Emails bouncing (wrong domain name in some setting)

Hi Guys,

Here is the problem, emals are bouncing back with the following error message.

From: System Administrator
Sent: Wednesday, November 29, 2006 9:35 AM
To: j.santopetro@dsarchitects.com
Subject: Undeliverable: i4Vision - Report on your Website

Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:

j.santopetro@dsarchitects.com on 11/29/2006 9:31 AM
The message cannot be delivered due to a configuration error on the server. Please contact your Administrator.
<4vision.com #5.3.0 smtp;553 5.3.0 ... denied>

we are running a microsoft exchange version 6.5.7638.1 on a windows server 2003, we have reverse lookup properly configurated in our DNS.
the problem is, that as you can see the error message says <4vision.com ....> and our domian name is i4vision.com, there is a letter missing on it.
will that be the problem?
i'll appreciate if you guys can take a look to this problem and give us some information...
if you need further information please let me know.!!
Regards,
Marcelo.

Well for one thing you do not have a reverse DNS record in your PUBLIC DNS records.

The RDNS should be configured for you by your ISP.

You stated:
"we have reverse lookup properly configurated in our DNS."
This will not help if the receiving domains do a reverse DNS lookup unless your DNS is visible from the public world.

ran a check on the i4vision.com name at www.dnsstuff.com using the DNS report tool. There were a few errors. Please check it out and correct.

Recheck your reverse DNS entries at your site and at the ISP's site as well as correcting the SPF records. Check afterwards.

Just in case I also sent that address an email and it failed to deliver.

Hi. This is the qmail-send program at yahoo.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<j.santopetro@dsarchitects.com>:
121.73.26.199 does not like recipient.
Remote host said: 553 5.3.0 <j.santopetro@dsarchitects.com>... denied
Giving up on 121.73.26.199.


Can you check with them as to the status?
