I hate this comparison. I’ve seen it so many times in the last four years or so, but I feel like it always adds more confusion. I don’t think most people know how email servers work. I run a server and have messed with Postfix, and I don’t have a good grasp on it myself. I’m not sure how to improve it but there has to be something better than that.
This might be a stupid question, but I’m only so-so at wireguard. Do you experience that kind of loss using WG at home, on wifi, between your phone and server?
