Hi Casey
Pretty easy with the new 7.1, go to Web configuration/Mal Services/Sending
You can set up your smtp connexion to your SMTP server either for plain notification and/or for workflow notification
I guess you might not be concerned but is's better to know that there is currently a bug if accentued characters are used in the email subject. (sounds like it is related to 7 versus 8 bits character set)
Hope it helps
Regards
Gilles
