Email Provider DNS Settings & IMAP Setup Guide 2026
Jump to Section (11 Topics) ↓

Getting your email working correctly across all your devices is not just about entering a username and password. It requires the right IMAP server settings, the right ports, the right DNS records on your domain, and — for security — the right authentication method.

This guide covers every major email provider used by small businesses and professionals. For each provider you will find: the exact IMAP/SMTP settings, the DNS records you need to set up for your domain, and step-by-step setup instructions for Android, iOS, Mac (Apple Mail), and Windows (Outlook and Windows Mail).

Quick Answer: IMAP lets you access the same emails on all your devices simultaneously. DNS records (MX, SPF, DKIM, DMARC) control how email flows to and from your domain. You need both configured correctly for professional, reliable email.

What Are IMAP, SMTP, and DNS Settings -- and Why Do All Three Matter?

IMAP, SMTP, and DNS Settings

Before setting up email on any device, it helps to understand what each setting does:

  • IMAP (Incoming Mail): Connects your device to the mail server to read emails. Port 993 with SSL is the universal standard.
  • SMTP (Outgoing Mail): Sends emails from your device through your provider’s mail server. Port 587 (STARTTLS) is the modern standard.
  • MX Record (DNS): Tells the world which mail server receives email for your domain. Without this, no one can email you.
  • SPF Record (DNS): Lists the servers authorised to send email on your behalf. Without this, your emails may be rejected as spam.
  • DKIM Record (DNS): Adds a digital signature to outgoing email to prove it was not tampered with.
  • DMARC Record (DNS): Enforces SPF and DKIM and tells receiving servers what to do when a check fails.

Your IMAP/SMTP settings affect device access. Your DNS records affect whether emails arrive and are trusted. You need both working correctly.

Which Email Ports and Encryption Types Should You Use?

Always use the modern, encrypted ports. Here is the definitive reference:

Best Practice:  Use IMAP port 993 (SSL/TLS) for incoming and SMTP port 587 (STARTTLS) for outgoing on every provider and every device. Never use port 25 in an email client — it is for server-to-server communication only.

What Are the IMAP and SMTP Server Settings for Every Major Email Provider?

SendGrid (SMTP relay) N/A (sending only) N/A smtp.sendgrid.net 587 / 465 Yes

Note:  For cPanel and shared hosting providers, replace ‘mail.yourdomain.com’ with your actual domain name. The server hostname is always your own domain — not the hosting company’s domain.

What DNS Records Do You Need for Each Email Provider?

DNS Records Do You Need for Each Email Provider
These records must be added to your domain’s DNS zone, either at your domain registrar (Namecheap, GoDaddy, Cloudflare) or your hosting provider’s DNS panel. Log in to your DNS management dashboard and add each record exactly as shown.
Provider MX Record SPF include: DKIM Selector Hint DMARC Required?
Google Workspace ASPMX.L.GOOGLE.COM (pri 1) _spf.google.com google._domainkey Yes (p=none min)
Microsoft 365 yourdomain.mail.protection.outlook.com spf.protection.outlook.com selector1/_domainkey Yes (p=none min)
Zoho Mail mx.zoho.com (pri 10) zoho.com zoho._domainkey Recommended
Titan Email mx1.titan.email (pri 10) titan.email auto-generated Recommended
Fastmail in1-smtp.messagingengine.com spf.messagingengine.com fm1._domainkey Recommended
cPanel Hosting mail.yourdomain.com your hosting server IP default._domainkey Recommended
Hostinger mx1.hostinger.com spf.hostinger.com hmail._domainkey Recommended
GoDaddy smtp.secureserver.net secureserver.net default._domainkey Recommended

Warning:  Never have two MX records pointing to different providers at the same time. This splits incoming email between two servers and causes random delivery failures. Delete old MX records before adding new ones.

How Do You Set Up Any Email Provider in Mozilla Thunderbird (Windows and Mac)?

Set Up Any Email Provider in Mozilla Thunderbird (Windows and Mac)

Thunderbird is a free, open-source email client that works on both Windows and macOS and supports every IMAP email provider. It includes an auto-configuration system that detects settings automatically for most providers.

