@girish Ahhh ... I think because the settings section didn't populate with Gmail.com after I established this as the outbound, I figured this panel was inactive and overiden by my new outbound settings.
I now see that this panel will still set the from name and reply to address while the sending address will come from outbound.
It might still be nice if the gmail our newly-established outbound address populated in this panel once established and then users could also use this as a reply-to address? Or even better - an ability to set any chosen reply to address not tied to this server like I might just want to put "myname@maincompany.com" as my reply to instead of the server domain ... I guess a work around is to create a forwarding address but that's additional work.
Just a thought. Great work, again.
