macOS Mail Auto Configuration
Provides a tutorial example on how to configure macOS Mail to automatically detect and select POP and SMTP services from the mail server.
What Is macOS Mail?
macOS Mail is the built-in email client tool on your macOS computer.
Configuring macOS Mail to work with Postfix and Dovecot servers
is pretty easy, if you are providing services with their default port numbers.
For example, my email server supports the standard services on default ports:
- SMTP service on port 25, with STARTTLS (Opportunistic TLS) and no authentication.
- SMTPS service on port 465, with SSL/TLS and no authentication.
- SMTP Submission service on port 587, with STARTTLS (Opportunistic TLS) and no authentication.
- POP3 service on port 110, with STARTTLS (Opportunistic TLS) and normal username/password authentication.
- POP3S service on port 995, with SSL/TLS and normal username/password authentication.
- IMAP service on port 145, with STARTTLS (Opportunistic TLS) and normal username/password authentication.
- IMAPS service on port 993, with SSL/TLS and normal username/password authentication.
- Email server address is 192.168.1.100.
- Email address is firstname.lastname@example.org.
- Username and password associated with the email address: herong and TopSecret.
So here is what I did to configure macOS Mail with above server settings.
1. Launch Mail app from the launchpad.
2. Click "Mail > Add Account" menu.
You see a list of popular email service providers.
3. Select "Other Mail Account" and click "Continue".
You see a small dialog box.
4. Enter your name, email address and password.
And click "Sign In".
It will try and display an error: "Unable to verify account name or password".
More settings are displayed at the same time.
5. Enter the following extra settings:
User Name: herong
Account Type: POP
Incoming Mail Server: 192.168.1.100
Outgoing Mail Server: 192.168.1.100
6. Click "Sign In" again.
It will try and display a certificate exception:
"Mail can't verify the identity of the server 192.168.1.100".
7. Click "Continue" accept the exception.
You should be able to send new emails and retrieve emails now.
