Hi,
There is a solution, using syslog.
In my case:
- Total# of legit mails-connections (connection get passed SMGs firewall-rules): grep -c "|ACCEPT|" logfile
eg Feb 23rd: 300.914
Beware of the outbound connections, possibly change in grep ;-)
- Total# of TLS-Connections (ok, only know TLS, version is not logged): grep -c "|TLS_RECEIVED|yes" logfile
eg Feb 23rd: 118.839
Hope it helps
Regards
Thomas
