But in the case of SMTP it is a TCP Communication between a Client and a
Server, so in light of that I think it would be incomplete, not to log the
client IP at a bare minimum.
Not sure if your DRIP requirements provide any examples of communications
that include an IP address but do not include a port.
And, I can't tell you about my conversations with CAC, but I did start
logging port information right after I spoke with them.

This may also be of interest to you.
