We would recomend SMTP configuration for best results when using WinSPC with external E-Mail for the following features:

*E-Mail Triggers for Control Test rule violations in Data Collection mode 
*E-Mail Notifications for failures to collect data using Timed Data Collection
*E-Mail PDF reports directly from the preview report window
*E-Mail Actions in Dashboards in WinSPC 9 and above



Prerequisites
*You will need either the IP address or the Server Name of your SMTP server.
*Port 25 must be available on your SMTP server.

Steps
1) Log into WinSPC as the ADMIN user. (No other user can make this change).
2) Browse out to Tools-->System Settings...
3) On the E-Mail tab, select the SMTP radio button option.
4) Enter either the Server Name or the IP address of your SMTP server.
5) Enter a Default Sender E-Mail address. 

NOTE: A default sender E-Mail address must be used. This is an address used for named recipients to respond to if the WinSPC User does not include an E-Mail address. Some customers who do not require responses to triggers use addresses like:
No-Reply@YourCompanyName.com
