In our experience, this is primarily spamware. You surely don't
really want to hear from that pondlife, do you?

2004-03-15 09:24:00 SMTP protocol violation: synchronization error
(next input sent too soon): rejected "MAIL FROM:<6326gl@???>"
H=c-24-6-198-61.client.comcast.net (24.6.198.61) [24.6.198.61]

[look-up 24.6.198.61 at http://openrbl.org if you're uncertain
about their status...]

If there's someone you want to hear from who's breaking the protocol
in this way, then - for their own benefit too - you should be pointing
out to them that their behaviour is unacceptable and they need to fix
it. There's plenty of other potential recipients who will treat their
behaviour as hostile - they need to know that.

IMHO and YMMV, contents may settle in transit, etc.
