Yes the Linux Foundation guys are not willing to address this issue in any
way. I may have to give up my linux.com email address.

It looks like you have to linux.com emails through their SMTP relay,
just like kernel.org ?

No they do not offer an SMTP relay. That would actually fix the issue.

I have an exim config that auto-routes to an authenticated smarthost
based on the From email address if that would help you

I am running a mailer too but that does address the issue of not being
able to setup the SPF records for me on linux.com.
