  ;; ADDITIONAL SECTION:

Your first MX host sometimes resolves to 208.83.67.147, which
doesn't appear to be reachable on port 25. When this resolves to
.180 it is.

Your second MX host rigel.htt-consult.com resolves to 208.83.67.188,
which doesn't appear to be reachable on port 25

Additionally, given the TTL shown on the z9m9z.htt-consult.com.
A-record, did you bring your TTLs down before you made what I assume
was an MX host IPnumber switch? If not, and that 2-day TTL is
indicative of what you generally use, it could be a bit before the
nameservers that various mail servers use will need to requery (and
if they get the .147 address it likely won't do them any good
anyway).

To debug this type of thing you need to look at what the outside

fake pre-MX records, becuase they did not seem to help too much and just

It was a registrar problem.  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.

You may not have been pointing z9m9z at .147 for years, but
there's a nameserver that is showing that. Also you may have the TTL
at 2 hours on the SOA that you are working with, but there's a
nameserver that's returning answers that is showing 2 days:

   ;; ADDITIONAL SECTION:
   z9m9z.htt-consult.com.   172799  IN  A   208.83.67.147

just do the math. 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.]

Postfix logs all connection attempts, so they are not coming
through some firewall, or they aren't getting your DNS
information.

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.

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

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...


I'm seeing a couple of things when I look at your DNS records:

   dig htt-consult.com mx


;; ANSWER SECTION:
htt-consult.com.43200   IN  MX  30 z9m9z.htt-consult.com.
htt-consult.com.43200   IN  MX  40 rigel.htt-consult.com.

;; ADDITIONAL SECTION:
z9m9z.htt-consult.com.  172799  IN  A   208.83.67.147


Your first MX host sometimes resolves to 208.83.67.147, which
doesn't appear to be reachable on port 25. When this resolves to
.180 it is.

Probably 4+ years ago a z9m9z was at .147; for the past 3 years
hp7310 has been using that address!


Your second MX host rigel.htt-consult.com resolves to
208.83.67.188, which doesn't appear to be reachable on port 25

That is to handle spammers that go to the last MX record, assuming
that is the real server.  It actually stopped 15% of spam coming
into my old server.  It is part of the 'nolisting'
recommendations. I dropped the 2 fake pre-MX records, becuase they
did not seem to help too much and just added delay, while the last
bad one did not seem to be causing problems.  I am pretty sure I
have received yahoo mail with it in place.  I can remove it if
makes a difference..


Additionally, given the TTL shown on the z9m9z.htt-consult.com.
A-record, did you bring your TTLs down before you made what I
assume was an MX host IPnumber switch? If not, and that 2-day TTL
is indicative of what you generally use, it could be a bit before
the nameservers that various mail servers use will need to
requery (and if they get the .147 address it likely won't do them
any good anyway).

2 days???  This is the SOA I have been using during these changes:

htt-consult.com.IN  SOA onlo.htt-consult.com.
rgm.htt-consult.com. (
  2014120201
  2H
  20M
  2W
  2H )

I read this as 2Hours TTL.


To debug this type of thing you need to look at what the outside
world is seeing. Query the DNS so that you see results as seen
from the outside, and then try to telnet (from the outside) to the
resulting ipnumbers.

As I have done.  I use MiFi on my phone and connect another
notebook to it to look 'in' and did not see this bad IP address
that somehow is long since hung around.

Got a hunch on that


You may not have been pointing z9m9z at .147 for years, but
there's a nameserver that is showing that. Also you may have the TTL
at 2 hours on the SOA that you are working with, but there's a
nameserver that's returning answers that is showing 2 days:

;; ADDITIONAL SECTION:
z9m9z.htt-consult.com.  172799  IN  A   208.83.67.147

just do the math. 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

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.

And these wonderful DNS web tools that report no glue records for NS

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

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

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

No mail from yahoo or ymail

2014-12-04 Thread Robert Moskowitz

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).

Speaking from experience, a bad netmask on a server can have
