I also worked a bit on the go-opensmtpd package and made progress on the filter API, the goal being to allow writing a filter without worrying about the low-level protocol. Instead of reading the protocol, parsing it and determining what should be called or not, a filter can register callbacks for specific events and implement these callbacks.

I have very recently worked on abstracting the API version on opensmtpd-filters-go. Usage example can be found here: opensmtpd-filter-greylistd/main.go.

I am looking forward to seeing on how you're going to approach the problem :).
