i am using dovecot as proxy in front of dbmail
since 2009 and for sasl auth because this way
you have ecryption, CRAM-MD5 and so on for
IMAP as also the same SASL auth mechs for SMTP
if postfix is using dovecot for SASL
the sql-config below is for a localhost where dbmail-imapd
is listening on 127.0.0.1:20143 and dovecot on 0.0.0.0:143
