Getting started

Welcome to Mailbig! This guide will walk you through everything you need to set up your email hosting and get your domain sending and receiving emails correctly. Follow each section in order for the best experience.

What You’ll Need Before You Start

• A registered domain name (e.g., yourdomain.com)

• Access to your domain’s DNS management panel (provided by your domain registrar, e.g., GoDaddy, Namecheap, Cloudflare, etc.)

• Access to your Mailbig.net Email control panel

DNS changes can take anywhere from a few minutes to 48 hours to propagate worldwide. This is normal; be patient after making changes.

Step 1: Access Your Email Control Panel

Your Mailbig.net Email control panel (EasyMailControl) is the central hub where you manage your domains, email accounts, DKIM keys, and all other settings.

Watch the video below for a walkthrough of the control panel:

From the dashboard you can manage domains, create email accounts, view usage, find DKIM keys.

Step 2: Add Your Domain

Before you can create email accounts or configure DNS records, you need to add your domain.

▶️ Watch the video below for a step-by-step walkthrough on adding your domain:

To add your domain:

1. Log in to your Mailbig.net Email control panel

2. Navigate to Domains → Add New Domain

3. Enter your domain name (e.g., yourdomain.com) and click Add Domain

Tip: If your registrar already has old MX records, delete them before adding the new one to avoid conflicts

Step 3: Point Your Domain to Mailbig.net (MX Records)

MX (Mail Exchanger) records tell the internet where to deliver emails for your domain. Without this, no one can send emails to you.

Log in to your domain registrar’s DNS panel and add the following MX record:

What this means:

• Host/Name @ means your root domain (yourdomain.com)

• Priority 10 is the preference value — lower numbers are tried first

• All incoming emails for your domain will be routed through m-mx.easymailcontrol.com

Tip: If your registrar already has old MX records, delete them before adding the new one to avoid conflicts.

Step 4: Set Up Your SPF Record

SPF (Sender Policy Framework) tells receiving mail servers which servers are authorized to send email on behalf of your domain. This prevents spammers from spoofing your domain and helps your emails land in the inbox instead of spam.

Add the following DNS TXT record to your domain:

Breaking this down:

• v=spf1 — Declares this is an SPF record

• include:spf.easymailcontrol.com — Authorizes Mailbig.net’s mail servers to send on your behalf

• a — Also authorizes the IP address of your domain’s A record

• mx — Also authorizes your domain’s MX servers to send mail

• -all — Hard fail: any server not listed above is NOT authorized. This is the strictest and most recommended setting.

Important: You can only have one SPF TXT record per domain. If you already have one, merge the values instead of adding a second record.

Step 5: Set Up Your DKIM Record

DKIM (DomainKeys Identified Mail) adds a digital signature to your outgoing emails, proving they genuinely came from your domain and haven’t been tampered with. It’s a key factor in email deliverability.

Your DKIM record is unique to your domain and must be obtained from Control Panel. It will be created automatically when you add a domain. Please keep in mind that each domain you add in the control panel will have its own DKIM key, and you must use the unique DKIM key assigned to each domain.

Watch the video below for a step-by-step walkthrough on finding your DKIM record:

General steps (shown in the video):

1. Navigate to Account Manager → Find DKIM Key

2. Copy the TXT record name (selector) and value provided

3. Add this as a TXT record in your domain’s DNS panel

Note: The DKIM record name will look something like default._domainkey.yourdomain.com and the value will be a long string starting with v=DKIM1;.

Step 6: Set Up Your DMARC Record

DMARC (Domain-based Message Authentication, Reporting & Conformance) ties SPF and DKIM together. It tells receiving mail servers what to do if an email fails SPF or DKIM checks, and optionally sends you reports about those failures.

Add the following TXT record to your DNS:

What this means:

• v=DMARC1 — Declares this is a DMARC record

• p=none — None enforcement (monitor mode). Emails that fail checks are still delivered, but you can monitor what’s happening. This is the recommended starting policy.

DMARC policy options explained:

Recommendation: Start with p=none as configured above. Once you’ve confirmed your SPF and DKIM are working correctly (usually after a week or two of monitoring), you can upgrade to p=quarantine or p=reject for stronger protection.

Step 7: Create Your Email Accounts

Once your DNS records are in place, you can create mailboxes for your domain.

1. Log in to your Mailbig.net** Email control panel**

2. Go to Email Accounts → Create New Account

3. Enter the username (e.g., hello, support, john)

4. Set a strong password

5. Choose your mailbox storage limit

6. Click Create

Your email address will be in the format: [email protected]

Step 8: Access Your Email

Webmail:

RoundCube: https://mercury.easymailcontrol.com/roundcube/ Supply username (e.g., [email protected]) and password and you'll log in.

Email Clients (Outlook, Thunderbird, Apple Mail, etc.): Use the following settings:

Incoming Mail (IMAP — Recommended):

• Server: m-imap.easymailcontrol.com

• Port: 993 (SSL) or 143 (STARTTLS)

Incoming mail (POP):

• Server: m-pop.easymailcontrol.com

• Port: 995 (SSL) or 110 (STARTTLS)

Outgoing Mail (SMTP):

• Server: m-smtp.easymailcontrol.com

• Port: 587 (STARTTLS)

• Authentication: Required (use your full email address and password)

Mobile Devices: Use the same IMAP/SMTP settings above. Most modern apps (Gmail app, Apple Mail, Outlook mobile) will auto-configure when you enter your email and password.

DNS Records Summary

Here’s a complete reference of all records you need to add:

Troubleshooting

Emails going to spam? Make sure all three records — SPF, DKIM, and DMARC — are correctly configured. Use our free tool, Email Record Scanner, and verify your records.

Not receiving emails? Double-check that your MX record is set m-mx.easymailcontrol.com with priority 10 and that old MX records have been removed.

DNS changes not working yet? DNS propagation can take up to 48 hours. Use whatsmydns.net to check propagation status across the globe.

DKIM verification failing? Make sure you copied the full DKIM value from your control panel without any line breaks or extra spaces.
