Hi everyone,
In our airline we use Google Cloud Platform // cloud computing and for security reasons mailings can only be made through external clients in our case we are using mailgun and so we can send emails normally from our webmail and the mailgun statistics show exactly that.
The problem arises with phpVMS, I'm not sure, it is most likely the fault of how we are configuring it, but we do what we think is logical in the config.
If you can help us with instructions on how to configure it in more detail, because the phpVMS documentation is very general on this topic, we would greatly appreciate it.
