This is a post about the biggest cult in privacy community witch hunting, and you do not recognise it.
I do recognize it because you talked previously about it. I just don’t think it’s pertinent to show in this form for people who don’t know about the entire story (even i don’t know the whole story). I would recommend either to make a community dedicated to this topic, with a stickied thread serving as introduction, or to give more context to your post on the topic. But shitposting random conversations about a topic of interest of yours into random communities is not really cool for people who do not reside in your brain :D
Also, bit of personal advice: you seem really obsessed with this community and story. I think it would do you good to focus on something else… You seem to imply it’s a “big” thing but seriously i’ve never met a single person using GrapheneOS and they only support Google phones so there’s no risk it’s becoming a big thing any time. Maybe try to get involved in Lineage or /e/OS or PostMarketOS communities? You may help build the mobile distro you wanna see instead of loosing a little bit of your sanity every time the GrapheneOS mods do something. Take care :)
Sounds like a bug. When you turn on debug logging do you see anything specific? (i don’t even know if debug logging is a thing in Lemmy ansible setup). Can you maybe also try with another SMTP client like msmtp to see if you can reach your mail server from it? It’s possible that some network misconfiguration prevents it, or that your mail provider has blocked your IP/range for some reason.
