I tend to keep a low profile, but I must say that requiring that emails be in text format in case someone wants to build some fragile text parsing thing around them - that will break with the slightest change to wording or organization - seems suboptimal. If there is a need for machine parsing RIPE emails, that should be handled with an attachment in a structured format such as yaml or json.
Though I would also argue that that sort of info should just be grabbed with an API call of some sort and left out of the email entirely.
Maybe things are different in Europe, but speaking of decades, I ran my own mail servers at home in the US for decades. The antispammers have made that effectively impossible, or at least so difficult that the effort far outweighs the benefits. If you send mail directly, you’re typically coming from an address range that isn’t among the blessed, so your mail is treated as spam, and there you are, trying to convince obscure antispam provider #36 that you aren’t a spammer. Personally, I hate that it’s come to this, but it is what it is. I gave in and now I have a Google Workspace account for my household.
I can’t do anything but applaud anyone’s decision to get out of the email-delivery rat-race and just outsource it.
