-Apart from the lack of TLS, I consider these features. There's no
-(obvious) way for LambdaMail to become a source of spam, the lack
-of multithreaded operation is a built-in rate limiter (not to mention
-its side effect of making all delivery operations "atomic"), and
-its penchant for just responding "250 OK" to almost everything means
-that it doesn't leak information about users on the system.
