Hi I am trying to figure out an issue with my application running in docker and exploring this as a potential reason it is not working.
I have an application running in docker that is trying to authenticate with an SMTP relay using IP
On the server itself I am able to send an email to the SMTP relay so I know the IP configuration on that end is okay, however when I try to do this inside the container it does not authenticate - my suspicion is that it is because the SMTP relay is seeing it as a different IP due to it being in the container - is this something that might happen?
I cannot access SMTP relay logs to see what is happening so I can’t confirm this is the case, but if it could be is there a way I can ensure my docker container is using the correct IP for successful authentication?
many thanks
