There is an issue with sending e-mails via Exim. By default, Exim tries to send e-mails from @helos. With Monit this prints "<monit@helos>: Sender address rejected: need fully-qualified address" in the Exim logs. With "echo "This is message body" | mail -s "This is Subject" christian.dueben@uni-hamburg.de", it prints "<root@helos>: Sender address rejected: need fully-qualified address". Do you know how to configure Exim so that it sends e-mails from a valid address?

It looks like the entire system took a hit five days ago. Usually, that is not a problem. The Docker containers are set to restart automatically. While the ShinyProxy container did restart, the MariaDB container was damaged to an extent that Docker could not restart it.
But this should not have happen.
As I only check CollEc infrequently these days, I would like set up a notification system that sends an e-mail alert following critical errors. In particular, I would like to use the system outlined in this post: https://dummylabs.com/post/2018-08-15-monit/. It uses Monit to send e-mail alerts. Monit needs to be connected to an e-mail account / mail server. Is there a mail server on Helos that I can connect it to?
Sure it runs exim and it can send mail. I suspect that monit will be able to send mail from localhost. -- Cheers, Thomas Krichel http://openlib.org/home/krichel skype:thomaskrichel
