My server sample.net setup Fedora core 3 + Qmail + Vpopmail 5.4.13+ Courier-imap 4.1.0 (courier-authlib 0.57) -----> /var/qmail /usr/local/courier-imap ( /usr/loca/courier-authlib) /home/vpopmail

Qmail and Vpopmail work ok. I can send and receive email via Pop3d of Qmail with user created by vpopmail tools.

When I installed courier-imap (COURIERAUTHCONFIG=/usr/local/courier-authlib/bin/courierauthconfig \ CPPFLAGS=-I/usr/local/courier-authlib/include \ ./configure \ --prefix=/usr/local/courier-imap \ --disable-root-check \ --with-ssl --with-redhat) and config courier-authlib for use authentication module: authmodulelist="authvchkpw"

And I can't use this imapd service, here some my test, you can check :
