Configuring SAP SMTP service 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 wont receive emails automatically. A forwarding rule between the SMTP server and the SAP SMTP server needs to be configured.

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 didnt 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 users 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.

a. 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 @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

a. 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.
