The intended use is to create a backup from a mailbox through IMAP,
which is as close as possible to the original mbox file, thus resembling
the FROM lines as well.

The envelope sender address does not drop it's meaning after delivery.
It's required for debugging purposes, writing mail filters, create
blacklist filters from detected spam, etc.
