As part of our anti-spam efforts, NSA Internet Technologies Ltd. employes the DKIM Technology (DomainKeys) to sign outgoing mail, and verify signatures of incoming mail (and authenticate them with the original sending domain).
Implications: Our customers
When you send mail: We sign your outgoing mail, which increases the chance that the business partner receiving your email will actually receive your mail into his/her inbox.
When you receive mail: There is a very low chance that spammers will sign their outgoing mails. This means we can use DKIM as a decision factor of whether or not to accept the mail as legitimate (and allow it into your inbox).
Implications: Internet Sites Around the World
When you send a signed email to NSA: We authenticate you, and there is a higher chance that it will reach our customer’s mailboxes.
