Maintain Reply-To header for outgoing Emails

Dear Experts,

I have a requirement to configure outgoing E-Mails from a service ticket in such a way that From address for the outgoing E-Mail is if filled by the E-Mail address of the responsible employee whereas I should maintain a reply-to header(for group e-mail) so that when the recipient replies to the e-mail, the receiving address should be group e-mail and not the e-mail from which we sent the e-mail.

I have maintained the E-Mail profile and the Reply-to address in the email profile. But this is not working the way I want to set. I have seen the MIME document in the SOST transaction, no Reply-To header is available.

Is there any customization that I can maintain or any custom code that I should write to fill the Reply-to header?

Million thanks in advance for your help.
