187487Host or domain name not found
- Dec 1, 2005I keep getting an error message when sending to this certain domain.
Here is the error message in the maillog:
Nov 23 17:55:01 tempe-email-01 postfix/smtp: 407686D8F0: to=<user@...>, relay=none, delay=2, status=deferred (Host or domain name not found. Name service error for name=domain.com type=MX: Host not found, try again)
but if i do: host -t mx domain.com
domain.com mail is handled by 10 domain.com.inbound10.mxlogic.net.
domain.com mail is handled by 20 domain.com.inbound20.mxlogic.net.
domain.com mail is handled by 30 domain.com.inbound30.mxlogic.net.
and if i do: nslookup -query=MX domain.com
domain.com mail exchanger = 10 domain.com.inbound10.mxlogic.net.
domain.com mail exchanger = 20 domain.com.inbound20.mxlogic.net.
domain.com mail exchanger = 30 domain.com.inbound30.mxlogic.net.
Authoritative answers can be found from:
domain.com.inbound10.mxlogic.net internet address = xxx.179.109.175
domain.com.inbound10.mxlogic.net internet address = xxx.179.109.176
domain.com.inbound10.mxlogic.net internet address = xxx.179.109.179
domain.com.inbound10.mxlogic.net internet address = xxx.179.109.181
domain.com.inbound10.mxlogic.net internet address = xxx.179.109.182
I don't quite understand how i can be getting proper dns reponses manually, but postfix can't resolve them, and it's only for this domain (that i know of) other external emails work just fine.
Also, i see the emails getting deferred, but my users never get a response that their email didn't go through. Shouldn't they get a bounce notice of some sort?
Thanks in advance for your help.
