Log Message:
Update to 4.1.0. From the changelog:

  -biggest change is multiple verbosity levels.  To support this from rc file,
  the verbose parameter had to change from a boolean to an integer.  Update
  your getmail rc files:  for quiet, set verbose to 0.  For more output,
  set it to 1 or 2.  2 includes info about messages not retrieved, etc.
  -add rc filename to error messages
  -change fix from 4.0.11 for email module raising exception during .flatten().
  Thanks:  Jürgen Nagel.
  -some types of SSL error could cause getmail to exit instead of
  continuing to the next mail account; fixed.  Thanks:  Matthias Andree.
