Email Options 
Use the vBulletin Options > vBulletin Options > Email Options setting group to setup the behaviour of your email features throughout the board.

Here you can setup everything related to how your forum sends and handles email.
To obtain your SMTP information, you will need to contact your SMTP provider. This is not information that can be obtained through vBulletin or from support staff.
