How to troubleshoot email that is not sending/receiving

Email issues can be frustrating, but most problems have straightforward solutions. This guide walks you through the most common reasons emails fail to send or receive and how to fix them in DirectAdmin.

Prerequisite: You need an active web hosting plan with DuelHost.

Step-by-step guide

Step 1: Log in to DirectAdmin

Step 2: Click “E-mail Manager” in the sidebar

Step 3: Click “E-mail Accounts”

Step 4: View email accounts and check quota/status

Step 5: Go to “Account Manager” in the sidebar

Tips and notes

• Check your spam/junk folder before assuming an email was not delivered
• Verify that your SPF, DKIM, and DMARC records are set up correctly
• Make sure your mailbox is not full, as that can prevent new messages from arriving
• If sending fails, check that your email client settings match the recommended SMTP configuration
