Hi,
I change this

auth default {
  mechanisms = plain
  passdb pam {
    args = "dovecot"
  }
    passdb passwd {
     }
  userdb passwd {
  }
But i have the same error :

telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
+OK Dovecot ready.
1 login toto mypasswd
-ERR Unknown command.


telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK Dovecot ready.
1 login toto mypasswd
1 OK Logged in

In pam.d/dovecot, i have
auth       required    pam_unix.so nullok

account    required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth

In pam.d/pop3, i have
auth       required     pam_nologin.so
auth       include     pam_stack.so service=system-auth
account    include     pam_stack.so service=system-auth
session    include     pam_stack.so service=system-auth

and in pam.d/pop, i have
auth       required     pam_nologin.so
auth       include      system-auth
account    include      system-auth
