FWSM dropping ESMTP packets?

We have an FWSM 1.1.3 connected to a CSSDMZ we took several captures and noticed that ESMTP packets were establishing the handshake through port 25 but doesnt pass the message body "helo" to the inside. Server 10.60.5.54 is connecting to 172.24.6.70 through SMTP. We are allowing all communications from the DMZ you can ping the server etc...Any ideas?

Re: FWSM dropping ESMTP packets?

If the connection was torn down by a re-set flag in the TCP header, and if the reset flag is sent by the client, then FWSM tears down the connection.

If the websense server is configured, it generates the reset packet. When it is disabled, the issue will be resolved
