Hello Shal,
Many thanks for the elaborate reply. Why the error is happening is clear to me now.
We set up this mailing list for a collaboration between companies so ideally I and many colleagues would like to be able to send/receive emails properly. It is far from ideal to not be able to receive emails from colleagues from our own company (defeats the purpose of the mailing list).
What I don't get is how I can send/receive emails from my corporate email account to another mailing list (lists.onap.org) that is also set up in groups.io. The only difference is that the other group has its own domain (lists.onap.org). How isn't my email service rejecting these emails also?
Many thanks,?
Panos
