The bigger question is - how does the BOSS know there was a 30 second
delay in incoming email due to virus scanning?
Some emqil configurations also use a multi-queue system, where a second
daemon cans the 'clean' incoming mail for delivery, so there is a
built-in delay of 10-15 seconds.

The answer to that solution is to use multiple front-end servers that do
filtering and scanning, then posting clean email to a back-end server for
delivery to user mailboxes.
There are multiple ways to load-balance incoming email to the front-end
servers.
