When trying to configure TLS communication between Email Prevent and MTA the TLS handshake never completes and the following error is found in the SMTPOperational log on the detection server:
(SMTP_CONNECTION.XXXX) Forward connection error (tid=XX cid=Y mta=<> reason=Channel is null in ESMPPerr:recv)
(SMTP_CONNECTION.5203) Forward connection error (tid=XX cid=YY mta=<> reason=Channel is null in ESMPPerr:recv)
SMTP Prevent running in forwarding or reflecting mode
The keystore password may not be set on the Detection server's configuration. This prevents the DLP services from being able to access the keystore when a certificate exchange needs to happen between servers.
