I'm trying to set up a Return-path for Mandrill emails. This is what I currently have:
From: hello@info.example.com
Return-path: bounce-mc.us3_25014995.932533-27c52c08ee@mail52.suw11.mcdlv.net
and I'm wondering how to set up the Return-path header. Would it pass the SPF alignment if the Return-path would be the following:
From: hello@info.example.com
Return-path: hello@bounce.example.com
?
I've found this: https://mxtoolbox.com/dmarc/spf/spf-alignment which mentions couple of examples about SPF alignment but I can't find anywhere in the SPF standard whether if I have subdomains both in the From& Return-path if that'd align just based on top of the top-level example.com domain.
I'm unfortunately not able to set up the Return-path to match the From like so:
From: hello@info.example.com
Return-path: hello@info.example.com
As I can't create a CNAME record for info.example.com as I already have an MX record for this subdomain to route incoming emails to Gsuite (see this issue: https://support.google.com/a/forum/AAAA034zvV85E_AluPsqD8/?hl=en&gpf=%23!msg%2FApps%2F5E_AluPsqD8%2F0x_O1tqmAwAJ&msgid=0x_O1tqmAwAJ)
