i have same issue my mx record id mydomain.com

i am facing same issue ... i have created my mx as shown below

mydomaini.com MX preference = 10, mail exchanger = hit-hts.notsameasmydomainname.com

hits-hts.notsameasmydomainname.com internet address = 10.10.10.10

please detail how do i fine tune my mx entry...

do i need to keep the same name for the mail exchanger also
for eg:- mydomain.com mx pref= 10 mail exchanger = mail.mydomain.com

is this correct way

Chris Dent

Absolutely nothing wrong with what you have there as long as hit-hts is accepting mail for your domain.

What are you seeing that's causing a problem?

one of my user getting NDR while sending to one particular domain

mx3-oak.GreenKey.net #554 5.7.1 Service unavailable; Sender address [user@mydomain.com] blocked using bogusmx.rfc-ignorant.org; Domain has demonstrably bogus MX records ##

to some domain i get

#530 5.7.1 Client was not authenticated ##

for another one

management@french_fashion_university.com
#554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain ##

how to resolve these issues...

i am facing sending problems with only 3 or 4 domains...

Is that inbound or outbound?
Do ensure that you do not have 10.x.x.x IP addresses in your DNS settings that are seen from the internet, as that will get you blacklisted.

The last error could be with your SMTP banner being invalid. As you haven't said which version of Exchange, further advice is impossible on correcting that.

internet address = 10.10.10.10

if this is true - then this is your problem 10.* is a private address space and shold be replaced by you external ip address

my real ip is different not 10.10.10.10.

i have issue for outgoing mails.i am using exchange 2007

This is the system they're using to block you:

http://www.rfc-ignorant.org/policy-bogusmx.php

We need to figure out exactly what in your MX record is causing that flag. I don't suppose you can tell us the real domain can you?

Otherwise, I'd say the most likely is that the name your MX points to is a CNAME. Could you run:

nslookup hits-hts.notsameasmydomainname.com

And tell us if it lists "Aliases" in the response you get?

This one:

> french_fashion_university.com

Will never work, you won't find public domains using underscore characters like that. Their usage is not RFC compliant. That would be a case of check the recipient address and try again after correcting it. Basically, not your problem and entirely unrelated to this issue.

Ahh good, that's a relief, not sure why it didn't do that in the first place. Ah well. Any luck getting mail through to that recipient now?
