We have requirement to send mail from MII to key users whenever there is specific message is failed in SAP MII, so we need to configure the mail server into the SAP MII. After getting details from the team about the Mail server now its our turn to configure the server into the MII so while doing this job we can’t find much of information on the internet.
After multiple times trying, we were finally able to figure it out so here we are helping the community with our experiments. Please read this blog for configuring the Mail server in SAP MII.
It has three steps in MII as below:

Fig:1 - Create Mail server Name
- Go to the security Services -> credential Store and click on Create.
Fill all required field details on screen with correct server, port and protocol.
