from ChangeLog:
-previously, for safety, getmail would re-retrieve messages after a session
that encountered errors. However, getmail had enough information to safely
remember those messages that had been successfully delivered. This behaviour
has been changed, to avoid delivering duplicate messages where it isn't
necessary. Thanks: Thomas Schwinge.
-in output/log files, getmailrc files are now specified only by filename,
instead of by complete paths. This will prevent some overly-long output
lines.
