Hello.
I'm having a little issue with my e-mail server, as it forwards CLIENT IP in header (Received: from [127.0.1.1] (unknown [91.123.XX.XXX]) ). What should I do to remove this header from sharing the client IP?

Also, I am having an issue with the IPv6 SPF  (Received-SPF: softfail (google.com: domain of transitioning postmaster@themailserver.com does not designate 2b01:8620:201:20f::67a8 as permitted sender) client-ip=2b01:8620:201:20f::67a8;), also, what should I do in order to get ridd of this softfail?
Thanks!
