Subject: Re: [9fans] smtp dns failure: mx lookup

so, the question is, why does the mx lookup fail?
are your [a-j].root-servers.net entries up-to-date?
i'm not able to replicate the failure here:
; fn dns { n=() {if (~ $#* 1) n=ip; echo $* $n | 9p rdwr dns/dns}}
; dns smtp.comcast.net mx
write: dns: resource does not exist
; dns smtp.comcast.net
63.240.77.77
on a related note, is there a way to make the dns fileserver return all
the answers for a given question?

| upas *does* look up the a record if the mx lookup says the name does not exist.
| it does not look up the a record if the mx lookup fails.
