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@xxxxxxxxxxxxxxxxxxxxxxx
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.
  

Agreed, however this opens a potential DoS attack vector - I'm trying to determine why my postfix even has these requests present as I'm not initiating the emails (as far as I know) and I do not forward emails for any other domains.
I feel like I'm missing something......confused maybe
