courier question

[Igor Gueths]

Hi all. I'm attempting to set up Courier here, except I've run into a 
problem related to the various authentication modules. In 
/usr/lib/courier/etc/authdaemonrc, the only modules that are in the list 
are authcustom, authcram, and authldap. What exactly is authcustom? 
Also, the install file says that configure is supposed to install the 
correct modules for your system...Where is authpw and authshadow, and 
authpam? Bc theoretically, these modules should have been installed. I 
am using shadow passwords, and I know I can use pam because I have 
configuration files for it in /etc/pam.d. Is this a case of configure 
not guessing correct values, and I have to explicitly specify the 
modules I want to use? I currently have Courier-0.44.2. Anyone know why 
I am getting this strange behavior? P.S: Just for testing purposes, I 
started courier and echoed a message to postmaster, who I aliased to my 
main user account (igueths). I created a Maildir, and then sent the 
test...Sure enough, no message present when I tried to read it with 
Mutt. However, all the syslog messages indicate that Courier 
successfully sent the message...No errors.
