Email issues with docker image
Hello :-)

Actually i am looking for a nice monitoring solution which doesn't need stuff like nagios/icinga.

pandorafms looks interesting, so i went the easiest way and got the docker-compose file.

Image went up in no time, but currently i am stuck at the most crucial point: email notifications.

When entering the credentials, the test answer says:

Email could not been sent

I have double-checked them, also tried to use gmail or other stuff.
Always not possible.
Checking from the command line of the docker host: success

So, the first part would be checking the logs, but where to find these?
Is the docker image capable of outside-communication? Name resolution?

Edit: found audit log.

"Unable to connect with TLS encryption"
Well, our servers are capable of TLS, also Gmail and all the other ones i have tested.

Edit2: now it gets ridiculous
Then i thought, maybe there is some TLS issue, just set it to "none".
Expected response code 250 but got code "530", with message "530 5.7.0 Must issue a STARTTLS command first "

Edit3: logs mailserver

Try to follow the steps detailed for docker in the following link:

The docker has some problems regarding the mail, but they should be solved with the above mentioned.

If you have more problems, let us know and we will see how we can solve the problem.
