IMAP and SMTP "Heartbeat" Tests?

[Jerry Malcolm <te...@malcolms.com>]

I am in the process of writing AWS Synthetics Canary functions to 
continually check the health of the my JAMES IMAP and SMTP servers.  I 
know I could set up a full IMAP or SMTP session with id/pw and try to 
read mail with imap and send something with smtp.  That would definitely 
prove that IMAP and SMTP are up.  But I'm just curious if there are any 
simpler heartbeat-type requests that I can make to each server where I 
can determine if the servers are still up and running.   I'd prefer not 
to have to send an email continually every 5 minutes.  Has anybody got 
suggestions for the best way to get do a heartbeat test om IMAP and SMTP?

Thx

Hello Jerry,
Did you use guice health checks?
https://james.staged.apache.org/james-project/3.7.0/servers/distributed/operate/webadmin.html#_healthcheck

We already have health checks:
 - Correct application startup
 - For backend components
 - For functionalities like email reception.

The framework to check James overall health is IMO health checks. We could
allow users to write and load health checks as extensions (like mailets).
