I already did 1) - that's working fine.
2) is becoming frustrating.  I thought net_ip2addr() would be what I
needed, but I guess not.  Although I only used (char *type) not (const
char *type)..   No compile issues, nothing.  It doesn't appear to even try
and write to the table. (I locked the table to see :)

For giggles I tried using checkpassword just to see what would happen
(though I know it works for qmail-pop3d), but apparently Dovecot can't use
checkpassword with CRAM-MD5 :/   Not sure if that's a bug or expected, but
means I can't convert.  I don't want to remove functionality.

I don't expect much more help unless you see something jump out - This
function just returns an error if MySQL throws an error (in vpopmail's
vauth.c), any other errors and it's silently skipped over - so
troubleshooting this is going to be a little drawn out.

Thanks,

Rick
