Postfix- Why do we need Db, Cyrus sasl and open ssl

Hi,

I'm trying to setup postfix 2.1.1 which is customized to use our spam filter, in sparc solaris 8  platform.
1) Curious to know the roles of Berkely DB, Cyrus sasl and Open ssl in postfix setup.
2) How to check whehter these components already installed in the machine?
3) Will copying the \usr\postfix  directory of one machine (where already postix running) to another one will also include the above components like db, sasl  and open ssl?

SSL, SASL and Databases are external facilities which are not part of postfix.
I am not familiar with solaris enough to say how to check if these things exist or not.

Copying a postfix folder will almost certainly NOT copy those components.
