Hi,

I have a forum user with an email address at gmx.net who had difficulty registering to the
nabble associated mailing-list (lists.openscad.org).
i.e. his forum posts were flagged 'This post has NOT been accepted by the mailing list yet'

I ended up sending an invite, and he got registered. His mailing-list setting seem OK.
He is getting the general posts (ie others posting on the forum) as emails from the list, but whenever he posts
the email to him gets rejected with the post-office message below. So his forum posts are still flagged as above.

Hence not many see his posts - somewhat frustrating.

The error is a SPF rejection. Does openscad.org need a SPF record? I'm no email specialist.

Thanks,
Michael,
newly minted admin for forum.openscad.org
