receiving and associating emails to single a/c

Hi,Looking for advice.Scenario: we have a dmz mta that currently redirects received emails for a selection of email domains to specific internal ms exchange servers. We want this mta to redirect incoming customer emails directed to a set of email addresses numbering about 30, to a dovecot server and associate these emails to a single dovecot user account so that a contact Centre platform can pull these emails on a frequent cycle.How to go about configuring this on the dovecot? I assume a postfix server needs to be installed on the dovecot server for the dmz mta to send these emails to dovecot inbox? Any advice most appreciated. David.
