Email Not Sending or Receiving
Email Troubleshooting
If you're having trouble sending or receiving emails, follow these troubleshooting steps.
Not Receiving Emails
1. Check Spam/Junk Folder
Emails may be filtered to spam. Check your spam folder and mark legitimate emails as "Not Spam."
2. Verify MX Records
Your domain's MX records must point to our mail servers. In DirectAdmin:
- Go to DNS Management
- Verify MX records point to your server
3. Check Email Account Exists
Ensure the email account is created in DirectAdmin under E-Mail Accounts.
4. Check Disk Quota
If your email account is full, new emails will bounce. Check quota in DirectAdmin → E-Mail Accounts.
Not Sending Emails
1. Check Outgoing Server Settings
Ensure your email client uses:
- SMTP Server: mail.yourdomain.com
- Port: 587 (TLS) or 465 (SSL)
- Authentication: Required
- Username: Full email address
2. Check Sending Limits
Shared hosting has sending limits to prevent spam. If you're sending bulk emails, use a dedicated email service.
3. IP Reputation
If emails are being rejected, the receiving server may be blocking based on reputation. Check if your domain/IP is blacklisted at MXToolbox.
Authentication Issues
Set up SPF, DKIM, and DMARC records to improve deliverability. See our email authentication guides in the Email section of this knowledgebase.
