As --sycinternaldates don't work to sync the Email dates to which it was received. so change
Code:
--user2 username/tb
" suffix but leave off --syncinternaldates
the final imapsyn coammand would be by waving off --sycinternaldates & add --user2 username/tb suffix(/tb)
My Mail boxes are synced with Actual email receiving dates.
