cyberlei -> 550 4.4.7 QUEUE.Expired; message expired ## (11.Jun.2009 8:54:35 PM)

Hi all,

I have a in house exchange server 2007 and face an error when sending email to one particular domain, however we can receiving the email from that particular domain. 

I checked SMTP diagnostic, MX lookup and blcaklists on our and their domain name. did not see any errors and both domain have REV DNS (PTR) record. Also able to telnet 25 on both exchange server.

most likely the issue on our end.

Here is the error message:

#550 4.4.7 QUEUE.Expired; message expired ##

any idea deeply appreciated

Thanks,
Cyberlei

Cyberlie,

Did you check the helo/ehlo which is send when connecting to the other mailserver ?

Can you post the piece of SMTP logging ?

Hi,

Please enable smtp logging:

- open the EMC
- select the HUB server
- select the send connector
- set the logging level to verbose

Reproduce the issues and set the logging level back to the original level and post the log here.



cyberlei -> RE: 550 4.4.7 QUEUE.Expired; message expired ## (16.Jun.2009 6:42:25 PM)

Hi Jveldh,

I switched the logging level to verbose from None.
here is the smtp logging

jveldh -> RE: 550 4.4.7 QUEUE.Expired; message expired ## (17.Jun.2009 2:20:35 PM)

Hi,

It looks like it some kind of DNS configuration issue on your side:

Recipient address rejected: Valid DNS required on connecting IP

Can you send me a private message with your domainname ? Then I can check somethings.



cyberlei -> RE: 550 4.4.7 QUEUE.Expired; message expired ## (17.Jun.2009 3:13:26 PM)

Hi Jveldh,

PM has been sent to you

Thanks again
Cyberlei



jveldh -> RE: 550 4.4.7 QUEUE.Expired; message expired ## (17.Jun.2009 4:59:14 PM)

Hi,

I've checked you settings but it looks like their is something strange with your PTR record. Some DNS servers give a good reply while others are not.

Did you changed it a few hours ago ?

If so please wait 48 hours and try again to send mail to the specified domain.



cyberlei -> RE: 550 4.4.7 QUEUE.Expired; message expired ## (17.Jun.2009 5:21:05 PM)

no, I did not change anything on my end yet, I was talking to their domain admin and working with them for resolving the issue

PS: Can I PM you for one PTR record question

Thanks
Cyberlei



cyberlei -> RE: 550 4.4.7 QUEUE.Expired; message expired ## (22.Jun.2009 2:53:29 PM)

Hi All,

The issue has been resolved by contact ISP to create PTR record pointing your WAN IP address If you don't know your WAN IP address, simply go to www.whatismyip.com

Thanks,
Cyberlei
