Quick Setup

Get your email hosting up and running in minutes. This guide walks you through adding a domain, configuring DNS, creating accounts, and connecting your email client.

Before you begin

You'll need access to your domain's DNS provider (where your domain is registered or where its DNS is hosted). Some basic DNS knowledge is helpful — if you're unsure, your registrar's support team can usually assist.

Setup Steps

  1. Log in to your Control Panel
    Sign in to the Control Panel at email.adastra.ad.
  2. Add your domain
    In the Control Panel, navigate to the Domains section and add your domain name. You may be asked to verify ownership by adding a DNS TXT record.
  3. Configure your DNS records
    Add the MX, SPF and DKIM records below at your DNS provider so mail routes to Overton.cloud and authenticates correctly.
  4. Create your email accounts
    Go to Email Accounts, click Create Account, and set a username, password, and optional quota.
  5. Connect your email client
    Use the server settings below to set up IMAP/POP and SMTP in your mail app.

DNS Configuration

Configure the following records through your DNS provider.

DNS propagation

DNS changes can take up to 24–48 hours to propagate globally, though they often take effect much sooner.

MX Records

Your MX records are specific to your server and point to mxrouting.net addresses. The exact hostnames and priorities are shown in your Control Panel for your domain — always use the values listed there.

TypeNamePriorityValue
MX@10(your-server).mxrouting.net
MX@20(your-server)-relay.mxrouting.net

SPF Record

Add a single TXT record at your root domain with the following value:

v=spf1 include:mxroute.com -all

DKIM Record

DKIM uses a unique key for each domain. Find your domain's DKIM record in the Control Panel under your domain's settings, then add it as a TXT record at the host shown (typically x._domainkey).

x._domainkey.yourdomain.com   TXT   "v=DKIM1; k=rsa; p=MIGfMA0GCSq..."

Go further with DMARC

Once SPF and DKIM are in place, consider adding a DMARC record to round out your domain's email authentication.

Email Client Configuration

Use mail.yourdomain.com as the incoming and outgoing server (replace yourdomain.com with your own domain). Authenticate with your full email address and its password.

ProtocolPort (SSL/TLS)Port (STARTTLS)
IMAP (incoming)993143
POP3 (incoming)995110
SMTP (outgoing)465587

Username & authentication

Your username is always your full email address (e.g. you@yourdomain.com). SSL/TLS is recommended for both incoming and outgoing connections.
