Have to add my endorsement here. I spent far too long setting up postfix and working on some test code with lamson. In the end, I decided to try out Mailgun -- 2 hours later I had a working solution for parsing email responses. Good stuff.
Best part of working with Lamson? A dependency on a module that massively reorganized itself in a very minor version change, leading me to have to search back to see which version it worked with. Was it 2.8? 2.7? 2.6? 2.5? Aha, 2.5!
