I've installed (and removed due to mailstrom) version 1.890 of webmin. I was using version 1.881. I've configured logging /send log actions via email in all of the previous versions of webmin and got an email whenever a configuration change is made. I haven't configured sending email with webmin, but I'm using SSMTP to send emails from this system, as I need to be able to send emails from scripts, using echo to SSMTP. As of version 1.890, all of the entries in the "webmin scheduled funftions" ('scheduled cron jobs' and 'system status' are sending emails, whenever they run. this leads to an email for 'system status' every 5 minutes' and an hourly mail for 'cleanup tmp files'. These mails where never send in v1.881, even though the same jobs existed. At the very least, there should be an option (in each job?) to suppress the email notification. Something has definitly changed from version 1.881 to version 1.890, this makes webmin v1.890 unusable on my system
Using raspbian, witch is reported in webmin as debian linux 9.4
same problem in version 1.900. Unable to use the latest versions due to mailstorm
You can configure in the Webmin Configuration module which other modules to run the action script for.
