e-mail bounce backs

We are trying to sending e-mail to countrywide.com.  We are able to receive e-mail from them with not problem.  When trying to reply or start a new e-mail we get a NDR stating the following.

user@Countrywide.com on 11/6/2008 10:28 AM
            You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            < sfdmzmailmx01.bankofamerica.com #5.7.1 SMTP; 550 5.7.1 Unknown user: user@Countrywide.com>

The part that has me stumped is that it is coming form bank of america??  

All other domains and e-mail is working fine.

Any and all help is apprecaited.

Hi

Please see the attached snippet.  It would appear countrywide.com's DNS MX records are set incorrectly to the bankofamerica.com's servers.

Either this is an error on the part of who ever manages countrywide's DNS system or CountryWide is part of Bank of America but the e-mail servers haven't been told!!!
nslookup
Default Server:  ukmikwh-dc1
Address:  10.243.25.105
 
> set q=mx
> countrywide.com
Server:  ukmikwh-dc1
Address:  10.243.25.105
 
Non-authoritative answer:
countrywide.com MX preference = 10, mail exchanger = vaemail2.bankofamerica.com
countrywide.com MX preference = 10, mail exchanger = sfemail2.bankofamerica.com
countrywide.com MX preference = 10, mail exchanger = txemail2.bankofamerica.com
 
vaemail2.bankofamerica.com      internet address = 171.159.193.178
sfemail2.bankofamerica.com      internet address = 171.159.65.178
txemail2.bankofamerica.com      internet address = 171.161.161.178

I did the same thing and got the same results.  Countrywide said they have been getting mail from other domains throughout the day so not sure why we can not.  I agree with what you are saying but I guess why us?

Perhaps a DNS fix is still replicating?  It could be that the DNS information I saw when I checked and that you have seen is cached - usually solved within a day.

I have made a direct connection via telnet on port 25 and sent a test message to postmaster@countrywide.com, the bankofamerica.com mail server seemed to accept the message.  See attached

can you please give me step by step on how to send a test messgae so I can try from my domain please?  

0
 
SCarrisonCommented:
Start > Run > CMD > OK
telnet <bankofamericamailserver> 25 [enter]

You should see a telnet window open with an SMTP banner across the top

helo <yourmaildomain>.com
mail from:<validmailaddressatyourdomain>.com
rcpt to:<validrecepient>.com
data [enter]
test mail please reply
. [full stop on a line by itself]

you should then see "mail accepted for delivery"

If you do not, I expect their mail server doesn't like your domain... perhaps spam blacklisted?

Bank of America recently acquired CountryWide.. I dont think that is a problem.  (http://www.npr.org/templates/story/story.php?storyId=18028482)

You are getting 550 5.7.1 Unknown user: user@Countrywide.com - is that the correct email address?

that's a pretty standard and perfectly OK mail acceptance, however, it doesn't look like the bank of america server I tried

try your telnet on port 25 to vaemail2.bankofamerica.com

tpgrpitCommented:
Did this ever get solved?  We are experiencing the same issue.  We use postini for inbound scanning but send out normally through our exchange server.

My theory is...I think it might have to do with how some people check for legit senders.  If you are using postini and set your smtp server to only accept connections from postini and the banner on the smtp for your mx does not match.  

I dunno, I have seen it once before with an old backup mx spooling service we used.  I'm still trying to fix this one though.

dplawAuthor Commented:
I get them on occasion, but no still have not completely resolved.  I did notice that in the smtp virtual server delivery properties they use the name of the exchange server, followed by domain instead of mail.domain.com which the mx record has.  I plan to fix that when going to exchange 2007.  Wich I could help out more, sorry.
