SBC's SMTP server quit working with SMTP connector

SBC's SMTP server quit working with SMTP connector

Post by RXJpY » Wed, 03 Aug 2005 23:16:04


Anyone using SBC for DSL services knows that in order to use their SMTP
server with SBS 2003's SMTP connector you must use the following address:

[66.163.171.137]

Well, two of my clients that use SBS are unable to send mail now, and the
SMTP queues have grown substantially. Does anyone know of any changes in the
behavior with SBC's SMTP server in regards to setting it up with the SMTP
connector? I'd call SBC, but I figured I would get an accurate answer faster
in this newsgroup.

Thanks.

ello Eric,

Thank you for posting in the SBS newsgroup.

According to your description, I understand that two of your clients cannot
send outbound emails, and you have some questions with SmallBusiness SMTP
Connector and Default SMTP Virtual Server. If I have misunderstood your
concern, please don't hesitate to let me know.

To troubleshoot this issue that two of your clients cannot send outbound
emails, I would like you to be familiar with CEICW (Configure Email and
Internet Connection Wizard) first. This wizard is specially designed for
SBS and helps you configure the internet access, firewall and email
settings of the server. More information:

825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763

For the email part, let me explain it to you in detail:

a. Run the CEICW and go through the Internet and firewall option.

b. In the Internet E-mail tab, please click to "Enable Internet
E-mail".

c. In the Email Delivery method page, please choose the correct
email delivery method. If you need to forward internet email to your ISP
Smarthost, please input the Smarthost address correctly. If you use DNS to
route emails, please choose this option.

Note: If you choose to forward emails to the ISP's email server (smart
host), you need to type the FQDN of the ISP's email server. If your ISP
provides you the IP address of their email server, for example,
12.34.56.78, you should type the IP address as "[12.34.56.78]" (without the
quotation marks) on the connector's properties page.

d. Input the correct information in the rest page and finish the
wizard. Note: you could just leave the option unchanged, since your
Exchange could receive internet emails fine.

For delivering the internet emails, if you have hardware router, you should
make sure the Outbound TCP port 25 is opening. For your ISP configuration,
you ISP should allow TCP port 25 outbound communication.

If your SBS server uses ISP smarthost, I would like to bring the following
article to your attention

827601 Cannot send external mail when your smart host server is different
from
http://support.microsoft.com/?id=827601


In addition, for your question: Does anyone know of any changes in the
behavior with SBC's SMTP server in regards to setting it up with the SMTP
connector?

Answer: In SBS 2003, the CEICW automatically creates a SMTP connector for
outgoing messages. The bridgehead defines the Exchange server which can use
this SMTP connector to deliver the outgoing e-mails.

SMTP connector is based on SMTP virtual server and SMTP service. It
provides more functions than the SMTP VS does. You may use SMTP connector
in the following scenarios:

* You are connecting to a Microsoft Exchange Server 5.5 computer in another
routing group (site), and want to use SMTP.
* You want to configure either server-side or client-side ETRN/TURN.
* You want either to send or not to send ETRN/TURN.
* You want to request ETRN/TURN when sending messages.
* You want to request ETRN/TURN from different servers.
* You want to configure outbound security, and to do it one time and affect
many outbound servers.
* You want to permit high, normal, or low message priorities for a domain.
* You want to permit system or non-system messages.
* You want to schedule the SMTP connector.
* You want to use different deli

think you misunderstood the problem. Nothing is wrong with the
configuration of the SBS 2003 servers, and my concern does not pertain to the
SMTP connector and default SMTP virtual server. The problem is that I am no
longer able to send emails via SBC's SMTP server. However, I switched the
SMTP connector to use my SMTP server to make sure everything is functioning
okay, and the servers are both able to send mail now. However, I'd like to
get them back on to SBC's SMTP. Is anyone aware of any changes to SBC's SMTP
servers?

i Eric,

Thank you for your kind reply.

I am sorry for my misunderstanding on the problem.

As you mentioned, you can send emails via SBS SMTP Connector, but you
cannot send emails via SBC's SMTP Server. If you would like to change to
send emails via SBC's SMTP Server, please follow the below steps:

1. Please contact the SBC to confirm the name or IP address of their mail
server to forward to.

2. Run the CEICW and go through the Internet and firewall option.

3. In the Internet E-mail tab, please click to "Enable Internet E-mail"

4. In the Email Delivery method page, choose forward internet email to
your ISP Smarthost, and input the Smarthost address correctly.

Note: You need to type the FQDN of the ISP's email server. If your ISP
provides you the IP address of their email server, for example,
12.34.56.78, you should type the IP address as "[12.34.56.78]" (without the
quotation marks) on the connector's properties page.

5. Input the correct information in the rest page and finish the wizard.

6. Based on my research, the SBC need to configure authentication using
SBC ID and password. After rerunning the CEICW, please follow the steps
below to configure outbound security:

A. Open Exchange System Manager.
B. Expand Connectors, right-click SmallBusiness SMTP connector and click
Properties.
C. On the Advanced tab, click Outbound Security.
D. Select "Basic authentication (password is sent in clear text)" and click
Modify to enter user name & password.

Additionally, for delivering the internet emails, if you have hardware
router, you should make sure the Outbound TCP port 25 is opening. For your
ISP configuration, you ISP should allow TCP port 25 outbound communication.

I am appreciated your time and cooperation. If anything is unclear, please
feel free to let me know. I am looking forward to hearing from you.

Best regards,

hank you for your suggestions. I had everything working fine with SBC's
smtp servers, authentication and all. They just stopped working for no
apparant reason, and I'm surprised no one else has experienced this same
problem. I will call SBC first thing Monday.
