Increasing parsing size of Mail_lua for large emails

[DionStempfley]

We are capturing email delivery from our Ironport ESA inbound to Exchange and the messages are bulk delivered by IronPort.  We noticed that when there are a number of large messages in a single bulk that meta is generated for only the first one or two messages.  We are looking for a way to tell IronPort to separate the messages and not bulk deliver, but that doesn't seem to be an easy thing to find.  For now, can we make a change somewhere to increase the max message size that is parsed by Mail_lua?
