Folks,

Our ASP application has been sending emails using SMTP server for almost
2-3 years now. All of a sudden we keep receiving these random
undelveriables, which doesn't make sense since this email address
exists, from our previous experince.

An example:
====
Your message did not reach some or all of the intended recipients.

Subject:	<subject matter>
Sent:	4/19/2005 4:22 PM

The following recipient(s) could not be reached:
joe@test.com on 4/19/2005 4:22 PM
You do not have permission to send to this recipient.  For
assistance, contact your system administrator.
<server_name> #5.7.1 smtp;550 5.7.1 Unable to relay for
joe@test.com>
====

Changed the server name, email address only, but you get the basic
picture.

We have also enabled smart host on server that has SMTP installed.
Our SMPT server is W2K and Exchange server is Windows 2003.

Any help is much appreciated.

Thanks.

I just fixed this on mine which was doing the very same thing. Unintstalling
Norton fixed it believe it or not.

You are right, I don't quite believe this.

But thanks for your input and time.

Microsoft on a tech support call has confirmed that on access anti virus
scanning products can create problems between IIS SMTP and Exchange.

For whatever reason they choose not to post this in any KB articles.

The problems will be intermittent or can start up out of the blue.  AV
tools get updated, not only the dat files but the engine itself get
updated, hence it is possible for thing to work one day and not the next.
