With 2.3.12+ you can use 

metric imapc_traffic {
  filter=event=imap_command_finished
  fields=bytes_in bytes_out
  group_by=user
}

or if you have 2.3.11 (or older)

metric imap_traffic {
  event_name=imap_command_finished
  fields=bytes_in bytes_out
  # group_by needs 2.3.10+
  group_by=user 
}

Then you can use `doveadm stats dump` to see these.
