To answer my own post, I found in some past notes something I drummed up
quite a while ago that I can most certainly modify to suit my needs:
# Cat the tcpdump output file
# confirm that the source IP is NOT the mail server, and print the
source IP/port
# separate the IP/port entries
# eliminate only the port and print IP
# clean out the spaces in the IP
cat tcpdump.txt | awk '{if ($3 != "192.168.100.204.25") print $3}' | \
awk '{FS = "."} {print $1,".",$2,".",$3,"."$4}' | sed s/" "//g
