New versions of MsgFiler Engine 1.1.7 and the Original MsgFiler Mail Plugin 2.2.2 have been released. These bring support for OS X 10.9.1, which was released earlier today.
It is common for OS X updates to disable your Mail plugins. To get back fast-filing performance with MsgFiler 3, simply:
- Download the latest version of the plugin.
- Decompress the ZIP archive.
- Double-click on the disk image file.
- Go to the Finder.
- Hold the option-key down and click on the Go menu.
- Choose Library.
- Navigate to the
~/Library/Mail/Bundlesfolder. - Drag the
MsgFilerEngine.mailbundleorMsgFilerPlugIn.mailbundlefolder into the Bundles folder. - Quit and relaunch Mail.
Verify that the plugin is active by clicking on the Message menu:
- MsgFiler Engine: A menu item labelled “MsgFiler Engine 1.1.7” will appear at the bottom of the Message menu.
- Original MsgFiler Mail Plugin: A menu item labelled “Move with MsgFiler” will appear at the bottom of the Message menu.

Might it be possible to allow us to use keyboard shortcuts (that are programmable) to select whether
we want to “Show”, “Copy” or “Move” to the mailbox/folder selected?
I know that the return key maps to the default but
I often want to copy and move as well as show
and I’d like to avoid having to use the mouse/trackpad.
Thanks.
Keyboard shortcuts already exist for these commands. Click on the Gear icon in the upper-right to see them.
Command-o = open mailbox
Command-shift-c = copy to mailbox
Command-shift-m = move to mailbox
