No Spam Filter
This has to be the only email service, well, call it service, with no spam filter. You can mark an email as spam but that doesn't stop further spam emails from the same address, I'm getting more spam than legitimate emails. Apparently, you have to do nothing else all day but to manually copy and then go somewhere else - who knows, and then manually block it, then go back and do the same with the next spam al infinitum
