Frequently Asked Questions

Find answers to common questions about email verification.

What is an MTA in email delivery?

An MTA (Mail Transfer Agent) is the software responsible for sending and receiving emails between mail servers. It routes messages from the sender’s server to the recipient’s inbox.

What does an MX record do?

An MX (Mail Exchange) record tells the internet which mail server is responsible for receiving emails for your domain. Without it, incoming emails can’t find their destination.

How are DNS records related to email delivery?

DNS records act like an address book for your domain. They direct where emails, websites, and other services should go. Properly configured DNS records ensure that your emails are delivered safely and recognized as legitimate.

What happens if my MX or DNS records are misconfigured?

If your MX or DNS records aren’t set up correctly, your emails may bounce, be marked as spam, or fail to reach recipients altogether.

How can VitaMail help me monitor and fix email delivery issues?

VitaMail includes DMARC monitoring that tracks authentication results, detects spoofing attempts, and alerts you to delivery or security problems. It helps you maintain trust, improve deliverability, and keep your domain protected.
