QMail's Relay Filters Allow SPAM? 14
ynotds asks: "Our low profile, security-conscious specialty hosting service might have been relaying spam from an untraceable IP for around 43 hours before we tracked the source of a significant traffic increase across quite a few of our less active client IPs. After we firewalled the first spammer IP, three more appeared in quick succession trying the same thing, then after we took qmail down for a while and brought it back up, another group of four tried the same trick, all but one from 203.x.x.x IPs like our own. We now have 90Mb of mainly these unsent messages in our (appropriately named) mess directory queues, but don't want to get side tracked into duplicating others' research if this is a better known problem than it appears to be after another scan of anti-spam resources."

this wouldn't stop inbound spam to mail domains you host, but it would stop you from being an open relay.

I was just pissed he blamed qmail for a fault of his own and worse, posted it to a public server.
