Hi,
Got my network team to allow me port 53 to another dns resolver1.opendns.com (
entered this into my resolv.conf ) and get similar results,
Nov 18 14:20:32 obeml1 postfix/smtp[21362]: [ID 197553 mail.info] AAC73239403:

dsn=4.4.3, status=deferred (Host or domain name not found. Name service error
for name=eurocommerce.ie type=MX: Host not found, try again)
however i also get poor resuls from manual dig on the server ( solaris 8 )

The other mail server in my mail cluster has a later dig and still fails,

I'm suspecting something OS now is broke - not postfix -
This is only an issue where remote DNS has typo on the mx record.
Thanks
Laurence

You need to test with a different up-stream DNS server.
