[HECnet] Mailing list...

Hi, all. I have an issue with some mail servers/providers that some people use. I'm open to some suggestions, but also want to point out something to people who are subscribed. Sometimes I start getting mails bouncing for some subscribers. I do try to check why, and occasionally there have been something I could do about it, but many times it's simply what I would call a broken mail server for which there isn't much I can do. So occasionally I unsubscribe people for which I'm just getting bounces all the time. One such example is one server who claims that 130.238.19.25 don't have reverse DNS. Which is clearly incorrect. It have had proper DNS setup for at least 20 years. I have no idea how that mail server is set up, but I can't do much about it. Other times mails gets denied because of some blocking service who thinks the hecnet mails are just spam, or the host (Update) is untrustworthy, or have a bad reputation or what not. Usually not much I can do about those either. If people (or companies) decide to make use of such services, and such services give that kind of information, it essentially just means that you'll not be getting the hecnet mails any more. There is only so much I'm willing to do to try and sort such things out. I do consider such services and solutions to be fundamentally broken to start with, but I will of course not say that people can't use them if they want to. But chances are that you'll get dropped from the HECnet mailing list sooner or later, unless you are using some service/technology that actually do work (not sure if any such exists). An example I got today (actual mailbox names redacted): reason=CH ? What does that mean. The mail is rejected because it came from Switzerland? (Yes, I do live in Switzerland, and yes, it was a mail I sent to the list, but really? Is all mail from Switzerland suspect now?) Rejected due to local policy? Following the link don't really give an answer, but just various recommendation. Most of those recommendations are already done (and have been the whole time) by the HECnet list. SPF and DKIM we don't use. I had that setup for a while on a mail server of my own, and came to realize that it hurt more than it helped, so I removed it again. I doubt this will be setup on Update any time soon, but either way, it's not there now, and it's not even clear if that is the reason for the rejects, or some other thing. There is also no way to even get in touch with Apple in this case, to fix this. So there is a fair chance I'll have to unsubscribe a few more addresses in the near future... I am not really interested in moving the mailing list to some other host. Any suggestions from anyone on this topic?
