The only way to be sure is to try it.

This would be, I assume, the IP assigned to our server?

Would be worth a try, although the test results above don't indicate either SPF or DKIM failure.

As I read for further on this, I think you've got it backwards. I think this would say that people could send mail claiming to be "From" my domain via any SMTP server they pleased. This would make it easier for me to send mail using my address on the BBS via my home cable ISP's server, for instance, but it it would also permit any spammer to make up any address he wants on my BBS domain and send mail coming "From" there with impunity via any server he has access to.

I think what I would need is for the SPF record for each of my users' email domains to have an entry allowing their mail to be sent from my server, and there's no way that can happen.
