How Email Works

Messages are exchanged between servers using the SMTP protocol with various MTAs (Mail Transfer Agents) such as Sendmail, Postfix, qmail, or Exim. Messages can be stored on the server for the user to access, they can be downloaded and stored in the email client for offline use, or stored both places.

Understanding Email Errors

Sending an email should be a straightforward process, but sometimes, you may encounter errors that hinder the delivery of your messages. Here, we will explore the most common email sending errors and how to troubleshoot them effectively.

SMTP Authentication Error (Error 535)

SMTP (Simple Mail Transfer Protocol) authentication is the process of verifying the sender’s identity before allowing access to the mail server. Error 535 occurs when there is an authentication failure during the email transmission process.

Causes:

• Incorrect login credentials, such as an invalid username or password
• Issues with the mail server settings
• Firewall or antivirus software blocking the connection
• IP address blacklistin

Solutions:

Double-check your login credentials to ensure they are accurate and up-to-date.

Verify that your email client is configured with the correct server settings, including the SMTP server address, port number, and security options.

Temporarily disable your firewall or antivirus software and attempt to send the email again. If successful, reconfigure the settings to allow email communication.

Check if your IP address has been blacklisted by using online blacklist checking tools. If blacklisted, follow the steps provided by the respective blacklist to request removal.

SMTP Error: “550 5.7.1 Relaying Denied”

When you receive the error message “550 5.7.1 Relaying Denied,” it means that the mail server you’re using doesn’t allow relaying. Relaying refers to the act of sending an email through a server that is not directly connected to the destination domain.

To resolve this error, follow these steps:

Ensure you’re using the correct outgoing mail server settings provided by your email service provider.

Double-check the recipient’s email address for any typos or errors.

If you’re using a third-party email client, verify that you’ve correctly configured the SMTP server settings.

Authentication Failure: “SMTP Authentication Required”

When you encounter the error message “SMTP Authentication Required,” it means that your email client or service hasn’t been configured to authenticate before sending emails.

To resolve this error, follow these steps:

• Check your email client settings and ensure that the SMTP authentication option is enabled.
• Verify that the username and password you’re using to log in to your email account are correct. If you recently changed your email account password, update it in your email client settings to match the new password.

Connection Timeout: “SMTP Connection Timed Out”

The “SMTP Connection Timed Out” error occurs when your email client or server fails to establish a connection with the recipient’s mail server within the specified time limit. To troubleshoot this error, consider the following steps:

• Ensure you have a stable internet connection. Unstable connections can lead to timeouts.
• Disable any firewall or antivirus software that might be blocking the email client’s connection.
• Contact your email service provider or IT department to check if there are any server-side issues causing the timeout.

DNS Resolution Error (Error 550)

A DNS (Domain Name System) resolution error occurs when the mail server is unable to resolve the recipient’s email address.

Causes:

Misspelled or invalid recipient email address

DNS configuration issues

Mail server restrictions or blacklisting

Solutions:

Ensure that the recipient’s email address is accurate and properly formatted.

Contact the recipient to confirm the validity of their email address.

Verify your DNS settings to ensure they are configured correctly.

Check if your IP address or domain has been blacklisted. If so, take steps to address the issue and request removal.
