["andypiperuk@xxxxxxxxx" <andypiperuk@xxxxxxxxx>]

So just using QoS > 1, switching off clean sessions, and using a static
client ID for the subscriber...

Publisher:
mosquitto_pub -q 2 -t test -m "andy"
mosquitto_pub -q 2 -t test -m "andy 1"
mosquitto_pub -q 2 -t test -m "andy 2"
....

Subscriber:
mosquitto_sub -c -i sub1  -t test -q 1
<kill or ctrl-c>
mosquitto_sub -c -i sub1  -t test -q 1
(receives messages sent since it was killed)
