By late afternoon emails to Comcast.net started going out . The only change was installing pdns-recursor earlier in the day . Does pdns-recursor take awhile to start working ?
Much thanks for everyone's help.

Bind returns very close to 512 bytes, while pdns is just under 100 bytes. This is true when using "-t MX" as well (which is what I expect qmail is doing). Replies from pdns are *much* smaller, so it appears that pdns is running ok. I'm not seeing any cname records. Can you poke around and see what might be causing a cname lookup of some sort? -- -Eric 'shubes' On 12/13/2012 09:46 AM, [email protected] wrote: > This is what I get when I dig comcast.net > > [root@mail1 pdns-recursor]# dig comcast.net > > ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.5 <<>> comcast.net > ;; global options: printcmd > ;; Got answer: > ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 15929 > ;; flags: qr rd ra; QUERY: 1, ANSWER: 4, AUTHORITY: 0, ADDITIONAL: 0 > > ;; QUESTION SECTION: > ;comcast.net.
