As part of WWDC this week, Apple introduced a new MailKit framework for macOS Monterey that enables developers to create Mail app extensions that block content, perform message and composing actions, and help with security.
There will be four main categories of Mail app extensions, according to Apple:
- Compose: Extensions that provide new workflows when composing emails
- Actions: Extensions that apply custom rules to incoming emails, such as an email being color coded, moved to a separate inbox, marked as read, or flagged
- Content Blocking: Extensions that serve as WebKit content blockers for emails based on specific criteria in an email's HTML code
- Message Security: Extensions that sign, encrypt, and decrypt emails when sending and receiving mail, with signed and encrypted icons below emails
In the WWDC session, Apple indicated that older Mail app plug-ins will stop functioning in an unspecified future macOS release.
macOS Monterey is available now in beta for developers, with a public beta to follow in July.
