The end user should type the correct password.


Seriously, you didn't give us anything much to work with here:

You mentioned that postfix is in use, but this seems to be a strictly
Dovecot related problem, right?

Have you checked the Dovecot logs for any reported errors?

What is the authentication back-end you are using?

Are you sure the user /does/ have the right password?

Does this happen for all users, or just some?

Where are the accounts coming from, the Unix password database, LDAP,
a virtual store of some kind, or what?
