Message rules don't work, but if message forwarded, it does???

Is the server natted? Does it have a real public IP address or is it port
forwarded from another server?

Can you follow the chain of the headers back on both a missed message and
after it has been forwarded to you?

I am still leaning toward this being some sort of trust path issue in
spamassassin, although it could be a net timeout. The lookup might time out
just before the result comes back, and on the resend the lookup is in the
local cache and hits. Have you tried setting your spammassassin timeouts longer?

Do you have any full examples of a missed message, and one that hits right
afterwards? Either full queue files or complete RFC 822 (2822) messages.

MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
