     Here i have SSHA256 working with:

default_pass_scheme = PLAIN

     and my database scheme just received the hashed password prefixed 
by the SSHA indicator, just like:

mysql> select * from emails where endereco = 'solutti at XXXXXXXXX'\G
*************************** 1. row ***************************
               endereco: solutti at XXXXXXXXXXXXXX
                  quota: 51200
