Solution 02. Minimize The Amount Of Space The Mail Application Utilizes

Now, in this article for how to clear Mac Mail cache, let’s talk about minimizing the amount of space the Mail app uses. The folder for Mail becomes very large because the app itself downloads each email you have. It includes downloading the attachments. These are stored within your Mac. Thus, the email and attachments can be accessed offline. And, they are also indexed within Spotlight so you can search for them easily. The problem is, if you have a lot of emails with big attachments, you may take up a lot of space on your Mac computer. This will slow down your device.

Before, there was a way where you can reduce the amount of space taken up by your email cache. This is by changing the option to keep messages for offline viewing to that of “Don’t Keep”. However, this option is now removed within Mac OS X Mavericks. It is not available in the latest macOS operating systems. Thus, there isn’t a way to control your Mail app in terms of downloading a reduced amount of messages for offline viewing.

But, there’s a way around this. In this article on how to clear the Mac Mail cache, we will tell the Mail app itself to stop grabbing the attachments for offline use. You do this by launching the Mail app. After that, you go to the Mail menu. Then, you select the option for Preferences. The next step would be to click the icon for Accounts. After that, choose the specific account where you want to change preferences. Click the tab for Advanced. Then, uncheck the option that says “Automatically Download All Attachments”.

In this way, attachments aren’t downloaded automatically. However, they are still stored online. Thus, it will help free up storage space within your computer. Another thing you can do is to control the number of messages that the app downloads through the server settings within the server of your email. For instance, within Gmail, you can change a setting that allows you to “hide” your emails from the application called Mail. You can also use this setting to hide messages within other email clients that gain access to it through IMAP.

To do this, you have to follow the steps below:

  1. Launch Gmail on the web interface. The first step would be to launch Gmail within a web interface. Then, press the menu that looks like a gear.
  2. Choose Settings. The next step would be to choose Settings. Then, choose the tab that says Forwarding and POP/IMAP.
  3. Select Size Limits. Within the Folder section, you should choose Size Limits.
  4. Choose the right option. Then, you should select the option that says IMAP folders will have a certain limit of a number of messages to see.

Sometimes, other email services provide the same settings to edit. In addition, you can also stop your Mail app from utilizing IMAP. Then, you can change its settings to utilizes POP3 and that of SMTP to send and receive email messages.

After that, it would be possible to delete your email from the Mail application. They will be removed from your computer. However, they won’t be removed from the server of your email. It is important to note that POP3 is not a great system in terms of modern email. However, this gives you the ability to get email notifications within the Mail app. In addition, it also allows you to send your messages using it. This is done while making sure the archive is left on the email server alone.
