I run getmail + maildrop to get all mails locally, but every time getmail runs, it will download a copy of all messages. even setting delete option in getmail or mailfilter config does not help
the related config:
[options] verbose = 5 read_all = 0 delete = 0
/usr/bin/reformail -D 8000 $HOME/.getmail/duplicate.cache
if ( $RETURNCODE == 0 )
exit
