Description:
This is an SMTP protocol log for virtual server ID 1, connection #505. The client at "203.52.224.164" sent a "xexch50" command, and the SMTP server responded with "504 Need to authenticate first ". The full command sent was "xexch50 2584 2". This will probably cause the connection to fail.
