Cheat Sheet with all the details for WHMCS

Step 1: Add a new domain

  1. Place a new order from your WHMCS. You are required to enter your domain.
  2. After placing the order, you will be redirected to your Client Area. An alert will be shown until you verify the domain by adding a TXT record to your DNS (see next step).

Step 2: Add the Required DNS Records

This configuration must be done at the domain's registrar or DNS hosting provider (e.g., WHMCS, Cloudflare, Namecheap, GoDaddy):

✅ 1. TXT (Domain Verification)

Get the TXT verification details from WHMCS Client Area and add it to your DNS:

Type Name/Host Value TTL
TXT mx-verification Provided verification token 3600

Verifies your domain with us

This domain verification DNS record is required before you can create the email addresses or manage the product.
The other DNS records can be added / updated after the email migration.

✅ 2. MX (Mail Exchange)

Directs incoming email to us. You can wait to make this change after we complete the email migration.

Remove existing MX records first

Type Name / Host Value Priority TTL
MX @ or yourdomain.com mx.emailarray.com 5 3600
MX @ or yourdomain.com mx2.emailarray.com 10 3600

✅ 3. SPF (Sender Policy Framework)

Authorizes us to send emails on your domain's behalf and prevents bad actors from sending emails on your behalf. 

If there's an existing SPF record: Add include:emailarray.com before -all

Type Name Value TTL
TXT @ or yourdomain.com v=spf1 include:emailarray.com ~all 3600

✅ 4. Webmail Access (Optional but Recommended)

Type Name Value TTL
CNAME webmail webredirect.emailarray.com 3600

Lets users access Webmail via webmail.yourdomain.com

✅ 5. DKIM (DomainKeys Identified Mail)

How to Enable DKIM:

  1. Go to your WHMCS Client Area -> Click on the email hosting product -> Click on DKIM.
  2. Click on Enable.
  3. Add the generated Host and Key from WHMCS to your DNS as a TXT record:
Type Name (Host) Value (TXT) TTL
TXT Provided Host by WHMCS Provided Key by WHMCS 3600

Improves email deliverability by authenticating the sender.
DKIM helps protect against email spoofing and phishing attacks.

✅ 6. Autodiscover & Autoconfig (Optional but Recommended)

Type Name Value TTL
A autodiscover.yourdomain.com 69.28.212.195 3600
A autoconfig.yourdomain.com 69.28.212.195 3600

Don't forget to replace yourdomain.com with your own domain name

Enables automatic configuration for email clients, such as Outlook, Thunderbird, eM Client, etc.

Step 3: Create Email Account

  1. Go to your WHMCS Client Area -> Click on the email hosting product -> Click on Accounts.
  2. Click the Add Mailbox button.
  3. Fill in the new user’s details (username, password, quota, etc.).
  4. Click Save.

Step 4: Access Webmail

  • Option 1: webmail.yourdomain.com (if Webmail CNAME is configured in your DNS) and login with your full email address and password. You can bookmark the URL.
  • Option 2: 
    • Go to your WHMCS Client Area -> Click on the email hosting product -> Click on Accounts.
    • In the mailboxes list, click the Webmail button next to the desired account. This opens a new tab and logs you in automatically.
    • You can now bookmark the URL and use it to log in with your email address and password.
  • Option 3: Go to https://login.emailarray.com/ and login with your full email address and password.

  • CardDAV: https://yourdomain--com.w.emailarray.com/carddav

Troubleshooting

  • DNS changes can take up to 24 hours to propagate
  • No incoming emails: Check MX records using mxtoolbox.com
  • Emails going to Spam: Ensure SPF and DKIM records are properly configured with the domain's DNS provider (check with mxtoolbox.com). Add DMARC records to DNS provider.
