Hi, again, The random word spams: Do they all have message IDs starting "CHILKAT-MID" ? The three samples Michael sent me had that, and I found this on Google: http://www.google.com/support/forum/p/gmail/thread?tid=7aa0d643adde28a1&hl=en Anyway... might be worth a rule if it turns out that Message-ID format is consistent.
