Has anyone successfully automated sending neomail messages recently?

TNT really fucked with the code on that page, and even nearly 100% imitating a real message (using charles to verify) doesn't do the trick.

Using python:
The only thing in the request I haven't gotten the same is the "Connection: keep-alive", since mechanize doesn't support it. I almost have gotten to the point of using a different module that will support it (even though it seems odd that this would cause the problem - or is it not odd?)

I should mention I'm not building any sort of spambot bs. I'm looking for easier ways to reply to messages using my own format is all.
