All I can guess is when I moved registrars almost 2 years ago, the records that got moved were old records from the old registrar that had a track record of messing things up for me (one of the reasons for the move). My bad I did not check that what the new registrar showed is what I had running at the time. Thinking back to 4 years ago, and running sendmail I ran a full bind on that server as well. Just found my notes, that set up 7 years ago. My how the Internet has a good memory. Well 24 hours for the nameserver list to propagate. Now deal with glue records. I bet that is where the .147 addr is coming from.

What matters is not what you *think* things are set to, but what is showing to others. [also, if you didn't pull the TTL down before you made changes it really doesn't matter much what it is now.] Oh the change was made back in August in prep for a lot of changes. Still have one more to go, and it will get 'worst', as I just found out that changing ISPs is no longer just maybe a cost savings, but my current ISP is dropping their DSL service in my area in a few months. I have been with this ISP for a bit more than 7 years. I will lay odds, this TTL comes from the Registrars' glue record on this host. Which of course overrides my TTL on the zone. I am too rusty on Dig. Need to spend time with it again. Ah for the old days when you could dig out a whole zone worth of information surely - GLUE records have a *damned* long TTL because they are chicken/egg that's why you *never* should use the same A name for NS records and other things because your expectation that the TTL you think is active for the MX or CNAME you now try to changed will be wrong *and* addititionally many nameservers out there answering with old records *log* after the TTL has expired htt-consult.com. 43200 IN MX 30 z9m9z.htt-consult.com.

Take this question over the the DNS list no, you just have to read what a GLUE record is And these wonderful DNS web tools that report no glue records for NS servers not under my domain. I could not see where this is defined. And it seems not. I was again pointed where I was reading, to RFC1034. I need glue records for onlo, which I have, but not for ones like ns1.clear Further, I now see clearly that dig responses I was getting from my MiFi connection are incomplete. No additional information with those problems. Just tested again, and nope, not there. Won't bother with that again. Might as well just add the @server from regular connection to one of the root servers. But I do thank you for the help, pointing me in the right direction to check. Or rather the more right way to check DNS. Got notes on this for next time. And there will be a next time. All that readdressing to do. that's what i meant with doing your homework hours ago because you ask often the wrong questions (not only on that topic) http://en.wikipedia.org/wiki/Domain_Name_System#Circular_dependencies_and_glue_records

Please note that most, if not all mobile wireless services intercept DNS via a transparent proxy and change the responses returned to you. This is also something wired service providers are beginning to do more frequently as well. You will need a completely different means of access to DNS to get unbiased, unfiltered, trustworthy results. jd
No mail from yahoo or ymail
My new server does not seem to be allowing yahoo or ymail to deliver mail. I do not see anything in maillog, not supprisingly. My son reports he got a 'time out' bounce. I just set up a yahoo.com account for testing and a hour now and no email to me and no bounce message on my yahoo account. Any tricks with yahoo when you have oppurtunistic TLS and self-signed cert (I really hope neither of these are the issue).

The reply to that test message has not been delivered either.

It worked before the new server, so not a firewall item, as nothing changed there. As far as DNS, I changed server name in MX record. I would hope they are getting z9m9z.htt-consult.com now rather than klovia.htt-consult.com. But there is also the spf record I added for gmail: htt-consult.com.INTXTv=spf1 mx ~all And I do get emails from gmail, and can send them to gmail.

Speaking from experience, a bad netmask on a server can have surprising effects. So can a bad netmask on a router. It totally screws up routing, and one has no idea what is going until one runs a sniffer. Wietse

You said something here that triggered a thought The new server is on a different internal net than the old, thus different firewall rules. I checked over all the addressing and everything there is right, but... DCC (udp port 6277) was enabled for the old mailserver, but not the new! Could that be the problem? Well I enabled DCC and we will see as I just sent a new message from yahoo. If this does not work, I will move the new server to the old address. Really intended to do that after I turned down the old server...
