I am migrating from sendmail my virutual hosting to qmail. But due to some problems I have been forced still to use the /etc/passwd to authenticate the virtual users.
Is there any way out so that I can authenticate my virtual users from /etc/passwd and /etc/shadow instead of /usr/home/vpopmail/domain/passwd file ?
If you are using courier-imap for POP3/IMAP access you can build and configure it to authenticate against the system passwd file. See the docs covering the various authentication modules.
(Hint: look at authpwd and authshadow authentication modules).
