Want to Add X-Originating-IP in Header

[rccess]

This Concern already opened in issue #1418

Would like to have discussion on it

I want to add X-Originating-IP in header which is server sending IP

Want to add into postal/lib/postal/message_db/message.rb

I tried to add in client.rb with the following pattern with 4 options , none working

headers << "X-Originating-IP: #{self.ip_address}"
headers << "X-Originating-IP: #{@ip_address}"
headers << "X-Originating-IP: #{self.server.ip_address}"
headers << "X-Originating-IP: #{server.ip_address}"

Please do advise on the same

any other way if we can pick this IP from spf or PTR , since it comes in header already for PTR and SPF
