hen sending to email recipienrts with gmail account

This is something you need to ask your email provider to fix. Just send them the message you quoted above and they will know what to do.

As i note in my post.
Sending via gmail using ms outlook works.
It is just emclient that it is not working with.

So it is an emclient issue.
