I've been made aware that in the latest 60.4 changelog
(http://www.courier-mta.org/authlib/changelog.html), the authvchkpw
module has been dropped.
What needs to be done to have it put back in? I'm assuming a
maintainer, but I'm sure there's a lot more to that.
Yes, someone need to take ownership of the code.
(There are a _lot_ of us out there with vpopmail installations that use
Courier-Authlib and Courier-IMAP)
In most cases, you should be able to use the authmysql module.
