DNS problem with Yahoo
I run a mailing list related to Hinduism at the domain
lists.advaita-vedanta.org and recently list members who use Yahoo mail
have been complaining about their posts bouncing. This is the kind of
message they get:
>--- MAILER-DAEMON@yahoo.com wrote:
> Message from yahoo.com.
> Unable to deliver message to the following
> address(es).

Now it looks like this is my problem but the user (actually an alias to
listserv) does exist and lists.advaita-vedanta.org resolves fine. Besides
people from many other sites are able to post to the list. Only Yahoo
seems to have this problem. Just in case, here are the relevant lines
from my postfix/main.cf
relay_domains = $mydestination, .advaita-vedanta.org
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_non_fqdn_recipient, reject_non_fqdn_hostname, check_relay_domains
lists.advaita-vedanta.org is a CNAME to advaita-vedanta.org. It's primary
name server is samadhi.braincells.com (216.162.42.100) which is running
woody and BIND 9. The only recent change I made to DNS was switching to
BIND from djbdns about two weeks ago.
Again this appears to be the only site which is having any problems but
it's a big one. Before I begin the arduous process of finding a clueful
human at Yahoo to talk to, can anyone spot mistakes in my setup which
could be causing this problem?
