate email, thereby allowing domain-based blacklists and whitelists to be more effective. This is also likely to make some kinds of phishing attacks easier to detect.
