I am sure you did
dig that.other.mail.org MX.
Then the answer can't be different among postfix and command prompt.
If the two resolv.conf are identical. If need be (and some will jump
into my face) our little helper is 'cp' for identical results (and
resolvers) to get some mails delivered as long as the resolution on the
command line is satisfying. (That's what I did on Monday morning when
the queue was overflowing and the dreaded warning about them being
different came up. Luckily, here 'cp' worked.)
And I still have the desire to understand, why the resolvers could
become different over the weekend; when the name resolution(s) for MX
failed. I can't believe 'because of' the MX reolution(s) failed, and
yet/var/spool/postfix/etc/resolv.conf was just empty.
'Restart' had not helped. Only when the resolution was back, would the
two be identical again. Very strange.
