My inclination is to say that your design is broken. Talking SMTP is a Hard Thing, which is why most antispam stuff sits as a plugin to the MTA proper, so somebody else (the MTA author) gets to deal with all this mess. (As a side comment, I don't like your approach of hijacking exim's SMTP conversation in progress: better for your code to talk to the outside world and have a separate SMTP conversation with exim starting when it's happy.)
Of course, if you really want to write an all singing all dancing antispam front end, feel free, but I predict that getting it write will be more work than the other approach.
