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?

dovecot -n
