[Dbmail] SASL Auth

[brano]

Hi,
Is it possible to do SASL auth, when I have stored encrypted passwords 
in database?
I get working this with smtpd.conf searched in this mailinglist, but 
only for user accounts with non-encrypted password:

smtpd.conf:

sasl_pwcheck_method: auxprop
sasl_auxprop_plugin: mysql
mech_list: PLAIN LOGIN
sql_user: dbmail
sql_passwd:****
sql_hostnames: localhost
sql_database: dbmail
sql_statement: select passwd from users where userid = 
IF('%r'='dbmail','%u','[EMAIL PROTECTED]')


Thanks,
         bb.
