SAP ECC permits sending and receiving of messages, including email. NetWeaver ABAP comes with everything needed to set up the configuration. What is needed is an external email infrastructure to have a usable mail configuration in SAP that allows for sending and receiving email:

  • External SMTP server. Acts as a SMTP server between SAP and the receiver. This is the email server used to send emails. This can be the official SMTP server of the corporation or any other valid one, like Yahoo.
  • Route for incoming emails. As the MX DNS entry for a domain normally points to the SMTP server mentioned above, the SAP SMTP server won’t receive emails automatically. A forwarding rule between the SMTP server and the SAP SMTP server needs to be configured.

Configuration of SMTP in SAP

The steps are pretty simple. All are to be executed in the SAP system. I used the NPL Gateway Demo system for this.

1. Open the port for SMTP

Transaction: RZ10

In case this was not done before, import the profiles

Select the right profile (here: instance profile) and the Extended maintenance option.

To receive emails on an SMTP port, ICM needs to be configured to

    1. Open the port and to
    2. Use protocol SMTP

Add an entry for SMTP in the instance profile. Here, the port used is 25000.

Save changes to instance profile.

Then save and activate the changes.

Warning message informs that a ICM restart is needed to activate the changes.

Looking in the profile file on the server:

ICM profile file is changed, change is persisted in the file but ICM does not pick up the new configuration automatically. A restart of ICM is needed.

Transaction: SMICM

The Restart option didn’t work for me, a hard exit with a start activated the change. But I am not Basis person.

Confirm the restart of ICM.

Check the SMTP service details. They have to match the new configuration.

Verifying the ICM parameters using SAP MMC.

2. Create system user for receiving emails

Transaction: SU01

Make sure the users in the SAP system have an email address configured.

Here I am using tobias@mydomain.com

With this configuration, email send to the SAP SMTP server will be picked up and delivered into the user’s inbox.

3. Configure SMTP service

Transaction: SICF

Check that the virtual SMTP server is configured

The logon data has to be configured to use the above created SMTPUSER

Handler list

Save the changes and activate the service.

Configure the SMTP server and outbound and inbound flow

  1. SMTP server

Transaction: SCOT

Set the default domain

This domain matches the email domain of the users.

  1. Outbound

View: Nodes view

Set the outgoing SMTP server

Note: This is the SMTP server the SAP system will use to actually send the emails. Emails get send to this SMTP server and from there they are being send to the actual recipient. That is, the server defined has the responsibility to lookup the MX entry of the receiving domain.

Set the address type this node does accept

Note: In the address area, insert the valid format of email addresses. When you insert * the node will accept every email address. To make this node only accept email addresses for a specific user, put <username>@domain.tld

Result in node view

Now the node is configured to accept outgoing emails. What is missing is a job that picks up the emails from the outgoing queue and sends them. Create a job that will send the queued messages

View: Job view

Select SAP&CONNECTALL or SAP&CONNECTINT for sending internet email

To run the job immediately, select “Start immediately”. To schedule a job so it is executed at a defined interval, select “Schedule”

To schedule

Result

  1. Inbound

As long as the virtual SMTP server is activated and the system user has the right permission AND a user with the correct email address exists, inbound processing of emails will work.

As always, great write up Tobias. Do you plan to cover SAPConnect configuration settings, eg. ESMTP? What about security, S/MIME and enhancements?

Thanks Samuli,

 

No, this kind of stuff I'll let to Basis guys. I'm interested in testing. I only wrote this document so I can refer to it in my next blog posts about testing the SMTP service.

Wow, thanks. That's not what I expected to hear.

 

I am sure that I have seen better and greater articles on SCN and there was one where the SMTP configuration was also explained (believe it was part of a greater PI related article?). Just didn't want to refer to other peoples documentation in my next blogs. I am starting to take over SAP's "not invented here" syndrom

For sure there are and that's why I mentioned the above part in my first reply.

What matters is the quality of the article and the uniqueness from the others.

The first picture in yours really made the difference.

Hi tobias.hofmann

 

That's a real great article!! It might also help to set up E-Mails in CRM Interaction Center. We  often get incidents for CRM-IC-EMS but the real root cause is related to setting up SAP SMTP service which is the basis for our CRM IC Pull E-Mail - next time I will propose your article .

Hi Srinu

Have you checked if you have email / outlook integration with your SAP, if not enable and integrate outlook with your SAP System and then check your SOST.

 

have a check if the email smtp port is open for access.

 

cheers

Hello, I was brought to this page from a Search on using authenticated SMTP from SAP.

 

I'm a little unclear on how to authenticate to our in-house SMTP Server..

 

We currently have this working to our in-house SMTP Server with No authentication required, but there is talk about switching to authenticated SMTP.

 

Can you help?

 

Thanks

Hi Tobias,

 

Good day, got a question on the part below:

 

  • External SMTP server. Acts as a SMTP server between SAP and the receiver. This is the email server used to send emails. This can be the official SMTP server of the corporation or any other valid one, like Yahoo.

 

what if our SAP doesnt have ability for inbound email, would there be other way to implement offline approval?

 

Cheers!

Rowie

Offline approval? As in a mobile scenario? There are apps for that, or do you use interactive PDFs?

It is possible to bind ICM to lower ports, like 25. If you want your ECC system to a low port is up to you. I'd not do it, only if I really have to. You should be able to configure your SMTP server to route emails to ICM on a custom port (like 25000).

HI Tobais,

 

Nice document.

 

I have one question.

 

Ex. user is having user1@abc.com in the MS-Exchange while configuring in SAP System for receiving the email do we need to create different email address for this user for receiving .?

 

Do we need to do any additional configuration in Mail Server to receive the same e-mail in SAP SMTP incoming e-mail server ..?

 

Please clarify

Dear Tobias

 

Our systems some times faileed to connect to the SMTP sever while sending outtgoing mails. That time the server fails to send the mails to the recipient and error message 816 appears shwoing red emails. Can there be a system of picking all these failed emails entries to retry to send say after 30 mins again and it should be automatic.

Regards,

Iqbal
