My friend Rob (from Indigo Consulting) was having issues with and stopped by to find out what to do. Having had the same problem in the past, I looked up some handy dandy commands that will hopefully fix the problems (like crashing, slowness, etc.). If you’re having the same issue, or just curious, here’s what we did.

  1. Quit Mail
  2. In a Terminal window, navigate to ~/Library/Mail (cd ~/Library/Mail)
  3. Type in the following command: sqlite3 Envelope Index
  4. A sqlite> prompt will appear.
  5. At that prompt, type vacuum subjects;
  6. After a short delay, the prompt will return. Type Control-D to exit.
  7. Restart Mail and it should work!

More to come on this..
