Not sure, I personally think that moving them silently makes errors harder to diagnose. I'll add an option since then you can set this option (antispam_missing_signature = [error|move]) to move after you've tested and verified that it works just fine.

Try this patch please, I have only compiled it so far. (there might be rejects in the signature-log.c file unless you update to the current git tree but you don't care about that)