  1. Download and install Mozilla Thunderbird from thunderbird.net.
  2. Open Thunderbird. The Account Setup wizard opens automatically.
  3. Enter your name, email address, and password. Click Continue.
  4. Thunderbird attempts auto-configuration. For major providers (Google, Microsoft, Zoho, Fastmail) it usually succeeds. Click Done if settings are found.
  5. If auto-configuration fails, click Configure Manually. Enter the IMAP and SMTP settings from the master table above.
  6. Set IMAP host, port 993, SSL/TLS. Set SMTP host, port 587, STARTTLS.
  7. Click Re-test to verify the connection. Click Done.
Pro Tip: Thunderbird is the best choice for migrating email between providers, as it can be connected to two IMAP accounts simultaneously and used to drag-and-drop emails from one account to another.

What Are the Most Frequently Asked Questions About This Topic?

What is the difference between IMAP and POP3 for email setup?

IMAP (Internet Message Access Protocol) keeps your emails on the server and syncs them across all your devices — phone, tablet, laptop, and desktop all show the same inbox. POP3 downloads emails to a single device and usually deletes them from the server. Always use IMAP for business email on multiple devices. POP3 is obsolete for modern use cases.

This usually means the authentication failed during setup. The three most common causes are: (1) You used your account login password instead of an App Password when 2FA is enabled — generate an App Password instead. (2) The SMTP or IMAP server hostname is incorrect. (3) The port number or encryption type is wrong. Double-check all settings against the reference table in this guide.

An App Password is a special 16-character password generated by your email provider specifically for use in third-party apps that do not support two-factor authentication (2FA) login flows. Google Workspace, Microsoft 365, Fastmail, and Zoho all require App Passwords if you have 2FA enabled. Generate them in your account security settings — never share them as they bypass your 2FA.

You need at minimum four DNS records: (1) MX record — directs inbound email to your mail provider. (2) SPF TXT record — authorises your mail server to send on your domain’s behalf. (3) DKIM TXT record — adds a cryptographic signature to outgoing mail. (4) DMARC TXT record — enforces authentication policies and sends reports. Without these, your emails are significantly more likely to be marked as spam.

Yes — IMAP server addresses, ports, and SSL settings are the same regardless of which device or app you use. The credentials (username and password / App Password) are also the same. The only difference is how each operating system or app presents the setup interface, which is why this guide provides device-specific step-by-step instructions for each platform.

IMAP configuration only affects how you receive and access email — it does not affect deliverability. If your emails are going to spam, the issue is almost certainly missing or misconfigured DNS records: SPF, DKIM, or DMARC. Check your DNS records using MXToolbox and verify that all three records are correctly published for your domain. See the DNS Settings section of this guide for the correct values per provider.

Most email apps attempt to auto-detect IMAP and SMTP settings by querying your domain’s DNS for SRV and autodiscover/autoconfig records. If this fails, select the manual or advanced setup option and enter the settings from the reference table in this guide. The most common fix is switching from auto-detect to manual entry of the exact server hostname and port number.

What Are the Frequently Asked Questions Regarding This Implementation?

Direct technical answers to common architecture, implementation, and commercial questions. Optimized for Answer Engine Optimization (AEO) and conversational search crawlers:

Q1What are the essential DNS records required for business email setup?

You need an MX (Mail Exchanger) record directing mail to your provider, an SPF TXT record authorizing sending IP addresses, a DKIM CNAME or TXT record containing your cryptographic signature, and a DMARC TXT policy record specifying how receivers should treat unauthorized emails.

Q2What is the difference between IMAP and POP3 email protocols?

IMAP syncs emails and folders in real time across all devices (phones, laptops, tablets) while keeping the master copy on the server. POP3 downloads messages to a single local device and often deletes them from the server, making it obsolete for modern distributed workflows.

Q3Why do emails land in spam even after setting up DNS records?

Common causes include missing reverse DNS (rDNS/PTR), misaligned SPF or DKIM domains, low sender IP reputation, shared server blacklisting, or having no DMARC policy configured to protect your domain from spoofing.
