How to Authenticate Your Email in 2 Simple Steps

1. How to Authenticate Your Email in 2 Simple Steps Domain Authentication declares to the email providers that your email service provider is authorized to send emails in your stead. It will augment your reputation as a sender and will improve your email deliveribility. Explicitly stating that it comes from you, increases your standing with email service providers and makes it much less likely that they will classify your mail as junk. This, in turn, increases the likelihood of your mail reaching their inbox. You are also explicitly showing your recipients that this email does indeed comes from you, so they are less likely to mistake it as spam. This has become rather important, given the fact we are constantly bombarded with tons of spam masquerading as the real thing. Another phenomenon that has become alarmingly common these days is Phishing attacks. Phishing is a form of cyber warfare where a scammer pretends to be a reputed sender and tries to deceive people into clicking a bunch of malicious links which might expose their system to trojans and viruses. This could lead to valuable PAN information and passwords being siphoned off by unscrupulous individuals. You can resolve this issue if you authenticate email domain. Domain authentication is the very first step that you should take to prevent your

Fortunately, this is less complicated than it sounds and in the article below we will show how to authenticate email domain in just 2 steps. 1) Publishing an SPF record. SPF is a DNS TXT record that specifies all the email servers that are allowed to send mails on behalf of your domain. This prevents spammers from masquerading as you and sending messages on your behalf. You can easily verify if the SPF records for your domain are set up correctly by doing a SPF Record Check. 2) Signing all your outbound emails with DKIM keys. DKIM adds an encrypted signature to the header to all the emails. Email servers that receive the signed messages, use DKIM to decrypt the message header and verify the email wasn't altered after it was transmitted. SPF and DKIM have become virtually indispensable protocols that are used by ISPS to verify the identityof your emails, more so thanks to the ubiquity of DMARC as a validation tool. If you are using SpiceSendas your email service tool, then DomainAuthentication is a fairly straightforward process and can be achieved by publishing 3 DNS records. How Often You Should Change DKIM Keys? After your domain authentication, you may be wondering about how often you should change your DKIM keys. While there's no rule or time limit to change DKIM keys, it is best to rotate your keys. This would allow you to maintain the efficiency of DKIM authentication. In that respect, you can change your DKIM domain authentication keys once in every year.

3. It is necessary to understand that when you are changing your DKIM domain authentication key, your messages (in transit) may fail to authenticate. This is the case when the DNS record contains public key changes. The solution to this problem is to utilize more than one selector and change only one selector at one time. This would allow you to change keys without losing messages in transit. For instance, if you have a message and two DKIM keys, then you can sign the messages with both the keys. Even when one of the key changes, others would verify your messages and authenticate it. This would ensure DKIM domain authentication when you change your keys.
