Email DNS Records Guide

Adding email-related DNS records correctly ensures proper delivery and security of your emails. Here's how to configure the essential records:

MX Records Setup

MX records direct email traffic to the correct mail servers. Add them using either:

Preset Records (Recommended):

• Available for: Google Workspace, Microsoft 365, Fastmail, Proton Mail, Neo, Titan, iCloud, Zoho Mail
• Select your provider from the presets menu for automatic configuration

Custom Records:

1. Choose "MX" as record type
2. Enter "@" in Host field (or subdomain if applicable)
3. Set Priority (0-255) as specified by provider
4. Input mail server URL in Data field

DKIM and SPF Records

These TXT records authenticate your emails and prevent spoofing:

1. Select TXT/CNAME as record type
2. Enter provider's host information (or "@" if none specified)
3. Paste the DKIM/SPF record value
4. For multiple SPF records, add individually (system merges automatically)

DMARC Record Configuration

Add DMARC record as follows:

1. Select TXT as record type
2. Enter "_dmarc" in Host field
3. Input provider's DMARC record value
4. For multiple services, merge records using commas between email addresses

SRV Record Setup

1. Gather required information:

   • Service name (e.g., _smtp)
   • Protocol (e.g., _tcp)
   • Priority/TTL (optional)
   • Weight (single digit)
   • Port number
   • Target URL

2. Add record:

   • Type: SRV
   • Host: service.protocol
   • Priority: TTL number (if provided)
   • Data: weight port target.url

Remember to verify all records after adding them and allow time for propagation.
