Email and DNS Hosting – Important Security Configuration Options
Ensure optimal email security for your business with ItsBroken Digital’s email and DNS hosting assistance in creating and publishing essential email authentication records such as SPF, DKIM, PTR, and DMARC, which protect against spam and phishing attacks by verifying the legitimacy of emails sent from your domain.
SPF, DKIM, PTR, and DMARC are all email authentication methods that help protect against spam and phishing attacks by verifying the legitimacy of emails sent from your domain. SPF (Sender Policy Framework) records are used to indicate which mail servers are authorized to send emails from your domain. DKIM (DomainKeys Identified Mail) uses public-key cryptography to verify emails sent from a specific domain. PTR (Reverse Lookup) records provide information about the host name and IP address associated with your domain, which helps mail servers validate incoming mail from legitimate sources.
DMARC (Domain-based Message Authentication, Reporting and Conformance) uses SPF and DKIM to identify the legitimate source of an email message and reject any unauthorized messages sent in its name. It is important to note that no single method is foolproof and it is recommended to use a combination of these methods for maximum protection.
ItsBroken Digital security engineers can assist your business with creating and publishing records to achieve the best email security possible.
Sender Policy Framework (SPF) Records – Mail Reputation Security
SPF records are a critical element of Professional Email Configuration, as they help verify the legitimacy of emails sent from your domain. SPF records are TXT records that are added to your domain’s DNS zone file and indicate which mail servers you’ve authorized to send emails from your domain. When an email recipient’s server receives an email from one of your domains, it checks the SPF record in order to verify that the sender is indeed authorized by you. Accurately configuring your SPF records can reduce the amount of spam associated with emails sent from your domains and protect against malicious actors posing as someone else in messages.
We can construct and install your domain’s SPF record(s) so that the maximum security is achieved.

DomainKeys Identified Mail (DKIM) – Email Communication Security
DKIM (DomainKeys Identified Mail) is an important email authentication standard that uses public-key cryptography to verify emails sent from a specific domain. By configuring proper DKIM records, senders can ensure their emails are securely signed and can therefore reach the recipient’s inbox with higher deliverability. When setting up DKIM records, it is important to review all settings carefully and modify headers as necessary, such as Return-Path or From address. Additionally, you should create unique selectors for each domain, use appropriate DNS records types like TXT or CNAME, as well as align all changes with your SPF (Sender Policy Framework) policy. Taking these steps will help properly configure your DKIM record to maximize deliverability and protect against spoofing attacks.

Reverse Lookup (PTR) – Email Origination Security
Reverse Lookup records are a critical component of maintaining an efficient, secure and professional online presence. They help ensure that email sent from servers associated with your domain is correctly identified and has a better chance of being delivered to the correct inbox. Configuring Reverse Lookup records involves setting up specific information about the host name and IP address associated with your domain, which helps mail servers validate incoming mail from legitimate sources. Additionally, configuring your Reverse Lookup records can improve overall server performance by allowing users to access files faster since the host will only have to look up each domain once for all requests. Proper configuration of Reverse Lookup records may also be beneficial in protecting against malicious activity such as spam, phishing, or mail bombing.

Bounce Address Tag Validation (BATV) – Antispam Security
A BATV record, or Bounce Address Tag Validation, is a useful method to help detect and block spam messages. By configuring and enabling these records within an email server, the level of incoming malicious emails can be drastically reduced; this helps protect not only the email server itself but all accounts associated with the server. This can be done by setting up rules that tag outbound emails with unique identifiers based off of specific criteria which, in turn, enable identification tagging on subsequently returning emails. As a result, any spoofed messages imitating original outbound mail will not pass validation checks and therefore be blocked from ever reaching their destination. Overall, configuring and enabling BATV records is an essential step for businesses–both large and small–looking to safeguard their email infrastructure from malicious activity.

Domain-based Message Authentication, Reporting and Conformance (DMARC) – Email Communication Security
DMARC, which stands for ‘Domain-based Message Authentication, Reporting and Conformance’, is an email authentication protocol designed to protect senders and receivers from illegitimate emails. It works by using Sender Policy Framework (SPF) and DKIM (DomainKeys Identified Mail) to identify the legitimate source of an email message and reject any unauthorized messages sent in its name. We can configure DMARC records to ensure a fully secure mailbox environment; it prevents phishing attacks from spoofing legitimate accounts or scraping confidential information from sent messages. By validating that each message entering your mailboxes has been sent from a legitimate domain, we can guarantee superlative protection for our customers’ communication system.
