I'm running all the latest packages of Intrepid. Nothing fancy about my LAMP install. I just apt-get upgraded recently and now my PHP apps can't send email out. This is what I get in my logs:



Mar 11 18:22:26 smc-dev postfix/error[9889]: B240167C0EB: to=<gcornelisse@gmail.com>, relay=none, delay=135053, delays=135033/20/0/0.03, dsn=4.4.3, status=deferred (delivery temporarily suspended: Host or domain name not found. Name service error for name=gmail.com type=MX: Host not found, try again)


whois, nslookup, dig, and resolveip all give me normal results for gmail.com (its not just gmail.com I'm having trouble with)

I just can't figure out why postfix would have a problem and nothing else would....almost. I also noticed that when I ssh into the box there is a super long "hang" before I'm given a prompt for my user/pass. Possibly related?

Thanks,
Gary

I am having exactly the same problem on Ubuntu 8.04 server.

I can't remember if you can do this on 8.04, but try...

dpkg-reconfigure postfix

...and select "Internet Site"

I get both of these issues too.
Does the reconfig of postfix fix that?
