well at lest this is starting to make total sense.

i was unaware of unbound dns and not really sure that would ever work on a mail server?

even if it does elsewhere

postfix 101

postfix will always look at the resolv.conf file on a unix system.

if all you have is 127.0.0.1 (loopback) and assuming that is even attached to unbond dns its just an added layer that is not nessesary and in my opinion introduse resolving issues which you do seem to be having.

my final suggestion would be to correct the resolv.conf file which is what all unix software goes to when using an internal dns system call.

ie the c libraries that compile postfix (and everything else) will try to use the internal dns function calls which would always go back to /etc/resolv.conf

resolv.conf needs to point to valid dns servers (8.8.8.8 for example)

or to your own bind dns server running on the system.

these are the standard's on anything unix based.

if you really need to run unbound then i suggest that you contact there tech support or community as it is clearly a factor in your issues.

hope this helps.






Happy Tuesday !!!

As I said, I use unbound. resolv.conf only has 127.0.0.1.

Windows - where does that come in? Haven't used that in years! :)
