Ronald, my two cents on this:

There are many SMTP relays in the world checking SPF record for the incoming mail and providing a diagnostics with openspf.net web. But unfortunately this website is down for almost two years and this diagnostics leads to nowhere. If someone is running a mail relay, then now is a good time to check its responses. -- Kind regards, Sergey Myasoedov

Some days I am inclined to wonder how or why anything at all actually works on this planet. I suspect that I am not alone, given that Covid-19 has now exposed for all the world to see just how inept and dysfunctional even so-called "first world" systems are at dealing with anything that is even just a little bit out of the ordinary.
Another case in point: AS16019 aka vodafone.cz, whose formally declared abuse reporting address, as given in the WHOIS record for the ASN, is abuse@vodafone.cz. Unfortunately, if you send a copy of a spam that you have received from their network to that address, you will get back something that may look vaguely like this:
<spamrd@vf.dkm.cz>: host mail2.dkm.cz[62.24.64.36] said: 550 5.7.1 <spamrd@vf.dkm.cz>: Recipient address rejected: Please see http://www.openspf.net/Why?s=mfrom;id=rfg%40tristatelogic.com;ip=80.95.99.97...
So, the retorical question for the day is: Just how completely idiotic does any given group of network operators have to be in order to be unable to just simply operate a functioning email address for inbound messages?
I guess Vodafone is either too broke or too cheap to hire merely competent people.
It would be one thing if this was an impoverished third-world country involved here, but it isn't. It's the Czech Republic. So what is their excuse for this level of sheer incompetence?
Does someone need to send a formal memo to Vodafone, explaining to them about this thing called spam?
And why are they even leaving port 25 outbound open on end-luser lines?
