If you don't care about things being reliable, then sure do whatever.
- Reading incomplete mail from the queue.
- Deleting the wrong message because Postfix reuses the file name.
- Breaking delivery status notifications with one-way replication.
None of these issues need to exist when you use the proper export
mechanisms. For example, you could set up UUCP where the inside
host polls the outside host. You could use BSMTP (see example in
master.cf) as a way to export mail in a safe way.
