Hello aaron,

1) If you can remove the well transfered messages on host1 then use
the --delete --expunge1 options but REMOVE the --delete2 option
from your command line. This way the messages from host1 will be
transfered to host2 and removed from host1.

2) Instead of using the qad script adjust_time.pl you can can simply
use the option --syncinternaldates:

imapsync ... --delete --expunge1 --syncinternaldates
