error 4.4.7 exchange 2000

[technical]

Hi All,

Been having this prob fro a while now, I made a script that sends out our company price list to every purchaser in our database, however all the messages are returned as a 4.4.7 error, here's an example :

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

Subject: MRi Pricelist
Sent: 02/10/2007 13:17

The following recipient(s) could not be reached:

username @ domain.tld on 04/10/2007 09:32
Could not deliver the message in the time limit specified. Please retry or contact your administrator.
<mri.co.uk #4.4.7>

Now each email is made separately, so there is not a long list of recipients in the header. The header info looks a bit like this :

From: $email
Reply-To: $email
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="$sep";

Content-Transfer-Encoding: 7bit
this text should not be seen.

--$sep

Content-Type: multipart/alternative; boundary="$revSep"
Content-Transfer-Encoding: 7bit
--$revSep

Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 8bit

etc. etc. I think u get the picture. I don't think there is anything wrong with that as sometimes (not very often) they do get through.

We host our own SMTP Server in our exchange server, which forwards mail to our ISP e-mail host, which should pass the messages on to the recipients so that reverse dns lookup sees them as I think ours is probably bad, not too sure. Any suggestions of how to find out where are e-mails are not getting to?

Thanks

A 4 something error indicates the message is deferred, not rejected. If you never get a 5 something error, just don't sweat it.

[technical]

But this is a continuing problem. The e-mail is being treated as undeliverable. We are trying to send this e-mail out to about 500 customers, and pretty much all of them are coming back with the same error message. Is there a way to find out if it's going through our ISP or being rejected by them or each customer.

Thanks for your time

Except 4xx is not undeliverable. It's deferred.

Post the full test of the error message and we can probaby figure it out.

Put it in a private message to me if you aren't comfortable posting ig.

I was looking for the header too.

[technical]

How do I retrieve that using Outlook 2000.

However if you have a look at my first post you can see how the header is made.

When saving the e-mail and having a look at the header, it shows the same info as expected. Although it's from postmaster / system administrator.

[Scott Kitterman]

The trick is figuring out if it's your ISP mail server or the one on the distant end that is generating the message.

If you are attempting to send all 500 in a short time interval, then your ISP might have a throttling feature which gives such a response. As Scott said, without the full header we can't tell where the response came from. But if you are sending to many different domains, then my guess is that the message is due to exceeding the short-term (usually one hour) sending limit of your ISP.

How do I extract the header info using Outlook 2000?

I receive the same problem if I just send one message also.

Is there a way to track an e-mail sent to see where it gets returned from?

The full headers should be visible when you use the View>Options selection while viewing a message.

These full headers contain the information on which servers handled that particular email.

Thanks, sorry, here they are :

Thanks for all your time

The error response was sent from your mri.co.uk server, due to problems delivering to the hotmail address after over 4 hours.

I don't understand these comments you made:
"We host our own SMTP Server in our exchange server, which forwards mail to our ISP e-mail host, which should pass the messages on to the recipients"

Although the error message doesn't tell us much about the source of the delay, it appears likely to me that the message isn't getting from your SMTP server through your ISP. Your ISP may be blocking this transaction, which might be some kind of relaying.

Does your system work correctly for manually generated emails? If so, then your automation is somehow not logging into your ISP correctly. Are you using authentication with your ISP?

Bill

[technical]

Yes, I think you've hit the nail on the head.
Our normal mail goes through just fine. We have an Exchange Server that is set up to relay mail to our ISP via SMTP. The application that sends the automated messages, offers authentication when sending, but when using that function returns the error that our SMTP Server does not require authentication but the ISP one does. Is there a way to set up our Exchange 2000 SMTP server to either require this authentication or to send it out pre authenticated to our ISP, in a secure manner so that spam engines can't use our server to relay.

Thanks

Sorry, I have no idea about configuration of Exchange 2000. Maybe someone else can respond.
