Unattended-upgrades with E-Mail Notification (smtp relay) on Oracle Cloud

Hello all,

this is not a typical hestiacp question but I hope you can help me.

I’m running hesticp on an Oracle Ubuntu Instance. I learned that Oracle blocks the sending of emails over php. Therefore I have configured an smtp relay (SendInBlue) in hestiacp.

My next step is to set up “unattended-upgrades” with email notification.

Do you have an idea how can I setup “unattended-upgrades” in combination with smtp relay configured in hestiacp?

I tried to setup mailx with smtp configuration (file .mailrc) but this don’t work.

Thanks for help
Tom
