I had a good productive day today. I have:
1. Put a new SMTPd in place on our spamtrap that uses my epoll/kqueue/poll stuff. It seems to work nicely (though I'll disable it for the weekend - just in case).
2. Updated some parts of our anti-spam infrastructure to fix some bugs.
3. Written a plugin for my home smtp server (qpsmtpd) to reject all "foreign" emails.
Now I'm off to the bank since today was payday :-)
