Automated reply using sender's subject line

[Castor]

Hi,

I have set up a ruleusing Rules Wizard that sends an automated reply back to
the sender of an email. I am able to customize the body of the message of the
automated reply; however, I am trying to keep the subject line the same as
the subject line of the original message that was sent to me.

Is there a way to make that happen? Tks a lot! Castor
