[ale] Monitoring outgoing emails on Postfix, filtering incoming bounce back messages

[Warren Myers]

A thought: you may be able to grep for just 'undeliverable' or 'bounce'

It's also possible the mail isn't being sent through your server: at a
previous $WORK, we had intermittent gushes of undeliverable email, that when
you scanned the headers, wasn't even related to our domain, but the
reply-to: or from: fields were being spoofed.
