How to Set Up ICTechMail Email in Apple Mail (Mac, iPhone, iPad)

Apple Mail is the default email client on every Mac, iPhone, and iPad. If you use ICTechMail for your business email, adding your custom domain account to Apple Mail takes just a few minutes. This guide walks you through the setup on every Apple device, plus CalDAV and CardDAV configuration for calendar and contact sync.

What You Need Before You Start

Before configuring Apple Mail, make sure you have the following ready:

• Your full ICTechMail email address (e.g., you@yourdomain.com)
• Your ICTechMail email password
• Your domain must already be added and verified in your ICTechMail dashboard

Here are the server settings you will use across all Apple devices:

Setting	Value
Incoming Server (IMAP)	smtp.swiftthinkr.ai
IMAP Port	993
IMAP Security	SSL/TLS
Outgoing Server (SMTP)	smtp.swiftthinkr.ai
SMTP Port	587
SMTP Security	STARTTLS
Username	Your full email address
Password	Your email account password

2. In the menu bar, click Mail then Add Account (or go to System Settings > Internet Accounts > Add Account).
3. Select Other Mail Account and click Continue.
4. Enter your Name, full ICTechMail email address, and Password. Click Sign In.

3. Tap Add Account then Other.

Troubleshooting Common Issues

Authentication Failed / Cannot Verify Account

This is the most common issue during setup. Here is how to fix it:

• Double-check your password. The password is for your ICTechMail email account, not your ICTechMail dashboard login (they may differ if you changed one separately).
• Use your full email address as the username. Enter you@yourdomain.com, not just you.
• Make sure the account exists. Log in to your ICTechMail dashboard and confirm the email account is created and active under your domain.

Cannot Send Email (SMTP Error)

If you can receive email but cannot send, check these settings:

• Outgoing server must be smtp.swiftthinkr.ai on port 587 with STARTTLS enabled.
• Authentication must be turned on for the outgoing server. Apple Mail sometimes defaults to "no authentication" for SMTP \u2014 change it to Password.
• Make sure the SMTP username and password are filled in (same as your incoming credentials).

SSL Certificate Errors

If you see a warning about the server certificate:

• Make sure you are using smtp.swiftthinkr.ai as the server \u2014 not your own domain name. The SSL certificate is issued for smtp.swiftthinkr.ai, so using any other hostname will trigger a mismatch warning.
• If prompted, tap Continue or Trust to accept the certificate. This is safe when connecting to smtp.swiftthinkr.ai.

Email Not Syncing or Slow to Update

• On iPhone/iPad, go to Settings > Mail > Accounts > Fetch New Data and set your ICTechMail account to Push or Fetch every 15 minutes for faster updates.
• On Mac, go to Mail > Settings > Accounts, select your ICTechMail account, and set Check for new messages to Automatically.
• Make sure you have a stable internet connection. IMAP requires an active connection to sync.

Calendar or Contacts Not Syncing

• Verify that your CalDAV/CardDAV server is set to smtp.swiftthinkr.ai (not https://smtp.swiftthinkr.ai \u2014 the device adds the protocol automatically).
• On iPhone, go to Settings > Calendar > Default Calendar and make sure it is set to your ICTechMail calendar if you want new events to save there.
• On Mac, open Calendar > Settings > Accounts and click Refresh Calendars to force a sync.

Summary of All Server Settings

Service	Server	Port	Security
IMAP (Incoming)	smtp.swiftthinkr.ai	993	SSL/TLS
SMTP (Outgoing)	smtp.swiftthinkr.ai	587	STARTTLS
CalDAV (Calendar)	smtp.swiftthinkr.ai	443	SSL/TLS
CardDAV (Contacts)	smtp.swiftthinkr.ai	443	SSL/TLS

All services use your full ICTechMail email address as the username and your email account password for authentication.
