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)
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.
SMTP Prevent running in forwarding or reflecting mode
