Start Subject LIne with specific text

[Coleen_Astalos]

Is there a way to start the subject line of the instant emails with a particular specified text?

My users are having a hard time setting up rules in their email programs and are used to our Yahogroup which appended SU!: at the front of every email.

Thanks,
Coleen
