Update university article - Advanced SMTP settings and Trigger creation

Some navigation info is incorrect in this connectwise university article. 

- https://docs.connectwise.com/ConnectWise_Control_Documentation/Supported_extensions/Administration/Advanced_SMTP_Settings

It appears to be out of date, the steps I use to access the advanced smtp settings are as follows: 

Click on "Admin" on the left nav column -> Click on "Mail" in the list of menus -> click on the "Edit Mail Configuration" button in the upper right hand of the page. 

Also, some notes indicating that it doesn't play well with sending to multiple email addresses in the documentation for setting up a trigger would probably help out as well
