Configuring SAP NetWeaver to send Email Externally – SAP Connect

SAP Connect has been around for quite sometime. I am sure there are plenty of documented procedures on setting it up. I recently had to configure it. I have not done this in a long time, so I figured I would capture the setup as well as point out some things to watch for.

SAP Connect can be configured for a number of different message relaying purposes. This blog post will only cover sending E-mail from SAP externally.

Some basic requirements and points:

  • SAP Connect configuration is client dependent. It has to be configured in each client where you want to use it.
  • SAP Connect requires an external SMTP server to send emails.
  • SAP Connect needs to be authorized to use the SMTP server to send emails.
  • You need to have applications configured in SAP that send external emails.

High level outline of process:

  • SMTP Server Details
  • Configuring SAP Connect INT Node
  • Configuring Routes For SAP Connect INT Node
  • Configuring SAP Connect Default Domain
  • Scheduling Send Process
  • Setting Up Your User ID with and External Email Address
  • Testing Your Configuration
  • Monitoring SAP Connect

SMTP Server Details

Let’s start with the most important piece of the puzzle. If you don’t get this part right, your configuration will not work. You need an external SMTP server to relay your outbound email messages. Most companies running SAP will have at least one SMTP server. It is also possible you might have several to choose from. So, you need to identify the appropriate SMTP server.

You will need to know the SMTP server Host Name as well as the Port. The default Port for SMTP is 25, but your administrator has the option to change this. Make sure you confirm the correct port number.

Identifying your SMTP server is the first piece of the puzzle. The next piece is to request permission to use it. Most corporate SMTP servers are protected–they only allow trusted servers / authenticated users to use them. You will most likely need to contact your email system’s administrator to request authorization for your SAP servers. If you will be using SAP Connect in your Development, Test, and Production environments, it is a good idea to request all of them at once. NOTE: If you physically move your SAP server to new hardware in the future or change your servers IP address this authorization will most likely break.

The reason your corporate SMTP server is typically protected is to avoid internal / corporate spammers–both intentional and unintentional.

Configuring SAP Connect INT Node

Now that we have an SMTP server to talk to, we need to configure SAP Connect. The transaction in SAP is SCOT. Remember, SAP Connect is client dependent so you will need to repeat this procedure in all clients that require the ability to send email externally.

SAP Transaction SCOT

When you execute SCOT you should see a similar screen.


You will need to select the INT entry, and from the “View” menu, select “Node”.

Select the INT entry again and click the create paper 200908151751.jpg on the tool bar.


  1. Fill out the Description field as desired.
  2. Set the “Node in use” flag.
  3. Fill out the Mail Host (Host Name or IP Address) – Host Name is recommended.
  4. Fill out the Mail Port (Default 25)
  5. The default Code Page will work for many implementations.
  6. Next, click the SET button next to Internet in the Supported address types

The following screen should appear:


Here we configure allowed routes for external emails. In this example we have configured a “*” which will allow any email address domain to be routed. It is also possible to only allow specific routes, like or

If your system manages HR data or patient data, it is a good idea to check with your compliance office to ensure external email policies are being adhered to in productive systems.

Additionally, you may also want to restrict certain routes in Test and Dev systems so your testing does not generate emails to external business partners.

After you click the green check your screen will look as follows.


Configuring SAP Connect Default Domain

Now you need to configure a default domain for the server. From the settings menu select Default Domain.


Add your company domain name.


Scheduling Send Process

Messages are not relayed synchronously. They are relayed asynchronously via a scheduled background job. You must schedule this job for your messages to be relayed.

On the menu bar click the execute button 200908260901.jpg .

The following screen will pop up.


Now click the the create button pulldown 200908260903.jpg, and select “Schedule Job for INT”.



Name your job. Remember, SAP Connect is client dependent so if you are in a multi client development or test system it is a good idea to include the client number in the name.

It will default address type to INT Internet Mail Address.

If you have a high volume of messages you will want to up the number of work processes as well as consider using a server group if you have them configured.

You will want to schedule with job with a system ID or background ID. In this case we are using BATCH-ID.


Click Continue.

The following screen allows you to customize the setup of the background job. I have schedule this job to run every ten minutes on the two minute of the hour (e.g. xx:02, xx:12, xx:22, xx:32, xx:42, xx:52).


To adjust the period select 200908260913.jpg


In this case we are picking a period more frequent than Hourly so select 200908260914.jpg


Fill in the period that meets your requirement. Hit save 200908260916.jpg (you will need to do this several times to get to the next screen).


Hit save 200908260916.jpg one more time and it should return you to this screen.


You can  review and make changes to your job with the SAP transaction SM36.

Setting Up Your User ID with and External Email Address

If you want SAP users to receive email notifications from SAP applications, you will need to make sure that their email address is correctly maintained on their user account in SAP Transaction SU01.

Please confirm that E-Mail is maintained for users in the Communication Section.

Testing Your Configuration

You can test your configuration using the SAP Business Workplace. The SAP Transaction to access your mailbox is SBWP.


Click the New Message Button 200908151825.jpg .

Create a test message.


To test, you need to select an external email address for the Recipient. Make sure the domain is allowed in the route you setup in the prior step. In this example, any external email address should work.

You can review the status of your message by viewing your outbox.



Your message will be sent at the next execution of the mail-send job we just configured.

You can check the status to the send job with SAP transaction SM36.


Once the send program has executed, check the email inbox for the message recipient. You should see your test email.

Monitoring SAP Connect

To monitor you can use the SAP transaction SOST.

Here you will see all outbound messages and their current send status. You can also process the messages from the menu.

    We have followed your document to setup in system. It seemed that we could send the internal address fine.
    However, we could not send the external email address. We checked the setting with your document. We could not find out the problem.

    Please advise where is missing or need to maintain to allow send R/3 email to external email address.

    The first place I would look is with your route configuration. Did you use a wild card * for your route? The route is one of the first few steps that I describe. If yes then I would contact the admin team in charge of your SMTP server. See if they are blocking you on the STMP server from sending externally. It should be one of those two issues. You are getting internal emails so that confirms that most of your configuration is correct.

    What are you seeing in SOST for the message that is not being sent correctly?

    Hi Levi, you can but you need to add the address in SCOT under that smtp node for internet. eg: I would suggest you don’t put * etc as this could be a breach of your security rules etc.

    Hi Tim/All

    I am trying to define emails to external users though a centralised no-reply email address. So I have have only been able to send emails only via an individuals email address and not though a predefined group email account. Hope you understand this. Please see below example.

    My address
    Rec address
    Email to be sent

    Thanks in advance
