Knowledge Base: Recommended Domain Nameserver Configuration for Optimal Email Service with iCoreHosting
If you are utilizing iCoreHosting’s email services while hosting your website with a different provider, we strongly recommend pointing your domain’s nameservers to iCoreHosting’s nameservers. This ensures optimal functionality and simplifies DNS management for email services.
Recommended Nameservers
For cPanel Hosting Services:
• nscp1.icorehosting.com
• nscp2.icorehosting.com
For DirectAdmin Hosting Services:
• nsda1.icorehosting.com
• nsda2.icorehosting.com
Why Point to iCoreHosting Nameservers?
Managing DNS records can be complex, particularly for email services that require multiple configurations. Pointing your domain to iCoreHosting’s nameservers provides the following advantages:
1.Comprehensive DNS Configuration for Email Services
Email functionality relies on several DNS records, such as:
•MX Records: To route incoming emails to the correct mail servers.
•SPF Records: To verify the sender’s authenticity and reduce spam.
•DKIM Records: To authenticate outgoing emails and ensure integrity.
•DMARC Records: To enhance email security and monitor policies.
•A Records: For services like webmail, mail, pop, smtp, and imap.
These records are automatically configured when using iCoreHosting’s nameservers, ensuring smooth and reliable email delivery.
2.Simplified DNS Management for Web Services
Websites hosted externally typically require only a single A Record to point to the external web server. Keeping your domain’s nameservers with iCoreHosting centralizes the management of all required DNS records while allowing seamless connectivity to your external web hosting.
3.Reduced Risk of Configuration Errors
By utilizing iCoreHosting’s nameservers, you minimize the chance of misconfigurations that could disrupt email services or impact email deliverability.
How to Update Your Domain’s Nameservers
1.Log in to your domain registrar’s control panel.
2.Locate the nameserver settings for your domain.
3.Update the nameservers to:
• For cPanel Services: nscp1.icorehosting.com and nscp2.icorehosting.com
• For DirectAdmin Services: nsda1.icorehosting.com and nsda2.icorehosting.com
4.Save your changes and allow up to 24–48 hours for DNS propagation.
By following this best practice, you ensure reliable and professional-grade email performance while maintaining seamless website functionality. For assistance, please contact iCoreHosting Support at any time.
