Here are a couple of one-liners I have used on Lotus Protector for Mail Security:
1. This one shows where your server is attempting to get its updates. Substitute the server's IP for "x.x.x.x" and your own IP (or part of it to exclude the whole LAN subnet) for "y.y.y.y". If you watch the output for "S" packets that have no corresponding "F", that's a timeout and you need to allow HTTPS access to that destination on the firewall.
update-control -f & tcpdump -ln port 443 and src host x.x.x.x and host not y.y.y.y and 'tcp[tcpflags] & (tcp-syn|tcp-fin) != 0' | awk '{print $5,$6}'
2. This one shows who has sent you mail in the past 24hrs without TLS encryption, sorted by domain. It is likely lots of spam and newsletters, but you may be shocked to see how much of your incoming mail is being carried in plain text. Note: this only works with the latest firmware 2.8.1
