No irules are necessary. You must simply disable SNAT. When BIG-IP receives a connection, the source address is translated (or not) depending on those settings. The GUI path is: Local Traffic => Virtual Servers => (your smtp virtual) => Source Address Translation none means "don't NAT source address"
