Understanding Spam and Email Spoofing


Spam emails are unsolicited messages sent in bulk, often for advertising, phishing, or spreading malware. Spam filters are designed to block these emails, but they can sometimes mistakenly mark legitimate emails as spam, especially if proper authentication measures are not in place.

Email Spoofing

Email spoofing involves forging the sender address on emails to make them appear as if they are from a trusted source. This technique is commonly used in phishing attacks to deceive recipients into revealing sensitive information or downloading malicious software.

Steps to Properly Set Up a Custom Sender Email

To avoid being marked as spam and prevent email spoofing, we need to follow these steps to configure your custom sender email properly:

1. Requirement for Verifying Your Domain

  • A Valid email inbox: The sender's email must be a valid email inbox, and you will need to receive a verification email. If you haven't got an inbox, you will need to create an inbox.

  • Domain Verification: Log in to your domain registrar's website (E.g., GoDaddy, Cloudflare, etc.) and add the DNS records provided by EventNook to verify your domain ownership.

2. Configure SPF (Sender Policy Framework)

  • Purpose: SPF specifies which mail servers are authorized to send emails on behalf of your domain.

  • Configuration: Add an SPF record to your domain's DNS settings. This record lists the IP addresses or hostnames of authorized mail servers.

  • Example SPF Record:

    v=spf1 -all

3. Set Up DKIM (DomainKeys Identified Mail)

  • Purpose: DKIM adds a digital signature to your emails, verifying the sender and ensuring the email has not been altered during transit.

  • Configuration: Generate a DKIM key pair (public and private keys). Publish the public key as a DNS TXT record.

    Example DKIM Record: IN TXT "v=DKIM1; k=rsa; p=public_key"

4. Implement DMARC (Domain-based Message Authentication, Reporting, and Conformance)

  • Purpose: DMARC builds on SPF and DKIM, allowing domain owners to specify how unauthenticated emails should be handled and providing a mechanism for reporting.

  • Configuration: Create a DMARC policy to define how receivers should treat emails that fail SPF or DKIM checks.

    Example DMARC Record: IN TXT "v=DMARC1; p=reject;"
