Hi Evan,

Not sure how far away with your MTA, but I'm building a full MTA using
gen_smtp (with connection pooling, per domain throttling, several queues
optionally running on a cluster, web gui, etc.). Doing some testing in a
production env, right now then I'll put it up on github (
https://github.com/zsolt-erl). Maybe you can just add SPF handling to it.
I'm not sure if SPF is that much useful but I'll add dkim in the future (for
now I'm just using dkimproxy <http://dkimproxy.sourceforge.net> ).
