I recently left an employer who is forwarding emails to me for the next 90 days. However, many of the emails are not coming through. Below is typical email I get that says from "Postmaster". I'm not sure how to get around this. I've contact my former company and they can't answer it. I know I'm missing a lot of mail but not sure where it's going. Any suggestions that aren't too complicated for a non-techie to resolve this?
