>Description:
Since saturday august 31th 2002, 13:45 EST (UTC+10) I'm not able to send
any more mail to and haven't received any more mail FreeBSD.org domains.
After some searching I found out that mx1.freebsd.org refuses all mail
from domains hosted on secondary.com:
Host topaz.mdcc.cx: mail from @mavetju.org:
host mx1.freebsd.org[216.136.204.125] said: 450 <edwin@mavetju.org>: Sender
address rejected: Domain not found)
Host bps.jodocus.org.
450 <bps.jodocus.org>: Helo command rejected: Host not found
Host mud.fataldimensions.org.
450 <mud.fataldimensions.org>: Helo command rejected: Host not found
These are three different machines all over the world with one thing in
common: their DNS services are provided by secondary.com.
This can be because of a couple of things:
- mx1.freebsd.org doesn't know where ns1/ns2.secondary.com are.
- ns1/ns2.secondary.com don't know where mx1.freebsd.org is.
- somebody is blocking IP traffic somewhere between freebsd.org and
secondary.com
- ns1/ns2.secondary.com are blocking DNS requests coming from mx1.freebsd.org
Which one? I don't know.
I had earlier today send an email to postmaster/hostmaster@freebsd.org
and got an answer from Peter Wemm, who gave me this information:

>How-To-Repeat:
On mx1.freebsd.org, "dig mavetju.org. ns @198.133.199.3 +vc"
>Fix:
Right now this PR is only to keep track of the problem, I've filed a PR with secondary.com too and am waiting for their answers.
