Mail index breaks at login after portable home sync
I have an iMac and a MBP that are synced as portable home directories. Since I upgraded to Lion, when I switch machines (after syncing, of course), Mail always indicates that the index is broken and needs to be repaired. A process that takes 15 minutes at least.
I'm a bit at a loss because the portable home sync runs without errors...
Thanks for helping out.
iMac, Mac OS X (10.7)
