After a long hiatus, I’ve updated courierpasswd, my checkpassword-like utility with hooks into the Courier authentication library. Courierpasswd now logs the IP address of hosts when they attempt to authenticate. My motivation for adding this feature was to track remote hosts trying to authenticate against my SMTP server. This version also adds sha256 as a valid CRAM type since sha256 is supported by the Courier authentication library. You can find more details in the Changlog file.
