I'm fairly new to the IceWarp Administration tool, and I'm trying to figure out how to add on to the beginning of a Subject line with the "Edit Message Header" rule.

I have the Action being Add/Edit, then the Header being Subject: but I don't know how to get the value to change to add text or a symbol in the subject line (I want to keep the original sender's subject line, just add to it).

Thank you!
