I am trying to understand the benefits of BSMTP, but must admit I do not quite understand the concept of it.

What are the main differences between BSMTP and simply forwarding an MX-record?
What is the difference between BSMTP and having a fallback MX?
Are there any downsides to using BSMTP?

Hopefully you can clear this up for me. Thanks in advance!
