For example, every message that you receive from this list (and every other sanely configured mailing list) will have an apache.org address in the MAIL FROM, and the sender in the From:. That's because apache is remailing, and should receive all DSN's, but they are not the originator of the message. There's quite a few other scenarios where mismatches occur outside of spam. Perhaps you should look more closely at your nonspam email.
