I talked to Barracuda today, their response is that very very little spam will ignore the MX rules and go directly to iMail. (little = 2%)
yes, but 100% of the 2% is spam, and in many quarters, 2% spam passed is a lot.
Also, does that 2% include msgs to unknown recipients, because if it doesn't they are understating the non-MX port 25 problem.
