| This is really strange. I have never seen something like this (except
| when the DNS is broken).
It isn't, I can get addresses for the MX records when the query
originates elsewhere - they just don't reply when it is my MTA
asking.
| Do you have any logs that demonstrate this?
That would be kind of meaningless, as all that happens is that
nothing happens - there's no difference in behaviour from what
would happen if the remote DNS server(s) were down/unreachable,
except that queries from other sources work (but my MTA is unaware
of that).
| Do you have DNSSEC validating resolver enabled or something like this?
Nothing special, not that it matters - all the queries to which
reply packets are received (like looking up the MX in the first
place) work just fine - for the ones that fail, there is simply
no answer, nothing to validate.
And once again, this has nothing whatever to do with nmh.
That is, this does not belong on this list.
