[Dovecot] Hybrid of linux user accounts and virtual user accounts configuration

[Derek Winterstien]

Murry – my mail delivery is working fine.  The 
first message even automatically creates the 
Maildir structure like it should, all permissions correct.

Steffen Kaiser – I will place the output of 
dovecot –n at the bottom of this message.

I've configured checkpassword which should be a 
script that comes with dovecot.  However, I cant 
find it in my install
. Which I thought was 
standard. Not sure where to go get it from either.

See this error from the log:
dovecot: auth: Fatal: 
execv(/usr/bin/checkpassword) failed: No such file or directory
dovecot: auth: Error: 
checkpassword(foo,127.0.0.1): Child 29179 exited with status 84

And the pop client sees:
-ERR [IN-USE] Temporary authentication failure.

Isn't it a script rather than a binary?
Is it what should be using to read my simple virtual user flat text file?
