On macOS 10.14 and later, you need to tell the system if you want applications
to be able to control other applications via automation or to access their
data. For example:
- In order to train messages in Apple Mail (and to filter messages in
other mailboxes), SpamSieve needs to be able to control Mail.
- When using the Apple Mail plug-in, SpamSieve needs full disk access to
install the plug-in for Apple Mail and to communicate with Mail. It
also needs to control Mail to activate, deactivate, and uninstall the
Apple Mail rule.
- In order to filter and train messages in Outlook, SpamSieve needs to be
able to control Outlook.
- Airmail and MailMate need to control SpamSieve to send it messages to
analyze.
- In order to allowlist messages from your Outlook or Entourage address
books, SpamSieve needs to control those applications to ask them about
your addresses.
- In order to flash a PowerMate when new messages arrive, SpamSieve needs
to be able to control the PowerMate app.
