Its perfect for a small VPS. Been using it for years.
I do occasionally get places where my email simply will not send to them, even though it follows every email standard properly and isnt blacklisted. For those rare occasions, ill use a third party email address to send, which then forwards everything to my main email.
My solution is to avoid services that are anti-lurker.
If im not able to view it without logging in, i just accept it, not watch it, and move on with my life.
