I'm using https://hub.docker.com/r/osticket/osticket with an nginx server container at the front and no matter what I've tried - I can't manage to get it to send EMail. Although I can't view the logs from the dashboard due to the other ticket that I opened the ost_syslog table simply contains the error "Unable to email via php mail function:my_email_here mail() returned failure". Is there any way to see a more detailed log of the error?
Here's the configuration I'm using.
( the SMTP settings are correct as other containers are using the same env vars and do send EMail successfully)
System info (from the docker container)
