Marco,

Cyrus SASL supports auto_transition (sasl_auto_transition in 
/etc/imapd.conf).

If enabled, and authenticating using PLAIN or LOGIN, you can have 
your daemon write all usernames and passwords, in cleartext, to 
an auxprop store backend such as /etc/sasldb2.

That should be true of Cyrus IMAPd, Sendmail or any other daemon 
which calls Cyrus SASL during authentication.

You can also configure the daemon to include saslauthd in the 
pwcheck_method/sasl_pwcheck_method configuration option, which 
will give you the ability to authenticate to a (local) passwd file.
