shadow passwords

[Anonymous]

I haven't find it in the FAQ in the installation package, so I ask it here
whether qmail-pop3 supports shadow passwords, as it is installed, or do I
have to install something else as well, instead of checkpassword?

My other question is the same for APOP...

The third is, as you can guess... is it possible to do APOP with shadow
passwords? Is Qmail or some extensions able to do it together?
