I have been the one who had this problem.
We reached some kind of conclusion (see below).

I tried also all these combinations with no success.

I wrote a bug-report, but nobody seemed to be interested. (I will have a quick 
look into the tracker when I've finished this mail, but I don't think 
anything happened).

Erwin Hoffmann ( spent some time looking through the code. His 
personal summary was that the easiest way would be to rewrite the whole 
vchkpw because there seems to be quite much unused and/or useless (and 
buggy(?)) code which makes it really hard to do a debug of this problem.

But: We found a workaround!
1. Take vpopmail in any version of your choice, configure, compile and install 
2. Take vpopmail-5.2.2, configure and compile it. Do NOT install it!
3. Rename your current '/var/vpopmail/bin/vchkpw' in whatever you want.
4. Copy the vchkpw-binary from your vpopmail-5.2.2-directory into 
5. Test it. See that it works. Have fun.
There is only one disadvantage: CRAM-MD5 doesn't work with 5.2.2.
Everything else will work fine (I am running it against MySQL without any
