Set 'replyTo' for SMTP

Hi, I’m using wM v6.5

Currently, this is my requirement:

I’ve checked the ISBISReference.pdf.
There’s a service called pub.client:smtp

There’s an input field for ‘to’ and ‘from’.
Is there any service in IS that is similar to this ‘smtp’ service, that enables me to add in the ‘replyTo’ section? Or do i have to write a java code for it?
