At the point where things stop working, what content does the whitelist table have? ie, anything recognizable or (incredibly) zero size? One possibility - a far fetched one, admittedly - is that hosts in your whitelist got themselves greytrapped (if you did set that up). > When I do: > cat /dev/null > /var/db/spamd > all starts to work again This sounds like somehow your initally whitelisted hosts got themselves blacklisted, or the whitelist is somehow bypassed. > 2.

If your malware manages to behave RFC-correctly, that is, resend after what the greylisting host considers a reasonable interval, it will manage to send whatever it's trying to send. -- Peter N. M.
