My topology is as follows..
1. Postfix mail gateway which ultimately invokes dspam content filter
which relays the email to backend mailbox server.
2. The backend mailbox server runs both postfix and dovecot.
It appears it tried to send email to itself. As per configuration
below, a dovecot delivery agent should be called. Why is it not being
called?
This is the message I am getting on the backend mailbox server..
