By Default I didn't get the Email option for Report Delivery option in Scheduling a SSRS.
for this : Run the configuration tool as a Administration ( right click then we will get).
go to Email-setting,
give the details like this
sender : email@example.com
using : SMTP;
SMTP server name : mail.domain.com
for the SMTP server name:
go to outlook
click on File
click on Account settings
here u will get the name and type text box
double click on that
u will get the server information.
