Email Configuration(Sending Mail from SAP)

Steps to Sending Internet Mail from SAP R/3
As of SAP Web Application Server 6.10, the SAP system’s kernel supports SMTP (Simple Mail Transfer Protocol) directly, meaning that e-mails can be exchanged between the SAP system and any SMTP-compliant mail server without the need for any additional external components.
SAP OSS Note 455140 can be referred for Configuring Internet Mail in SAP R/3 WAS 6.10 and above & the following steps are to be followed for the same;
Changing Profile Parameter (Txn RZ10)
Following 2 parameters to be included in the instance profile Parameters
is/SMTP/virt_host_0 = *:25000
icm/server_port_0 = PROT=SMTP,PORT=25000
Save/Activate the Profile & R/3 Instance to be stopped/Started
User Creation (Txn SU01)
This user will be used for the process of sending outbound e-mail from SAP R/3, as a background process.
User ID mailadmin user to be created with profile S_A.SCON & type is System User.
Client Assignment (Txn SICF)
In transaction SICF, there should be one SMTP server (called SAPconnect) supplied in every SAP system. Use this one for the first client then create (if required) an additional SMTP server for each additional client. Following settings are to be done;
Host data
Profile Parameter No. : 0
Service data
Client & user details entered (say client 100 with user mailadmin)

SAPconnect Administration (Txn SCOT)
Make the SAPconnect settings in each client that is to be used to send communications.
