I've seen this topic before, but would like an update/suggested resolution. I regularly forward emails to my wife's account. Unfortunately, I am now getting this error back from her email server.

Surely it's a common requirement for a husband to forward emails to his wife. But apparently btinternet.com doesn't think so and I suspect it has blacklisted to some degree the zoho ip. So I'm now in the situation where I can't forward emails to my wife anymore.

Is there anything we can do?

Thanks
