Sender address rejected: not owned by user

Hi, is that e-mail address registered in your server?

Thank you

How would I check/add that? I do not remember having to register the current email that works.

Hi, what I meant to say is this. Did you add this new e-mail address in your server?

Thank you

This email exists in the server, yes.

I think your best option is to speak to your host about this issue. This issue is beyond this forum support. Our plugin has no control over servers settings.

Let me know what they say.

Thank you
