Messages added to /var/log/messages with the following command are
displayed almost instantly, though they aren't exactly readable since the
text is shown as a hex string:

sudo echo "Another message" 2>&1 | logsave /var/log/messages -

Changing the listener to

$ sudo tail -f  /var/log/maillog | awk -- '{ print $0 }'

so its looking for messages sent to  /var/log/maillog and then running

$ sendmail -?

which runs sendmail with invalid parameters shows this fatal message
being logged almost instantly:

 fatal: usage: sendmail [options]
