E-Mail when Duplicati run in Docker


I moved my Duplicati to a Docker Container.
I recognised that ther my system is not able anymore to send mails

Is there something special to do that Duplicati can send mails when it runs as a Docker Container ?

First guess - maybe DNS resolution isn’t working inside your container? Can you test that?

Do you know how I can check this

The easiest way may be to put the IP address in of your SMTP server instead of its host name.

I was going to suggest starting a shell prompt inside your container but standard DNS testing tools like nslookup are not included in the Duplicati docker image.

@drwtsn32 I never did this. When I am running duplicati on my QNAP as the native APP
I just write the lines


You don’t have --send-mail-url configured?
