I picked one of our log files at random, which covers a weeks worth of
email. In that time:

1) Pre-spam filters rejected 229,000 emails
2) Rejected 41,900 emails as spam
3) Blocked 1,500 malicious attachments
4) Accepted, but tagged as potential spam 3,400 emails
5) Accepted 52,400 legitimate emails, of which 39,500 originated from
OSS projects including ourselves

The number for OSS projects is probably higher - I only picked out the
ones I could quickly see.

Only 12,900 legitimate emails of what the spam filter handles didn't
originate from OSS projects. After excluding those emails, our spam
filter rejects as spam around 76% of the email it sees - and that's
ignoring what is blocked before it gets to the spam filter.

So yes, our filters annihilate the vast majority of crap before anyone
ever sees it.
