Troubleshooting Sending Issues with Apple Mail and Mailcow Server

'Mac SMTP'

As an Apple user, you might be familiar with the default email client, Mail, which comes pre-installed on your Mac. However, some users have reported issues sending emails through their Mailcow server using this client. If you're experiencing similar problems, don't worry; we're here to help you troubleshoot and find a solution.

In my case, I encountered an issue where Apple Mail couldn't establish an SMTP connection to the Mailcow server, resulting in failed email sending attempts. The problem seemed unrelated to the Apple logs or configuration files, as they didn't provide any clues. It appeared that the issue was related to how my Mac connects to Mailcow.

To resolve this issue, I took a step-by-step approach and checked various aspects of the connection:

1. IMAP Access: Ensure that IMAP access is enabled in your Zoho Mail interface.

2. ISP Port Blocking: Check with your Internet Service Provider (ISP) if they have blocked any ports that might be affecting your email sending capabilities.

3. Apple Config Profile: Try reinstalling the profile using the Apple config profile to see if it resolves the issue.

4. Active Ban on Mailcow UI: Clear any active bans on the Mailcow User Interface to ensure there are no restrictions blocking your emails.

After checking these aspects, I found that the issue was not with the server or provider but rather with my Mac's configuration. Specifically, I discovered that the SMTP connection was failing due to a port issue. Here's how you can resolve it:

1. SMTP Server Settings: Go to Apple Mail's preferences and click on the 'Accounts' tab.

2. Account Information Tab: Under this tab, select the email account experiencing issues.

3. Edit SMTP Server List: Click on the 'Edit SMTP Server List' button and then click on the 'Advanced' tab.

4. Port 995 and SSL: Ensure that Port 995 is selected, and Use SSL is enabled for authentication.

By following these steps, you should be able to resolve the issue with your Apple Mail client not sending emails through the Mailcow server. Remember that SMTP is a dedicated protocol for sending emails, and most email clients rely on it to push or send messages.

In conclusion, if you're experiencing issues sending emails using Apple Mail and your Mailcow server, try checking the IMAP access, ISP port blocking, and active ban on the Mailcow UI. If none of these solutions work, ensure that the SMTP connection is configured correctly by following the steps outlined above.
