I've just deployed a HP LeftHand p4300 SAN.  I'm not attempting to configure email alerts from the Nodes and have come across the following error

Failed to sent Test Email because of the following error:   Email SMTP status 553, message: Invalid CHUNK size value.

My configuration has the LeftHand Management Console multi homed between the iSCSI network (10.10.10.x) and production network (192.168.0.x).   The IIS SMTP Virtual Server is installed and relaying messages to an exchange server on the production network.   I have tested and confirmed I can email from the Management server to external accounts.  

Unfortunately I have also confirmed with LeftHand support that they have come across this issue before and inform it is an issue with the Mail server not accepting the 'CHUNK' size of the mail being sent from the lefthand.  They don't have any answer or work around to the issue even though they have seen it before which I thinks a bit of a cop out.  

Help would be most appreciated.
