Email errors can be frustrating, but most have simple fixes with basic troubleshooting steps for email.
This guide walks you through the essential checks that our Support Team uses when assisting you, so you can resolve issues quickly yourself, too!

Basic Checks
- Confirm that your domain is active via ZACR WHOIS.
- Check the nameservers to see if they point to 1-grid.
- Verify DNS: MX, SPF, DKIM, DMARC records.
- Check SpamTitan to verify the status of inbound email delivery.
- Establish the status of emails on the firewall.
- Check MailChannels to confirm the status of outbound email delivery.
- Establish any errors flagged by them.
- Check our Network Status Page, as it might be that there is host maintenance or issues on the server.
- Check your internet connection as your firewall, antivirus or network settings may be blocking your email client.
- Temporarily disable your firewall and antivirus and try again.
- If you are on a School or Work network, certain ports might be blocked. Try to connect when you are on a different network, for example, your mobile provider.
Logging in to Webmail
- From any internet browser, you can log in to your email account directly via Webmail on our servers.
- Simply go to http://yourdomain.co.za/webmail or http://webmail.yourdomain.co.za.
- Log in using your email address, e.g name@yourdomain.co.za and the password that you set when you created the email account.
- If you are unable to log in, try logging in to your Control Panel and check or change the following:
- Make sure the account is created and is active.
- Change the password for the account, wait 5 minutes and try again.
Checking Email Routing
- Set routing to Local if your domain’s email is hosted at 1-grid.
- Set routing to Remote if you use Google Workspace, Microsoft 365, or another provider.
Troubleshooting Incoming Mail
- Verify that the MX records point correctly.
- Check SpamTitan logs and global email filters.
- Use Track Delivery in cPanel to trace failed messages and get email headers.
Troubleshooting Outgoing Mail
- Check the MailChannels status to identify if your emails are being blocked.
- Ensure that the correct SPF/DKIM/DMARC are published and valid.
- Avoid sending to invalid addresses or spamming multiple recipients at once.
Checking Mail Client Settings
- Check that you have used the correct server, ports and settings.
- Enable authentication for the outgoing server, and use SSL/TLS for secure communication.
| SSL Settings | Non-SSL Settings |
| Username: your complete email address | Username: your complete email address |
| Password: email account’s password | Password: email account’s password |
| Incoming Server: mail.yourdomain.com | Incoming Server: mail.yourdomain.com |
| IMAP Port: 993 POP3 Port: 995 | IMAP Port: 143 POP3 Port: 110 |
| Outgoing Server: mail.yourdomain.com | Outgoing Server: mail.yourdomain.com |
| SMTP Port: 465 | SMTP Port: 587 |
| SMTP requires authentication | SMTP requires authentication |
REMEMBER: Replace “yourdomain.com” with your actual domain name.

FAQs
How do I know if I should set routing to Local or Remote?
Set your routing to Local for 1-grid email hosting, and to Remote for external hosts (Google/Microsoft).
Why are my emails delayed?
Delays may occur due to MailChannels throttling or server congestion, so it is important to check Track Delivery first.
My mail client setup is failing. What’s wrong?
Confirm correct ports, authentication enabled, and SSL/TLS selected.
What should I do if my IP is blacklisted?
Contact Support with your public IP so we can see if we can assist in delisting.
Can I resolve MailChannels blocks myself?
In many cases, yes. Clean lists, avoid invalid addresses, and send responsibly. If blocks persist, escalate to Support.
