4. Select the email account you want to change the outgoing port for.
5. Click on the "Advanced" tab.
6. In the "Outgoing Mail Server" section, click on the "Edit" button next to "SMTP Server".
7. In the "SMTP Server" window, click on the "Port" dropdown menu and select the new port number you want to use (e.g., 587 or 2525).
8. Click "OK" to save the changes.

Method 2: Using an email client like Apple Mail or Microsoft Outlook

1. Open your email client (e.g., Apple Mail or Microsoft Outlook) on your iMac.
2. Go to the "Accounts" or "Preferences" section of your email client.
3. Select the email account you want to change the outgoing port for.
4. Look for the "SMTP" or "Outgoing Mail Server" settings and click on the "Edit" or "Configure" button.
5. In the "SMTP" or "Outgoing Mail Server" window, click on the "Port" dropdown menu and select the new port number you want to use (e.g., 587 or 2525).
6. Save the changes to your email client.

Common outgoing mail ports:

• Port 25: The default outgoing mail port, which is often blocked by ISPs and email providers due to spam concerns.
• Port 587: A common alternative outgoing mail port that is often used for secure email transmission.
• Port 2525: Another alternative outgoing mail port that can be used if Port 25 or 587 is blocked.

Important notes:

• Changing the outgoing mail port may affect your ability to send emails. Make sure to check with your email provider or ISP to ensure that the new port is allowed.
• Some email providers may require you to use a specific port for outgoing mail, so be sure to check their documentation or contact their support team if you're unsure.
• If you're using a VPN or proxy server, you may need to configure those settings separately to ensure that your outgoing mail traffic is routed correctly.
