How to set dynamically FROM or REPLY-TO with "share page" Email?

I would like to set FROM (better REPLY-TO) to the current users email address “$xwiki.user.getEmail()”, especially within “share page”.

Just setting values to “Email address sent from” to “xwiki.user.getEmail()” or “$xwiki.user.getEmail()” or something like “smtp.mail.from=…” in “Additional Properties” does not work.

(Users typically use the “reply”-button of their email client …)

Is this configuration possible ?
