What is DKIM?

September 21, 2017, Written by 0 comment

Known as DomainKeys Identified Mail is for identification on email designed to prevent email spoofing. It allows the email server to check that the incoming email claimed to have come from a specific domain was authorized by the owner of that sending domain. It is intended to prevent forged sender addresses in emails, a technique often used in phishing and email spam.

In technical terms, DKIM lets a domain name associate its name with an email message by affixing a digital signature to it. Verification is carried out using the signer’s public key published in the DNS. A valid signature guarantees that some parts of the email (possibly including attachments) have not been modified since the signature was affixed. Usually, DKIM signatures are not visible to end-users, and are affixed or verified by the infrastructure rather than message’s authors and recipients. In that respect, DKIM differs from end-to-end digital signatures. Our virtuemail has the option for DKIM.  You can contact us o understand more.
