To set up business email in Apple Mail you only need your hosting provider's IMAP/SMTP credentials and about two minutes. This guide walks you through every step, the exact values to enter, and how to fix the most common errors.
What You Need Before You Start
Gather the following details from your hosting control panel (cPanel, Plesk, or similar) under Email → Email Accounts:
- Email address: e.g.,
[email protected] - Password for that mailbox.
- Incoming server (IMAP): typically
mail.yourdomain.comon port 993 (SSL). - Outgoing server (SMTP): same hostname, port 465 (SSL) or 587 (STARTTLS).
- Username: usually your full email address.
If your host uses cPanel, click Set Up Mail Client inside the email account to see all these settings pre-filled.
Step by Step: Adding the Account in Apple Mail
1. Open the Add Account Wizard
Open Mail on your Mac. In the menu bar go to Mail → Add Account… (or the wizard appears automatically the first time you launch Mail).
From the provider list choose Other Mail Account… and click Continue. Do not choose Google, Exchange, or iCloud unless your mailbox is actually hosted on those platforms.
2. Enter Your Name, Address, and Password
Fill in the three fields:
- Full Name: what recipients will see, e.g. Ana López — MyCompany.
- Email Address:
[email protected]. - Password: the password for this mailbox on your hosting account.
Click Sign In. Mail will try to detect server settings automatically. If it fails (you see "Unable to verify account name or password"), click Next to enter them manually.
3. Configure the Incoming Server (IMAP)
On the manual configuration screen choose IMAP as the account type (recommended over POP3 because it keeps all your devices in sync).
| Field | Typical value |
|---|---|
| Mail Server | mail.yourdomain.com |
| User Name | [email protected] |
| Password | Your password |
Click Sign In. If the server uses a self-signed SSL certificate macOS will show a warning; accept it only if you recognize your hosting provider's server name.
4. Configure the Outgoing Server (SMTP)
Next, Apple Mail asks for your SMTP settings:
| Field | Typical value |
|---|---|
| SMTP Server | mail.yourdomain.com |
| Port | 465 (SSL) or 587 (STARTTLS) |
| User Name | [email protected] |
| Password | Your password |
Enable Use SSL (or TLS depending on your macOS version). Click Sign In, then Done.
Verifying Everything Works
Once the account is created, run two quick tests before using it in production:
- Receive: send yourself a test email from Gmail or any external account. It should appear in your inbox within seconds.
- Send: compose a message from Apple Mail to an external address and confirm it arrives without landing in spam.
If outgoing messages end up in the recipient's spam folder, the issue is usually in your domain's DNS records (SPF, DKIM, DMARC), not in Apple Mail itself. Contact your business email provider to verify those records.
Troubleshooting Common Errors
"Cannot connect to the server"
Double-check the server hostname for typos or accidental spaces. Confirm the port: 993 for IMAP with SSL, 143 for IMAP with STARTTLS. If you're on a VPN, try disabling it temporarily.
"The server requires authentication"
In Mail Preferences → Accounts → your account → Outgoing Mail Server (SMTP) → Edit SMTP Server List, make sure Authentication is set to Password and the username is your full email address, not just the local part before the @.
Duplicate emails or folders not syncing
Go to Mail → Preferences → Accounts → Mailbox Behaviors and ensure Sent, Drafts, and Trash point to actual server-side IMAP folders, not local-only ones.

Key Takeaways
- Always use IMAP instead of POP3 to keep your inbox in sync across all devices.
- The secure ports are 993 (IMAP) and 465 or 587 (SMTP).
- The SMTP username must be your complete email address.
- If messages land in spam, the root cause is SPF/DKIM/DMARC DNS records, not Apple Mail.
- Mail's auto-detection can fail with shared hosting — entering settings manually always works.

FAQ
IMAP or POP3 for Apple Mail?
Always IMAP. POP3 downloads messages to your Mac and removes them from the server, making them inaccessible from your phone or any other device. IMAP syncs everything in real time.
Can I add multiple business accounts in Apple Mail?
Yes, with no limit. Repeat the process for each account. You can view them all in a unified inbox or separately using the sidebar.
What if Apple Mail asks for a verification code?
That happens with Google Workspace or Microsoft 365 accounts. In those cases you must authenticate via OAuth (the "Sign in with Google" or "Microsoft" button), not with direct IMAP username and password.
Does this work on macOS Sonoma and Sequoia?
Yes. The steps are identical on macOS Monterey, Ventura, Sonoma, and Sequoia. Only minor visual differences in menu placement exist — the logic and fields are the same.
