Re: A rule to copy all message to a maildir, and then keep processing

Another approach would be to use an includerc, which only delivers to the 
backup mailbox if a variable isn't set.  Roughly:
:0
* BACKEDUP ?? ^^^^
{
        BACKEDUP=YES
        :0c:
        backup.mbx
}

If you're identifying lists before spam filtering, then within the scope of 
having identified it to be a list message (say, after using list_id.rc), 
you can INCLUDERC=backup.rc, then continue to process for specific list 
messages.  Likewise, if you have a greenlist, after verifying the sender is 
in your greenlist, INCLUDERC=backup.rc, then handle the specifics of 
storing the greenlisted message.  If it is neither, you should process for 
spam, discard spam, and afterwards, INCLUDERC=backup.rc
Not elegant, but if any of the recipies bail out without explicit delivery 
and you continue to process the procmailrc, because the message has already 
been backed up, it won't be re-backed up by a seperate "call" to backup.rc.
Of course, if you simply process for spam FIRST, then backup everything 
that isn't spam, it is a lot cleaner.
