Im not sure which version of Dovecot you're using, because the syntax of
the config file is different in versions from 1.0 and up vs pre - 1.0, but
you need to map some files for authentication (other than /etc/passwd) for
both Postfix and Dovecot if you're doing virtual.
I'm running Postfix and Dovecot with virtual domains (including the main
hosted domain) and have added Dovecot SASL support and it works well. I
found alot of information at the links listed below though the SASL stuff
was elsewhere. Note the way the last link shows the structure of the
dovecot userdb and passdb files, I'm using plaintext, not MD5, but the
idea is the same. Hope this helps.

Chas.
