Fernando - We spent some time this morning working on this issue. Right now the adjustment we have made to it to allow larger emails to come through without bringing the email system down. Initial testing looks good. This is a short-term fix to make the system more resilient.
Peter - this is something we would like to do someday. It appears right now we would need to change email systems to make this happen, so it's a pretty large piece of work to replace all that code. Still not ruling it out, but for now, we are focused on making sure the system doesn't go down when someone sends in a large attachment.
