There is are easy procmail recipes to have ALL your mail copied to a
mailbox file BEFORE your experimental new receipes destroy your mail.

One way is to use a procmail recipe like this:

# Put a copy of all incoming mail into mailbox 'backup_mail'
:0c
backup_mail


Pretty easy, eh?
Just make sure this recipe gets interpretted first.
