Version 4.40.0
21 April 2013
    -convert SIGTERM to SIGINT so getmail can cleanup and exit normally if
    killed with a default signal.  Thanks: Carl Lei.
    -fix change which resulted in passing full protocol name to OSX keyring
    program, which can't handle it (restricted to 4-character code).
    Thanks: Tim Gray.
Version 4.40.1
22 April 2013
    -again change protocol codes passed to OSX, as they're not only reserved
    codes, but also case-sensitive.  Use the ones an OSX user reports work
    properly.  Thanks: Tim Gray.
