this is my situation, one qmail+vpopmail(MySQL)+dovecot server that
works like an MX record and provide access on mailbox via POP3 or IMAP.
Another server with postfix and SASL for SMTP-Auth only, with SASL that
query the vpopmail DB for user authentication.
My intention is to set a query into SASL for use the same flags for
SMTP-Auth that read vpopmail and qmail.
Do you run dovecot? If you do, just make use of dovecot's sasl
provisions. That is supported by postfix.
