Is there anyway I can get a report directly from Postfix about how many emails were sent per day, or other similar statistics? As a "out of the box" solution?
I'm not sure what your "directly from Postfix" requirement is, but I'll offer pflogsumm.pl as an option. It just runs via cron and parses through your mail logs, generating aggregate statistics as it goes.
