During setup, Xcode will allow you to choose the type of extension you want to create. In Xcode 13, there is a new Mail Extension template that will get you started on creating a new Mail Extension target. You start by adding a new target to an existing macOS App.
MAC MAIL PLUGINS HOW TO
Let's walk through how to build a compose extension. In macOS Monterey, there are four ways your extension can interact with a Mail compose window.Īn extension can validate recipient email addresses as the user is editing them, provide a view controller with additional context about the message being composed, set additional headers on outgoing messages, or alert the user of errors in the message before it is sent. Let's start with compose extensions which can provide new features for users while composing messages. Now let's dive in and learn how you can leverage MailKit APIs to build powerful extensions like the Big Secrecy Extension. When I go to view the message, there is an icon in the Message Viewer indicating that the message from Seth was encrypted and successfully decrypted by the Big Secrecy Extension. There is also an icon indicating that an extension performed an action on this message. This is because the Big Secrecy Extension performed an action to color messages regarding the Mars project as red. Oh, I received a reply from Seth, and it shows up in red in the message list. Hmm, looks like Mikey is not disclosed about our new remote office. Of course, for a project of this importance, we do want to keep our manager, Mikey, informed, so I'm going to add him. The extension was able to validate that Seth is disclosed on this project and annotates his email address with a blue checkmark. This extension provides a list of projects I'm working on, and I pick Mars Remote Office. The first thing you notice is a button for the Big Secrecy Extension in the Mail compose window.
MAC MAIL PLUGINS UPDATE
I want to send a message to my colleague Seth for an update on our new remote office on Mars. To help preserve secrecy of our projects, we are using a Big Secrecy Extension that validates recipients of a mail message. Imagine I am working for a large multinational corporation where all my colleagues are collaborating on multiple highly secretive projects. Before we dive in to build a Mail extension with these capabilities, let's go through an example of one in use. They are stable and will continue to work as the OS and Mail app change over time.
MAC MAIL PLUGINS FULL
This provides a full suite of Mail extensions to help compose messages, take action on incoming messages, block undesired mail content and provide encryption and decryption. Finally, message security extensions can provide further security by signing, encrypting, and decrypting messages when people send and receive mail. Content blocking extensions provide WebKit content blockers for Mail messages. Action extensions help people manage their inbox by providing custom rules on incoming messages. First, compose extensions will allow new workflows when composing mail messages. We are introducing four new ways you can extend Mail's user experience. Plug-ins will stop functioning in a future macOS release. Mail extensions are the future of extending Mail.
MAC MAIL PLUGINS MAC
Like other app extensions, they can be in any properly signed Mac app, can be bundled in your existing apps, and can also be distributed in the App Store. MailKit APIs are well documented and will be supported across major macOS releases. They are built with user privacy and security in mind in mind from the ground up. These extensions are built on the same underlying foundation as other app extensions like Safari app extensions and share sheet extensions. In macOS Monterey, we are shipping a new framework, MailKit, for building Mail extensions. I'm Abhilash, and along with my colleague, Seth, we are going to walk you through how to build great Mail app extensions.
Mail is a crucial application, and Mail app extensions will let you enhance it in some incredible new ways.
