Comment (by lnicola):

 According to some subscribers to gdal-dev, Gmail greylists our messages,
 probably because they lack DKIM. Combined with our own, less discriminate
 greylisting, this causes significant delays.

 I feel less strongly these days about leaving the headers untouched vs.
 stripping and re-signing (some users don't really feel like changing their
 filtering rules), but having no DKIM is a lot worse.
