  • 4. Plan - migrating SBS 2003 to new hardware
    Hey there, I will be migrating our existing SBS2003 to a new box. And here's how i plan to do it and was wondering if it will work. Here are the steps: 1) Move all existing mailboxes to pst files with exmerge. 2) Manually create all users since we do not have that many users. 3) The new SBS box will still use the same static ip as the old one and also the same name. 4) once the new SBS 2003 installation is done plug it back to the network and remove the old SBS 2003 box. I was wondering if that will work. Or will all the other computers other servers have any problems working. Thanks Eric

5.5.0 smtp;550 Authentication required

Postby cmplbms » Thu, 31 Aug 2006 14:14:02 GMT

Recently we have began having a rash of mail bounces with the following 
information presented:

There was a SMTP communication problem with the recipient's email server.  
Please contact your system administrator.

<ourcompanyname.com #5.5.0 smtp;550 Authentication required.

This server has been operating without problems for over a year.  The domain 
is not blacklisted and I have verified configurations using 
www.dnsreport.com.  Exchange is configured to use DNS for sending mail.  Is 
this the issue?  We use business class Road Runner.  Should I be forwarding 
mail to them instead of using DNS?  

To my knowledge, the server is patched with all of the latest patches and 
all systems use Symantec Antivirus Corp.

I have done a great deal of searching but cannot find a concise answer.

Any help would be appreciated.

i,

Thank you for posting here.

According your description, I understand you encountered 550 NDR when
sending emails?

In order to get a clear picture on this issue, please let me know the
following questions:
Does the issue occur on certain users or all users?

Does this issue occur when you sending to internal recipients? Or external
recipients?

Does this issue occur when you send to all external domains or just some
specific domains?

I would like to suggest you perform the following steps to narrow down this
issue.


Step 1:
=====================

1. On the Windows taskbar click the Start button, point to Programs, point
to Microsoft Exchange, and then click System Manager

2. In System Manager dialog box, expand the Servers container, expand the
Protocols container, and then expand the SMTP container.

3. Right click Default SMTP Virtual Server, and in the Properties dialog
box, click the Access tab.

4. In the Access dialog box, under Access control, click the Authentication
button.

5. Under Select acceptable authentication method for this resource, click
to select the Anonymous Access checkbox, and then click OK.
NOTE: This setting allows any user to send mail from this Exchange server
computer.

Step 2: Check the PTR record
=====================

Verify the PTR records for the Exchange SMTP domain from the following
website: http://www.dnsstuff.com/

Step 3: Using Telnet
===============
Try to telnet to the remote mailer directly to test the issue. Detailed
steps are documented in the following article:

153119 XFOR: Telnet to Port 25 to Test SMTP Communication
http://support.microsoft.com/?id=153119

Step 3: Bypassing DNS
==================
Configure the SMTP connector to deliver message directly to the remote mail
server without DNS. To do so, see the following article:

285863 How to Bypass DNS Name Resolution to Test SMTP Mail Flow to Remote
http://support.microsoft.com/?id=285863

In addition, please collect the following information to me so that I can
find more information about the issue.


1 Collect the Message Tracking info to me.

a) Enable Message Tracking on. For more information, please refer to
the following KB article.

257265 XCON: General Troubleshooting for Exchange 2000 Transport
Issues
http://support.microsoft.com/?id=257265
b) Please send a message to reproduce the issue.
c) Search for the message in Message Tracking centre.
d) Double click to open it, make a screenshot of Message Tracking center
and send it to me as well.

3. Use the WinRoute tool below to collect the routing information to me.

http://www.microsoft.com/downloads/details.aspx?familyid=c5a8afbf-a4da-45e0-
adea-6d44eb6c257b&displaylang=en

4. Configure diagnostic logging on the Exchange 2003 server.

1) Start Exchange System Manager.

2) Expand "Administrative Groups", expand "First Administrative Group",
and then expand "Server".

3) Right-click the Exchange Server that is listed under "Servers", and
then click "Properties".

4) Click the "Diagnostics Logging" tab, and then click to select the
"MSExchangeTransport" box under the "Services" box.

5) Set the "Logging level" of each Category to "Maximum".

6) Click "OK".

After you reproduce the issue, send the Event Viewer logs to me.

Step 1: Click Start, click Run, and then type "eventvwr" (without the
quotation
marks), cli

You may be being redirected to a RoadRunner mail server automatically - 
and then blocked because it requires authentication.

I'd speak to them to find out if they are blocking outbound SMTP. It's not 
an uncommon thing for ISPs to start doing unannounced.

1.#5.1.0 smtp;550 5.1.0 Authentication required

I'm a novice MCSE. On the side I'm supporting a small network (SBS - 3 
workstations - Exchange).  The small network was built nicely by a networking 
company who became too expensive for my client, who is a friend, who asked me 
to support it.

The first Thing (and only thing) I've done was changed the Administrator 
Password on the server.

Now I've had reports of this error when users try to reply to emails.

 The e-mail address could not be found. Perhaps the recipient moved to a 
different e-mail organization, or there was a mistake in the address. Check 
the address and try again.
  <mydomain.com #5.1.0 smtp;550 5.1.0 Authentication required



They can email successfully if they type out the email address, but it will 
not work when they simply hit reply and send.

Does anyone know what I can try to do to fix this?

Thanks

As noted earlier, this just came out of the blue. No settings were
changed that I know of. I can't send anything, but mail is received
just fine.
     Has anyone had this happen and do you know of a cure?
Mozilla Thunderbird has no problems sending.
     Help much appreciated.

4.SMTP communication problem smtp;550 - emails bouncing back

Recently my customer has had emails bouncing back with the error:
There was a SMTP communication problem with the recipient's email server. 
Please contact your system administrator.
<Customer.com #5.5.0 smtp;550-(Customer.com) [1.2.3.4] is currently not 
permitted to relay through>

I do not have a MX record pointing at the Exchange server on the SBS2003R2.
I do not have a smart host setup at this time.
We do have a static IP on the router for the outside and I do have access to 
our dns records at our host.
What would be the proper way to deal with this issue?
Should I do something with MX record and dns?  If so how?
or
Should I setup a smart host to relay from the ISP (Verizon)?

Below is information about our system and information from some of the 
bounced emails.   Names and IP's were changed to protect the innocent.
Any help or advice would be appreciated.
