Just gone live with a new Postfix mail server, sat in front of an Exchange box for inbound mail only.
It's set up to reject email for unknown recipients, which works fine, but I want to get a log of exactly what destination email addresses have been rejected, just to be sure no domains/recipients have been missed.
I've had a Google but come up blank. Is there a decent simple way to do this?
Thanks.

pflogsumm.pl is a great application to parse and produce statistics from postfix log files.
