Hi list, I have noted over the last week or so my DNS servers are dumping lots of messages for bogus domain lookups. Examining the postfix queue with postqueue -p: I see many (Host or domain name not found. Name service error for name=bdgiedjhea.po6e4ina.com type=MX: Host not found, try again) Jake@bdgiedjhea.po6e4ina.com My question - why does this stay in the message queue - why not dumped back with message undeliverable or dropped?

It will be after 5 days or something. DNS errors get temp failed in case they start working again later. This is a good thing.
