Introduction to SMTP Relay

Introduction to SMTP Relay

What is Simple Mail Transfer Protocol (SMTP)?

SMTP is a protocol used on the Internet for sending emails. It defines a set of rules for how messages should be transmitted between mail servers, and between mail clients (the software you use to manage your email, like Outlook or Apple Mail) and mail servers.

SMTP is used exclusively for sending emails, while other protocols like POP3 (Post Office Protocol 3) or IMAP (Internet Message Access Protocol) are used to retrieve or manage messages stored on a mail server.

Key Functions:

  • Protocol for Email Transmission: Allows for the sending of emails between servers.
  • Directs Email Flow: Manages the path an email takes from sender to recipient.


  • As of 2023, over 306 billion emails are sent and received each day, highlighting the critical role of SMTP in daily communications.
  • It serves as the backbone for email delivery, supporting both personal and professional communication globally.

What is SMTP Relay?

SMTP relay refers to the process of transferring an email from one mail server to another through the Internet. When you send an email, your email client uses SMTP to hand off the message to your email provider's SMTP server.

From there, the message is relayed to the recipient's SMTP server. Finally, the recipient's mail server will deliver the email to the recipient's mail client using POP3 or IMAP.

Why It's Important:

  • Spam Prevention: By using SMTP relay, service providers can better manage and filter spam, reducing unwanted emails.
  • Improved Deliverability: It helps in bypassing strict IP-based filtering, ensuring that legitimate emails reach their destination.
  • Scalability: Essential for businesses and organizations to send bulk emails, such as newsletters and transactional emails. Research shows that a well-configured SMTP relay can improve email deliverability rates by up to 99.9%.

What is Open Reay?

An open relay is a mail server configured in such a way that it allows anyone on the internet to send email through it, not just mail destined to or originating from known users.

This configuration is generally considered a security risk because it can be exploited by spammers and malicious actors to send unsolicited bulk email, or spam, without being easily traced back.

The reasons why open relays are considered harmful include:

  1. Spam Distribution: Open relays can be exploited by spammers to send large volumes of unsolicited emails, contributing to the global spam problem.
  2. Blacklisting: IP addresses of open relays can be blacklisted by other mail servers and anti-spam organizations, which can prevent legitimate emails from being delivered.
  3. Security Risks: By allowing unauthenticated email transmission, open relays may also be exploited for phishing attacks, spreading malware, or other malicious activities.
  4. Resource Abuse: Unauthorized use of an open relay can consume significant network and server resources, affecting the performance and reliability of legitimate services hosted on the same server.

How Does SMTP Relay Work?

How Does SMTP Relay Work?

SMTP relay, an important component of the email sending process, ensures that your email finds its way to the recipient's inbox, regardless of the domain.

It functions as an intermediary, facilitating email transfer from one server to another across the internet. This process is pivotal for businesses and individuals alike, ensuring efficient and reliable communication.

How SMTP Relay Operates

Initial Email Submission:

  • The process begins when an email is sent from an email client, such as Microsoft Outlook or Gmail.
  • The email client uses SMTP to submit the email to a server designated for outgoing mail, known as an SMTP server or email server.

Relay to Destination:

  • The SMTP server then forwards the email to the recipient’s SMTP server, acting as the "relay" in this process.
  • This step might involve multiple SMTP servers (or smtp relay servers) to navigate the complex architecture of the internet.

Delivery to Mailbox:

  • Once the email reaches the recipient’s SMTP server, it is transferred to the mail server responsible for holding the recipient's emails.
  • The email is finally delivered to the recipient’s mailbox, where it can be accessed through their email client.

Key Points in SMTP Relay Operation

Domain Name System (DNS) Lookup:

  • The SMTP server uses DNS to find the recipient’s domain’s mail exchange (MX) records, determining the destination SMTP server.
  • This DNS lookup is crucial for directing the email to the correct server for the recipient’s domain.

SMTP Authentication:

  • SMTP servers often require authentication (SMTP auth) to prevent abuse by spammers.
  • This involves credentials (username and password) or IP address recognition, ensuring that only authorized users can send emails.

Encryption for Security:

  • TLS (Transport Layer Security) encryption is frequently used during SMTP relay to protect the email content as it travels across the internet.
  • Encrypted transmission is vital for maintaining confidentiality and integrity, especially for sensitive communications.

Why SMTP Relay is Indispensable
