Using Courier Linux Mail Server and getting 00020 error after sending a report with MAILSPLF.


In the Courier config files (ESMTPD file). Change the settings for DUNCANDO. Turn off DUNCANDO. After a connection, the Courier mail server was sending back 2 packets instead of 1, thus causing confusion to the MAILSPLF command.
