How to install (Mojave onwards)

1. Build the project or download it from Github releases
2. In the Finder, open /tmp/Gmailinator and ~/Library/Mail/Bundles
3. Copy the GMailinator.mailbundle folder from /tmp/Gmailinator to ~/Library/Mail/Bundles
4. In mail, open Preferences -> General -> Manage Plug-ins, and enable Gmailinator.
5. You will be prompted to restart Mail

Allow usage in Big Sur

1. Codesign the bundle

codesign -s "<Replace with the identity>" -v -f GMailinator.mailbundle/

Alternatively, you can enable "Automatically manage signing" in Xcode:

• Under the "Signing and Capabilities" tab (find this by clicking GMailinator root in sidebar)
• Check "Automatically manage signing"
• Change "Team" dropdown. You'll need to do some setup if you don't have a team
• Now mail bundle will automatically be signed on Xcode build

2. Allow in system policy

spctl --add ~/Library/Mail/Bundles/GMailinator.mailbundle

Credits

A lot of this was built with heavy use of of the BindDeleteKeyToArchive project by Ben Lenarts. The Xcode project and interface skeleton were all from that project, and for the most part, renamed. I added the keybinding code.

A lot of the code is also either copied in whole, or modified from the Nostalgy4Mail.app project, by Hajo Nils Krabbenhöft, and subsequently by Jelmer van der Linde. I've added support for ARC (turns out there were quite a few leaks), and prettied-up (imho) the move-to-folder dialog.
