Could it be that authentication depends on a daemon and that daemon isn't in 
your start-up scripts?

But without details of how it was configured I'm just guessing.

So it could be as simple as: "/etc/init.d/courier-authdaemon start"

And then ensuring it is in the start-up.

Post here output of postconf, and also any errors, and others can probably 
give more specific advice.

Thanks for your consideration
I run "/etc/init.d/courier-authdaemon start" it is done but nothing change I 
still receive the error. I don't know how to ensure it is in the start-up.
you can find output of postconf as a attachment
if I don't use secure authentication  (SSL)  thundarbarid ask me to enter 
password and after that I receive this "login to server mx.mydomain failed "
