It +is probably best defined in terms of what it does not support: + +- It does not (yet?) support TLS connections. +- It does not allow outbound connections. +- It does not spawn threads to allow simultaneous inbound connections. +- It does not respond with honest errors on failed deliveries. + +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. + +LambdaMail is still under active development and, given that it was +written for a single use case, lacks any documentation. However +it's a pretty simple Scheme program, so glancing over the code should +suffice. + +License +------- + +LambdaMail is free software, and is made available under version 3.0 +of the GNU General Public License.
